Threaded On/Off Valves
Use these valves in general purpose applications, such as those with water, oil, air, and inert gas.
Brass valves have good corrosion resistance to air, water, and oil. Plated brass valves are more corrosion resistant than plain brass and bronze valves. Bronze valves are stronger and more durable than brass valves for a longer service life. 316 stainless steel valves have the best corrosion resistance.
Full-port valves do not restrict flow. FM-approved valves are used in fire suppression systems. They help isolate parts of water supply systems in buildings and plants.
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.

Easy-Maintenance Threaded On/Off Valves
With a three-piece bolted body that disassembles for access to internal components, you can clean and repair these valves without unthreading them from your line.
Bronze valves resist corrosion from salt water and cleaning solutions used in machinery.
Steel valves are stronger and more durable than bronze valves for a longer service life.
316 stainless steel valves are more corrosion resistant than bronze or steel valves.
Lever handles are easy to turn and show the valve’s position. Lockable handles can be fixed in place using a padlock (not included).
Valves with actuator mounts can be equipped with air-powered or electric actuators using the mounting holes. This allows you to switch them from manual to automatic operation.
PTFE seals are the best choice for valves that are opened and closed often. The PTFE material forms a seal while remaining slippery, so it resists wearing down and failing with repeated use. Glass-filled PTFE seals resist expansion from water and heat. They’re ideal for systems that connect to heaters or hold fluids for extended periods.
Full-port valves do not restrict flow.
Maintenance kits include everything needed to replace the packing, seals, and seats on your valve.

Easy-to-Install Plastic Threaded On/Off Valves
A threaded union on these valves makes them easy to install and remove without disrupting your line. They’re a good choice for lines that require frequent maintenance or cleaning. They thread together or apart with only a turn to the union fitting, unlike other threaded on/off valves that require repositioning your pipe or valve. The union fitting slides over your pipe, and the threaded fitting sits inside. With a full port, these valves won’t restrict flow.
Made of plastic, they last longer than metal valves since the inside won’t corrode or pit. They’re also lighter in weight. PVC valves are commonly used in water lines. CPVC valves handle higher temperatures than PVC or polypropylene valves. They’re the best choice if your system connects to a heater.
Valves with a T-handle have a larger gripping surface than valves with a short lever handle, so they’re easier to turn when your hands are slippery.

Before you install the valve, slide the union fitting over your pipe, then insert the pipe into the socket fittings and bond with primer and cement. The union fittings allow the valve to be quickly removed where other socket-connect valves would require you to cut your pipe. A fluoroelastomer seal and plastic body withstand aggressive and corrosive solutions in chemical-processing applications. All valves have a T-handle that resists accidental movement when snagged or bumped. They are full port, so they do not restrict flow.
PVC valves are often used in mild chemical processing systems. CPVC valves resist heat better than PVC valves, so they’re a good choice for systems that connect to a heater. Lockable T-handles can be fixed in place using a padlock (not included).
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 wheel handle open and close with multiple turns, providing more controlled, shock-resistant flow than valves with a pull handle.
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. Valves with a nonrising stem keep the stem in the same position whether they’re open or closed. They’re often used underground and in low-clearance locations.
Valves with threaded union stem allow you to maintain and repair these valves while they’re still inline—you can disassemble the stem so there's no need to unthread the pipe connections. Bronze valves resist corrosion better than brass valves. They’re also stronger.
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.

Maintain and repair these valves while they’re still inline—you can disassemble the stem so there's no need to unthread the pipe connections. Also known as gate valves, they open and close gradually to prevent sudden starts and stops. Control the flow by turning the wheel handle multiple times. This gives you more control than a pull handle. Made of bronze, these valves have good corrosion resistance.
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.

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.
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. 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.
