Relief

Cartridge style relief valves are designed to limit pressure in hydraulic circuits up to 5000 psi.  Relief pressure settings can be either fixed or adjustable and either direct acting or pilot operated.  Optional designs include anti-cavitation and tamper resistance, as well as a thermal relief valve for temperature induced pressure spikes.
