ressure relief valve, pilot operated, sandwich plate type UZR0 NS0 up to,5 Ma up to 00 dm /min WK 497 00.0 LICION ressure relief valve, pilot operated, sandwich plate design type UZR0 0 is used to limit pressure in hydraulic systems. DESCRIION OF OERION ressure relief valve sandwich plate type UZR0 consists of a main body () and screwed-in relief cartridge valve pilot operated () type UZS6 according to catalogue sheet WK 49 860. roper drilling of the body allows connections as per hydraulic diagram for the version. When the pressure in the system exceeds the setting of the valve (), it opens, causing relief flow to port (for the version to port or ).
