High-Pressure Valves

Schrader Pacific high-pressure valves are constructed of stainless-steel bodies and are intended for use in high-pressure air-charged units, such as shock absorber struts, hydraulic pressure accumulators, surge cylinders, and pneumatic systems. These valves have a special feature that warns of unreleased air pressure when the valve is being separated from the outlet. Valves have ½ʺ-20 UNJF-3A threads for connection to container. Contact Schrader Pacific for further information on military and commercial adaptations.

Schrader Pacific high-pressure connectors are available in multiple configurations and handle air pressures up to 15,000 psi. They can be fitted to gaging and inflating devices by a variety of methods. Various angles permit easy attachment to hard-to-reach valves.

Note: Due to the variety of operating conditions and applications, the customer is responsible for performing testing to ensure performance and providing safety and warning requirements for the intended application.
