Bypass Pressure Compensator series DWVPA-2B, DWVPY-2B

Pressure [bar]


Flow rate [l/min]


These two-stage bypass pressure compensator (hydrostat) cartridges, series DWVPA-2B-… / DWVPY-2B-… / DWVPZ-2B-… are size 16, high performance screw-in car tridges with an M42x2 mounting thread. The cartridges have a seated pilot stage, and the main stage is designed on the sliding-spool principle. Three models can be sup plied, with compensator spring settings of 8 bar (version “A”), 12 bar (version “Y”), or 5 bar (version “Z“). Due to the fixed compensator-spring setting, the control pressure diffe rence between inlet and outlet pressure in hydraulic circuits- for example, across a throttle (an orifice) – is maintained at a constant level. This means that the flow rate is indepen dent of the load pressure at the actuator. The compensator cartridges are also provided with an integral pressure-relief function, available in 6 different pressure ranges. The 1→2 pressure-relief function requires a damping orifice before the port 3. A suitable orifice is already incorporated in the screw-in cartridge and is therefore not needed in the mani fold block. To safeguard pressure settings, the adjusting screw can be sealed with a tamper-proof cap. Pilot oil is drai ned internally to port 2.

  • Choice of 5, 8 or 12 bar compensator spring
