RV08-20 Direct acting cartridge pressure relief valve is designed as poppet type and direct-acting pressure control relief cartridge valve which is installed as threaded screw in largely saving the mounting space. The RV08-20 cartridge pressure relief valve should be equipped with valve block where the 1 to 2 port comes across in order the RV08-20 valve to block the flow from 1 to 2 until sufficient pressure at the 1 port have enough pressure to push the spring to opposed position from its seat.

RV08-20 cartridge pressure relief valve valve supplied by Finotek are all hardened of working surface, and with surface treatment of zinc plated to antirust exposed surface. And all of its cartridge valve anodized aluminum housing, valve cavity tooling and parts are available for future normal operation.
