Flange-Mount Check Valves for Oil and Fuel
Shown with Flanges (Not Included)
- For Use With: Butane, Diesel Fuel, Fuel Oil, Gasoline, Kerosene, Natural Gas, Oil, Propane
- Disc Material: 316 Stainless Steel
- Seal Material: 316 Stainless Steel
Install these valves between ANSI flanges. ANSI flanges are sold separately. All valves open to allow flow in one direction and close when flow stops or reverses. Body is 316 stainless steel for excellent corrosion resistance.
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.
