Proportional Pressure Control Valve EPDRD3-05
The 3-way proportional pressure control valve EPDRD3 size 05, is a direct operated valve in spool design. The consumer pressure is proportionally adjustable to the solenoid current. Thanks to its very small oil leakage values and low minimum pressure, it is suitable for low-loss hydraulic systems, such as memory-, clamping- or braking systems, pilot functions or static loading systems.
The direct operated 3-way proportional pressure control valve EPDRD3-05 reduces an inlet pressure to a lower consumer pressure. Oil keeps flowing from port 2 (P) to 1 (A) until the setpoint pressure is reached, then the valve closes. The valve opens up again from 2 (P) to 1 (A) when the consumer pressure drops. If the setpoint pressure is exceeded on the consumer side, the pressure relief function of the valve is activated (three-way function). Oil will then flow from port 1 (A) to 3 (T) until the setpoint pressure is reached.
The valve is also usable as 2-way proportional pressure reducing valve (after consulting WEBER-HYDRAULIK ValveTech). However, the third port (T) may not be closed. To achieve optimal resolution, there are numerous pressure ranges available. The valve has a fast, accurate and low-vibration response. At just about 0.3 bar, the adjustable static minimum pressure is very low. Any functionally relevant components are hardened and polished. The leakage values are extremely low.
The valve is also available in a variety of sandwich- or in-line bodies and mounting plates.
The valve is available in degressive versions.
