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.

- 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.

Socket-Connect Gradual On/Off Valves for Chemicals
- Valve Type: Gate
- For Use With: Water, Carbon Dioxide, Citric Acid, Hydrochloric Acid, Isopropyl Alcohol, Kerosene, Natural Gas, Phosphoric Acid, Propane, Salt Water
- Seal Material: Fluoroelastomer Rubber
For a permanent, leak-tight seal, insert unthreaded pipe into the socket ends on these valves and bond with primer and cement. To withstand aggressive and corrosive solutions in chemical-processing applications, they have a fluoroelastomer seal and a plastic body. All gradually open and close with multiple turns of the wheel handle to prevent system damage from suddenly starting and stopping flow. Valves have a nonrising stem that stays in the same position whether the valve is open or closed.
Use repair kits to replace worn-out seals.
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.

Plastic Socket-Connect Gradual On/Off Valves for Drinking Water
- Valve Type: Gate
- For Use With: Drinking Water
- Seal Material: See table
- Specifications Met: NSF/ANSI 61
Bond these valves to plastic pipe with PVC primer and cement (not included) to create a permanent, leak-tight connection in drinking water lines. Also known as gate valves, they open and close gradually to prevent damage to your system from sudden changes in flow. Turn the handle multiple times to start or stop flow. Safe for use in drinking water systems, these valves meet NSF/ANSI 61. They’re plastic, so they’re lighter in weight than metal valves.
All have a nonrising stem, which means that the handle won’t move up as the valve opens. This makes them good for underground and other low-clearance applications.
CPVC valves handle temperatures up to 200° F, so you can use them in hot drinking water applications.
Use repair kits to replace worn seals.
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.

Plastic Flanged Gradual On/Off Valves for Drinking Water
- Valve Type: Gate
- For Use With: Drinking Water
- Seal Material: Buna-N Rubber
- Specifications Met: NSF/ANSI 61
Easier to install and remove for maintenance than threaded and weld-on valves, these valves bolt and unbolt to flanges. They meet NSF/ANSI 61 for safe use in drinking water systems. Also known as gate valves, they open and close gradually with multiple turns of the wheel handle to prevent damage from sudden starts and stops in flow. Whether these valves are open or closed, the handle stays at the same height because of the nonrising stem. This helps them fit in low-clearance areas, such as underground lines. All are plastic, making them a lightweight alternative to metal valves. When the seals wear out, replace them using repair kits (sold separately).
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.
