Pressure relief valves series DVPA-1-10… are 2-stage cartridges with a positive seat pilot stage and spool-type main stage. When the pilot stage is active (main stage relieving), pilot oil is internally drained to port B. Any pressure in port B is additive to the spring pressure setting, therefore port B should preferably be connected to tank. Thoroughly oil or grease external seals before inserting the cartridge in a DC cavity. The cartridge can be tightened with a 27 A/F OE spanner (note the recommended tightening torque). Form tools are available for sale or hire, should customers wish to machine cavities in their own control blocks. The BUCHER line- and manifold-mounting body type DC-12 can be used where the application requires a line mounting valve. The cartridge can also be supplied with an integral reverse flow check valve: Type DVPA-RV-1-10 …
