Flow rate [L/min]

Series DVPA-2-10… cartridges are 2-stage pressure relief valves 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. By connecting a separate pressure control valve (eg. type DPA-3) or directional control valve (eg. type WR22…) to the remote control port Z, the cartridge can be controlled or vented from a distant location. Thoroughly oil or grease external seals before inserting the cartridge in a DD 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 BUCHERline- and manifoldmounting body type DD-12 can be used where the application requires a line mounting valve.
