Pressure actuated valve saves cabling

HAWE Hydraulik SE, Munich, has developed a pressure actuated valve for AC and DC units that can be used with operating pressures up to a maximum of 800 bar. It is suitable for applications requiring a volume flow of up to 20 lpm: for example, in die-cutting technology and for high-pressure tools, torque wrenches, and forming tools.


The pressure actuated valve is designed as an intermediate plate with a 2/2-way seated valve and is mounted between the pump and connection block or connection to the consumers. The valve's switching response is set using orifice, as a function of the pump's volume flow. This enables the pressure actuated valve to be combined with different kinds of pumps, for example, with a compact power pack from HAWE Hydraulik. Single-acting consumers are retracted and extended solely by switching the unit on and off, without electric valve control.



Using a pressure actuated valve makes it possible to eliminate the release valve that is typically required. Because this is generally a solenoid valve, the use of a pressure actuated valve reduces the total cost of installation and cabling. It also facilitates the control of the hydraulic system.

Compared with spool valves, this pressure actuated valve also reduces the energy requirement: because it is a directional seated valve, it is leak-free in the closed position, so there is no additional leakage. It also offers highly reliable switching over a long lifespan.
