About Gradual On/Off Valves
More
Threaded Gradual On/Off Valves
Also known as gate valves, these gradually open and close to prevent system damage from suddenly starting and stopping flow.
Pull handles open and close faster than wheel handles.
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.
- Valve Type: Gate
- For Use With: Oil, Air, Argon, Helium, Krypton, Neon, Xenon

Plastic Threaded Gradual On/Off Valves
- Valve Type: Gate
- For Use With: Water
- Seat Material: See Table
Plastic provides an economical and lightweight alternative to metal. These valves gradually open and close to prevent system damage from suddenly starting and stopping flow. Pull the handle to open the valve. All valves have a rising stem that lifts as the valve opens and lowers as the valve closes to provide a visual indication of whether flow is on or off.
304 stainless steel gates are more durable than glass-filled polypropylene gates.

Flanged Gradual On/Off Valves
Rising Stem, and

Bolt these valves to flanges. They gradually open and close to prevent system damage from suddenly starting and stopping flow.
Pull handles open and close faster than wheel handles.
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.

- Valve Type: Gate
- For Use With: Water
For a lightweight and economical alternative to metal valves, these are made of plastic. Insert unthreaded pipe into the socket ends and bond with PVC primer and cement to create a permanent, leak-tight connection. Valves gradually open and close to prevent system damage from suddenly starting and stopping flow. Pull the handle to open the valve. All valves have a rising stem that lifts as the valve opens and lowers as the valve closes to provide a visual indication of whether flow is on or off.
