Valcor Relief Valves provide over-pressurization protection with direct acting and/or pilot operated mechanical components. Our relief valves are available in dual ported (inlet and outlet ports) or ambient vented styles and are suitable for many different aerospace plumbing applications.


Valcor relief valves have applications in propulsion pressurant control for reaction control systems (RCS) and Attitude Control Systems (ACS), cabin over-pressurization control, and propellant tank pressure control.
