Relief Cartridges

Sun Hydraulics offers pressure-limiting and pressure-regulating relief cartridges with a variety of mounting options with 2, 3, or 4 ports.

A selection of relief valves and assemblies

Functionally interchangeable (except pilot-only versions) with valves with the same number of ports (same flow path, same cavity for a given frame size)
Flow rates up to 200 gpm (800 L/min.)
Versions are available with an integral pilot control cavity that accepts Sun's T-8A pilot pressure controls — electro-proportional or pneumatic
Fully adjustable up to and including 5000 psi (350 bar) or 6000 psi (420 bar) intermittent, except air-piloted versions
