HYDRAULIC DIFFERENTIAL UNLOADING VALVE The type DA 6 V pressure valve is a pilot-operated pressure cut-off valve with continuously adjustable switching pressure differential. It basically consists of pilot control stage and main stage of the screw-in cartridge valve (1), check valve (2) and housing (3). Via connection B, the pump volume flow in P is led into the system accumulator. If the pressure at the consumer in connection B exceeds the set upper switching pressure, the pilot control valve opens and control liquid can flow off via connection A (Y). The check valve (2) closes the connection of connection B to connection P and the pump volume flow is switched to zero-pressure circulation (from P to T). 1 To the consumer 2 High-pressure pump 3 Low-pressure pump Hydo system with pressure accumulator Hydo system with high and low pressure pump Dimensions: Model "2B" (dimensions in inches) Pressure* Description Order No. Price 360 . . . 725 psi DA6VP2B5X/50FSM R901224244 $473.00 Unloading Valve 725 . . . 1440 psi DA6VP2B5X/100FSM R901224235 $487.00 1440 . . . 2900 psi DA6VP2B5X/200FSM R901224238 $512.00 2175. . . 5075 psi DA6VP2B5X/350FSM R901224242 $593.00 *Differential is adjustable from 10% to 50% of the nominal value.
