About Gradual On/Off Valves
More
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 spring-close lever handle open when you pull on the handle and close when you release it. The handle is also called a deadman’s handle. Use these valves where the volume of flow needs to be closely monitored to avoid overflowing and spillage. 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.
Brass valves have good corrosion resistance. They also have a more polished look than bronze valves. However, they’ll corrode from salt water. 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.

Easy-Maintenance Threaded Gradual On/Off Valves
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 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.

Threaded Gradual On/Off Valves for Cryogenic Liquid

- Valve Type: Gate
- For Use With: Liquid Argon, Liquid Carbon Dioxide, Liquid Natural Gas, Liquid Methane, Liquid Nitrogen, Liquid Oxygen
- Packing Material: PTFE Plastic
- Specifications Met: ASME B31.3, CGA G-4.1, MSS-SP-80
Built to handle the extreme cold of liquid gases, these bronze valves are ideal for liquid carbon dioxide carbonation systems, liquid nitrogen coolant systems, and other cryogenic applications. They’ll also work with liquified natural gas and liquid oxygen. They’re cleaned and bagged to meet CGA G-4.1 for oxygen service. Also known as gate valves, they open and close gradually with multiple turns of the wheel handle to prevent sudden starts and stops.
The handle raises as these valves open and lowers 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. They have a threaded union stem housing, so you can separate the stem from the housing while the valve is inline. That means you can complete maintenance tasks, such as packing the stem, without taking apart your whole setup.

Easy-to-Install Threaded Gradual On/Off Valves


- Valve Type: Gate
- For Use With: See table
- Packing Material: PTFE Plastic
A threaded union on these valves makes them easy to install and remove without disrupting your line. 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. They’re often connected to tanks in control rooms and to radiators. Also known as gate valves, they open and close gradually with multiple turns of the wheel handle to prevent sudden starts and stops. With a nonrising stem, the handle stays in the same place whether these valves are open or closed.
Brass valves have good corrosion resistance. They also have a more polished look than bronze valves.
Bronze valves resist corrosion better than brass valves, including from salt water. They’re also stronger.

FM-Approved Threaded Gradual On/Off Valves

- Valve Type: Gate
- For Use With: Water
- Packing Material: Graphite
- Specifications Met: FM Approved, UL-Listed, C-UL Certified
FM-approved for fire suppression and protection, these valves can isolate sections of the water supply in your facility. Also known as gate valves, they open and close gradually with multiple turns of the wheel handle to prevent sudden starts and stops of flow. The stem raises the handle up as these valves open and lowers 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. Made of bronze, they have good 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.

Gradual On/Off Valves with Solder-Connect Fittings


- Valve Type: Gate
- For Use With: Water, Oil
- Specifications Met: MSS-SP-80
Solder these valves to copper tubing for a permanent, leak-tight connection. They gradually open and close with multiple turns of the wheel handle to prevent system damage from suddenly starting and stopping flow.
Nonrising stems stay in the same position whether the valve is open or closed. Valves with nonrising stems are often used underground and in other low-clearance locations.
Rising stems lift as the valve opens and lower 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 longer service life 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.

Gradual On/Off Valves with Press-Connect Fittings


- Valve Type: Gate
- For Use With: Water
- Specifications Met: MSS-SP-80
For a leak-tight connection, crimp the press-connect fittings on these valves to metal tubing with a crimping tool (not included)—no heat or soldering required. The fittings are comparable to Viega fittings. These valves open and close gradually as the wheel handle turns, preventing sudden starts and stops of flow. They’re also known as gate valves. Made of bronze, they have good corrosion resistance.
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 up 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.

Gradual On/Off Valves with Press-Connect Fittings for Drinking Water


- Valve Type: Gate
- For Use With: Drinking Water
- Specifications Met: NSF/ANSI 61
For a leak-tight connection in drinking water lines without heat or soldering, crimp the fittings on these valves to metal tubing with a press-connect crimping tool (sold separately). The fittings are comparable to Viega fittings. Also known as gate valves, they open and close gradually to prevent damage to your system from sudden changes in flow. Safe for use in drinking water systems, these valves meet NSF/ANSI 61. They have good corrosion resistance since they’re made of bronze.
Valves with nonrising stems fit well underground and in other low-clearance places since the handle doesn’t move up when the valve opens.
Valves with rising stems let you see at a glance whether flow is on or off. The handle rises as the valve opens and lowers as it closes. The stem stays separate from the material flowing through your line, reducing corrosion so they last longer than valves with nonrising stems. With a long lifespan, you can use them for critical lines and lines that need to be opened and closed frequently.
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.
