Stainless Steel Check Valve – 1/2" MNPT x MNPT, 1 psi Crack Pressure, 6000 psi (SHCV2-S-8-1P)
The SHCV2-S-8-1P is a compact, high-pressure check valve built from solid 316 stainless steel for use in aggressive fluid environments where backflow prevention is non-negotiable. Designed with dual 1/2" MNPT threaded ends, this spring-loaded poppet valve opens at a nominal 1 psi cracking pressure, ensuring minimal resistance in forward flow while instantly closing to seal out reverse pressure spikes.
Its robust design supports working pressures up to 6000 psi, making it suitable for compressed gas systems, hydraulic circuits, Clean-in-Place (CIP) instrumentation, and general process safety lines. The one-piece body design reduces leak paths, and its flow direction is clearly marked for easy field installation. This valve is also commonly used in OEM skids and hygienic fluid processors where compact form factor and high reliability are essential.
Whether you’re designing a sanitary stainless steel fittings loop or protecting downstream instruments in a pressure control setup, the SHCV2-S-8-1P provides corrosion-resistant alloy durability and flow assurance with zero compromise.
