Inverse Proportional Pressure Relief Cartridge Valve series DBVSA-1CG

Pressure [bar]


Flow rate [l/min]


Inverse proportional pressure relief valves series DBVSA-1CG… are size 10, two stage screw-in cartridges with a M24x1.5 mounting thread. They consist of a spool-type main stage and a leak-free, poppet-type pilot stage with a falling pressure/current characteristic. Thanks to the damp ing of the solenoid armature, these pressure-relief car tridges exhibit excellent stability over the whole pressure and flow range. With these proportional pressure-relief car tridges, the relief pressure is dependent on the electrical control current and can be continuously varied. When the solenoid is de-energised (initial position), the relief pressure is the nominal pressure of the applicable spring range (failsafe function). Any pressure at port B is additive to the valve setting at port A, therefore port B should preferably be con nected directly to tank. In control mode, the relief pressure is inversely proportional to the change in the required value (amplifier output current). In order to obtain precise pres sure settings over the whole of the required pressure range (optimum resolution), the pressure relief cartridges are available in six spring ranges.
