About Gradual On/Off Valves

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.

Threaded Gradual On/Off Valves for Chemicals
- Valve Type: Gate
- For Use With: See Table
- Seal Material: Fluoroelastomer Rubber
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.
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.
