Hoke Poppet Check Valves 6000 psi 316 Viton 1/4"NPT-F 1/4"NPT-F
Ball Check Valves
The Hoke 6200 Series poppet check valves are compact instrumentation valves designed to prevent reverse flow in high-pressure gas and liquid systems. These valves utilize a spring-loaded poppet design that delivers fast response, reliable sealing, and stable cracking pressure characteristics under varying operating conditions. The precision-machined internal components minimize leakage and ensure dependable long-term performance in demanding applications. Constructed primarily from 316 stainless steel, the series offers excellent corrosion resistance and compatibility with a wide range of industrial media. Multiple cracking pressure options and end connection styles are available to support flexible system integration. Operating pressures are rated up to 6000 psig (414 bar) depending on valve configuration. Typical applications include analyzer systems, sampling panels, hydraulic circuits, pump protection, and general instrumentation requiring reliable backflow prevention.
