Threaded Check Valves for Oil and Fuel
These valves open to allow flow in one direction and close when flow stops or reverses. They function both horizontally and vertically. When vertical, the flow arrow must point up.
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.

Socket-Connect Check Valves for Oil and Fuel

Insert unthreaded pipe into the socket ends and weld to create a permanent, leak-tight connection. These heavy duty valves can withstand pressures up to 1,975 psi and temperatures up to 800° F. They open to allow flow in one direction and close when flow stops or reverses. A removable cap provides easy access to internal components for maintenance.
Spring-loaded ball check valves resist sticking and clogging better than spring-loaded piston check valves.
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.

Butt-Weld Check Valves

- For Use With: Air, Argon, Helium, Krypton, Neon, Water, Xenon
- Piston Material: 316 Stainless Steel
- Spring Material: 316 Stainless Steel
- Seal Material: Viton® Fluoroelastomer
Weld these valves to unthreaded pipe for a smooth, flush connection that provides maximum flow. All open to allow flow in one direction and close when flow stops or reverses. They have a 316 stainless steel body 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.
