Swagelok SS-CHS4-10 Poppet Check Valve, 1/4 in., 10 psi Cracking

Stop backflow cold with the SS-CHS4-10 poppet check valve. This CH Series valve uses a spring-loaded poppet that seats fast and holds, so your pumps, gauges, and analyzers stay protected from reverse flow. The 10 psi cracking pressure gives you a firm hold-off, ideal when you want the valve to stay shut until real forward pressure builds. You get 1/4 in. Swagelok tube fitting ends that connect straight to your tubing, a 316 stainless steel body that resists corrosion, and a fluorocarbon FKM seal with a PTFE backup ring for a tight shutoff. It handles a full 6000 psig at room temperature and moves flow up to 0.67 Cv. Put it to work on refinery, chemical, and high-purity systems where clean, one-way flow keeps your instruments safe.
