POWERTECH poppet or ball check valves are available in stainless steel and are rated up to 10,000 psi. Our check valves ensure one-way directional flow, preventing back-flow during normal system operation or maintenance. PVI check valves are used in systems where back-flow can be detrimental to system safety and performance, eliminating system contamination and reducing the risk of mixing. PVI Check Valves are designed with high integrity leak rates & resealing capabilities for unidirectional flow of fluids & gases in Chemical, Processing, Oil & Gas production & transmission, Pharmaceutical, Power & Utilities.
