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.
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.

The fluoroelastomer seal and plastic body can stand up to aggressive and corrosive solutions, so these valves are often used in chemical-processing applications. They gradually open and close with multiple turns of the wheel handle to prevent system damage from suddenly starting and stopping flow. All have a nonrising stem that stays in the same position whether the valve is open or closed.
