Bypass Pressure Compensator series DWDPA-2B

These direct-acting bypass pressure-compensator (hydrostat) cartridges, series DWDPA-2B…-16…, are size 16, high performance screw-in cartridges with an M42x2 mounting thread. The main stage is designed on the sliding-spool principle, and it can be set between 5…13 bar using the adjustable compensator spring. Pressure-compensator cartridges maintain the control pressure difference between inlet and outlet pressure – for example, across a throttle (an orifice) – at a constant level. This means that the flow rate is independent of the load pressure at the actuator. The adjusting screw or the hand-knob enable the user to carry out system optimisation directly on the equipment, without any need to install or replace components that have different flow ranges (e.g. proportional valves). To safeguard valve settings, the adjusting screw can be sealed with a tamper-proof cap. By fitting external pilot controls (pressure-relief valves or 2/2 unloading valves) in the line to the port 3, additional functions such as pressure relief or vented bypass from 1→2 can be produced.
