Stainless Steel One-Piece Check Valve – 1/4" MNPT x MNPT, 1 psi Crack, 3000 psi (SOCV1-M-4N-1P)
The SOCV1-M-4N-1P is a stainless steel one-piece check valve designed for low cracking pressure and dependable reverse flow protection in tight pressure system configurations. With 1/4" Male National Pipe Taper (MNPT) threads on both ends and a spring-loaded poppet that opens at just 1 psi, this valve offers fast-acting relief and compact inline installation.
Its one-piece machined body eliminates potential leak points common in multi-part valve assemblies. Made from 316 stainless steel, the SOCV1-M-4N-1P withstands pressure up to 3000 psi and resists corrosion from aggressive gases and process media. It’s ideal for gas lines, hydraulic control, instrumentation loops, and Original Equipment Manufacturer (OEM) systems requiring slim, high-integrity components.
No field assembly is needed—simply thread it in, and it’s ready for immediate use.
