About Gradual On/Off Valves

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 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.

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.

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.
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.
