Flanged On/Off Valves

Bolt these valves to ANSI flanges. Their lockable lever handle can be fixed in place using a padlock (not included). All have four mounting holes to install an actuator, so you can convert them from manual to automatic valves.
Steel valves stand up to corrosion better than cast iron valves. 316 stainless steel valves are more corrosion resistant than cast iron and steel valves.
Full-port valves do not restrict flow. Standard-port valves slightly restrict flow.
Pressure class 150 valves are standard and work for most low-pressure applications.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Socket-Connect On/Off Valves for Drinking Water


- Valve Type: Ball
- For Use With: Drinking Water
- Seal Material: EPDM Rubber
- Specifications Met: NSF/ANSI 61
Insert unthreaded pipe into the socket ends and bond with primer and cement to create a permanent, leak-tight connection. These valves meet NSF/ANSI 61, which means they’re safe to use with drinking water systems. They are full port, so they do not restrict flow.
PVC valves are made of the standard material used in most drinking water systems. CPVC valves resist heat better than PVC valves, so they’re better for water systems connected to a heater.
T-handles resist accidental movement when snagged or bumped. Lever handles are easy to open and close—they give you the most leverage of any handle type.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Threaded Gradual On/Off Valves
Also known as gate valves, these valves gradually open and close to prevent system damage from suddenly starting and stopping flow.
Valves with a pull handle open and close faster than valves with a wheel handle. Also known as slide valves, they’re often used to control flow in air conditioning and ventilation systems.
Valves with a rising stem lift the handle as they open and lower it as they close. At a glance, you can see if flow is on or off. The stem is isolated from what’s flowing through your line, giving these valves a longer lifespan than valves with a nonrising stem.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Easier to install and remove than threaded or weld-on valves, these valves bolt to flanges. They’re often used in lines requiring frequent cleaning and maintenance, such as those for slurries. They open and close gradually, preventing system damage from sudden starts and stops in flow. Also known as gate valves.
Valves with a wheel handle open and close with multiple turns, providing more controlled, shock-resistant flow than valves with a pull handle. Valves with a pull handle, also known as slide valves, open and close faster than valves with a wheel handle. They’re often used as blast gates for precise flow control in low-pressure air conditioning and ventilation systems.
Valves with a nonrising stem keep the handle in the same position whether they’re open or closed. They're often used in low-clearance locations. Valves with a rising stem lift the handle as they open and lower it as they close. At a glance, you can see if flow is on or off. The stem is isolated from what’s flowing through your line, giving these valves a longer lifespan than valves with a nonrising stem. This makes them good for critical lines and lines that need to be opened and closed frequently.
Cast iron valves are stronger than steel valves but more brittle than steel, ductile iron, and stainless steel valves. Steel valves resist impact better than cast iron valves. Ductile iron valves are stronger and more durable than cast iron valves, handling greater pressure changes without cracking. 316 stainless steel valves have the best corrosion resistance.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

FM-Approved Flanged Gradual On/Off Valves
FM-approved, these valves are often used to isolate sections of your facility’s water supply for fire suppression and protection. They bolt to flanges for easier installation and removal than threaded or weld-on valves. This makes them a great choice if you have to clean and maintain your line frequently. Also known as gate valves, they open and close gradually to prevent sudden starts and stops of flow that could damage your system. Epoxy coated, these valves resist corrosion. They’re bright red, so they’re easy to identify as fire valves.
Their rubber-coated gate, also known as a resilient wedge, compresses against the valve for a long-lasting, leakproof seal. It seals tightly even if you install these valves vertically, or if there’s low back pressure. For easy disassembly during maintenance, they have a flanged stem housing that bolts in place. However, the housing makes these valves heavier and larger than valves with a threaded or welded stem housing.
Valves with a wheel handle open and close with multiple turns for controlled, shock-resistant flow. Wrench-operated valves are the best choice for hard-to-reach locations, such as underground or inside a manhole. Operate them from a distance with a valve wrench. You can also open and close them with a fire indicator post.
Valves with a nonrising stem keep the handle in the same position whether they’re open or closed. They're often used underground and in low-clearance locations. Valves with a rising stem lift the handle as they open and lower it as they close. At a glance, you can see if flow is on or off. The stem is isolated from what’s flowing through your line, giving these valves a longer lifespan than valves with a nonrising stem. This makes them good for critical lines and lines that need to be opened and closed frequently.
Ductile iron valves are stronger and more durable than cast iron valves. They’ll handle greater pressure changes without cracking.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

- Valve Type: Gate
- For Use With: Air, Argon, Deionized Water, Ethanol, Ethylene Glycol, Helium, Isopropyl Alcohol, Krypton, Methanol, Neon, Nitrogen, Salt Water, Soap Solutions, Water, Xenon
These valves have a sharp gate that slices through thick slurries, wastewater, dry bulk solids, and other materials that would clog other gradual on/off valves. They bolt to flanges and gradually open and close to prevent system damage from suddenly starting and stopping flow. The wheel handle opens and closes the valve with multiple turns, providing controlled, shock-resistant flow. The rising stem lifts as the valve opens and lowers as the valve closes to provide a visual indication of whether flow is on or off. The stem is isolated from the process media for a long service life.

Tight-Seal Flanged Gradual On/Off Valves
A rubber-coated gate, also known as a resilient wedge, compresses against the valve seat to give these valves a tight, leakproof seal. They shut tight even when they’re installed vertically, have low back pressure, or the liquid contains solids and debris. Often called gate valves, they open and close gradually to prevent sudden starts and stops that can damage your system. Since they bolt onto flanges, they’re easier to install and remove than threaded and weld-on valves. This makes them a good choice for lines that need frequent cleaning and maintenance. You can use them in lines for water supply, reclamation, and wastewater treatment—they meet AWWA (American Water Works Association) specifications. To protect against corrosion, the body is coated with epoxy.
The stem is nonrising, so it stays in the same position whether the valve is open or closed. They’re often used in low-clearance spots. Their flanged stem housing bolts in place to make them easy to take apart for repairs. However, the flanged stem housing makes these valves heavier and larger than valves with threaded or welded stem housings.
Wrench-operated valves work well in hard-to-reach places, such as underground or the bottom of manholes, since you can turn the flow on or off from a distance. Open and close them with T-handle valve wrenches.
Ductile iron valves are stronger and more durable than cast iron valves, handling greater pressure changes without cracking.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Flexible joints keep these valves tightly sealed during pressure changes or vibrations from heavy machinery. Also known as gate valves, they gradually open and close to prevent system damage from sudden flow changes. They have a rubber-coated gate that compresses against the valve for a long-lasting, leakproof seal. They’ll seal tightly even when installed vertically, when there’s low back pressure, or when the liquid contains solids and debris. Made of ductile iron, these valves are stronger than cast iron valves and resist cracking from pressure changes. The body is coated with epoxy to protect against corrosion. They meet at least one American Water Works Association (AWWA) standard for reliable and safe performance in water supply systems.
These valves fit well in tight spaces since the stem doesn’t rise when they open. Their flanged stem housing bolts in place for easy disassembly for maintenance and repairs. Use a valve wrench to open and close these valves. Because they require a wrench, they can’t be opened accidentally when bumped or snagged.
FM-approved valves are used in fire suppression and protection systems. They help isolate parts of water supply systems in buildings and plants.
Valves that meet NSF/ANSI 61 are safe to use with drinking water systems.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Gradual On/Off Valves with Push-to-Connect Fittings

- Valve Type: Gate
- For Use With: Water
- Seal Material: Buna-N Rubber
- Specifications Met: AWWA C515
For strong, permanent connections that are quick to install, push PVC pipe into these valves and a rubber ring grips it. Also known as gate valves, they open and close gradually to prevent damage to your system from sudden changes in flow. They meet AWWA (American Water Works Association) C515 for use in large-scale industrial cleaning and cooling water lines. Made of ductile iron, these valves are stronger than cast iron valves, so they resist cracking from pressure changes. The body is coated with epoxy to protect against corrosion. These valves have a rubber-coated gate, also known as a resilient wedge, that compresses against the valve for a long-lasting, leakproof seal. They'll seal tightly even when installed vertically, there's low back pressure, or the liquid contains solids and debris.
These valves fit well in tight spaces since the stem doesn’t rise when they open and they don’t have a handwheel. They’re wrench operated, which prevents them from opening accidentally when bumped or snagged. Use a valve wrench to open and close the valve with minimal effort. Their flanged stem housing, also known as a bolted bonnet, bolts in place so you can take them apart for repairs. However, the flanged stem housing makes these valves heavier and larger than valves with threaded or welded stem housings.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Flanged Air-Driven On/Off Valves

- Valve Type: Butterfly
- For Use With: Water, Air, Argon, Helium, Neon, Steam, Xenon, Krypton, Drinking Water
- Seal Material : EPDM Rubber
- Specifications Met: API 609, NSF/ANSI 61
To automatically start and stop flow faster than motor-driven valves, these operate on compressed air. You must control the air to the actuator using either the included electric pilot valve or a manual on/off valve (not included). Valves don’t require a minimum pressure drop between the inlet and outlet for operation.
The actuator is directly mounted to the valve body to minimize movement and reduce wear. A visual flow indicator on the top of the actuator shows whether the valve is open or closed. The manual override allows you to operate the valve during power outages. Valves meet NSF/ANSI 61 for use with drinking water.
All valves are lug style; their hole pattern matches ANSI flanges of the same pipe size. They can be sandwiched between two flanges, or bolt them directly to a single flange for servicing one end of the pipeline without depressurizing the other side.
Single-acting actuators only require air pressure to open the valve; they automatically spring closed when the air turns off. These valves are normally closed unless actuated. Double-acting actuators require air pressure to open and close the valve. Once actuated, these valves remain actuated until air pressure is applied, so they do not have a valve starting position.

Plastic Flanged Flow-Adjustment Valves for Chemicals

- Valve Type: Butterfly
- For Use With: Water, Carbon Dioxide, Citric Acid, Hydrochloric Acid, Isopropyl Alcohol, Kerosene, Phosphoric Acid, Salt Water
- Seat Material: Fluoroelastomer Rubber
- Specifications Met: FM Approved
In addition to fluoroelastomer seats that resist a wide range of chemicals, these valves have no metal parts to corrode, so they’re often used for chemical-processing applications in corrosive conditions. All bolt to flanges for adjusting and regulating flow in flanged pipelines. Fix the lockable lever handle in place using a padlock (not included) with a shackle diameter up to 7/16”. Valves are wafer style, so they must be sandwiched between two flanges; all have unthreaded holes to help align the valve between the flanges.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Flange-Mount Pressure-Relief Discs
Install these discs within the bolt circle of ANSI Class 150 flanges. They break open at the burst pressure to allow unrestricted flow. All are for one-time use. Discs are made of resin-impregnated graphite for resistance to temperature and pressure fluctuations as well as corrosive liquids and gases. They include two gaskets for installation between flanges.
Vacuum-rated discs have supports to resist rupture caused by vacuum.
Operating ratio is the ratio between the normal operating pressure and the burst pressure. Exceeding the operating ratio decreases the service life of the disc. For example, a disc with a burst pressure of 100 psi and an operating ratio of 80% should not be used in a system with an operating pressure greater than 80 psi.
