High Pressure Check Valves
High Pressure Check Valves for Pressures up to 60,000 PSI
Ped-lock High-Pressure Check Valves are spring-loaded, non-return valves designed to provide reliable one-way flow control in liquid and gas systems operating at pressures up to 60,000 PSI (4,137 Bar). These valves utilize a guided poppet design with replaceable springs to ensure positive sealing and dependable backflow prevention in critical high-pressure applications.
Designed for use with high-pressure cone and thread tubing systems, Ped-lock check valves are manufactured from cold-worked Type 316 stainless steel and are available with multiple cracking pressure options to suit a wide range of service requirements.

Operation
The valve remains closed until inlet pressure exceeds the cracking pressure and system back pressure. When the differential pressure across the poppet exceeds the spring force, the valve opens to permit forward flow. Reverse flow forces the poppet against the seat, providing positive shut-off and preventing backflow.
