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.
