High Pressure Valves

Schrader High-Pressure Valves are constructed of stainless-steel bodies for use in high-pressure air-charged units such as shock absorber struts, hydraulic pressure accumulators, surge cylinders, and pneumatic and hydraulic systems. Most of these valves have a special feature that warns of unreleased air pressure when the valve is being separated from the outlet. These valves have ½”-20 U.N.F.-3A threads for connection to the container.

Schrader High-Pressure Connectors are available in multiple configurations, and handle air pressures up to 15,000 psi. Several air line connection sizes are available. Many of these valves also include a depressor pin that can open the valve before filling, and allow it to close before disengaging the connector.

Note: Due to the variety of operating conditions or applications, the customer is responsible to perform their own testing to insure performance, safety and warning requirements for the intended application.
