Hydac Pressure Compensator DWY08130

Hydac Pressure Compensator DWY08130

The pressure compensator DWY08130 is a direct-operated, spring-loaded flow control valve, which is normally open. By maintaining a constant differential between inlet and outlet pressure of an orifice a constant flow rate is maintained.  As soon as the pressure differential exceeds the value pre-set by the spring force the control piston reduces an orifice cross-section. The pressure compensator can, for example, be used when lowering variableloads at the same velocity. Together with a proportional flow control valve it can be used as a 2-way proportional flow regulator.
In load sensing circuits in which actuators are operated in parallel, each one can be individually speed-controlled.

GENERAL

• Used to control the flow rate of actuators independently of the load.
• Available in models for two different control pressure differentials and for flow rates of up to max. 30 l/min.
• Excellent stability over the whole pressure and flow range.
• Excellent dynamics.
• All surfaces zinc-plated and corrosion-proof.
• Minimal wear and long service life due to hardened and ground valve components.
• Rigid design using one-piece body minimises the effect of eccentricities in cavity and maximises reliability.
• Reliable operation due to integral stroke limitation.
• Internal relief of the load sensing line.
