Hoke Ball Check Valves 6000 psi 316 Viton 1/4"NPT-F 1/4"NPT-F
Ball Check Valves
The Hoke 6100 Series Ball check valves are compact high-pressure valves designed to provide reliable one-directional flow control and prevent reverse flow in instrumentation and process systems. These valves feature a precision-guided poppet design that ensures fast response, dependable sealing, and low leakage performance across a wide range of operating conditions. Constructed from durable materials such as 316 stainless steel, the series offers excellent corrosion resistance and long service life in demanding gas and liquid applications. Various cracking pressure options are available to suit different system requirements and installation orientations. Operating pressures are rated up to 6000 psig (414 bar) depending on configuration. Typical applications include sampling systems, hydraulic circuits, analyzer systems, pump protection, and general instrumentation requiring reliable backflow prevention.
