Proportional Pressure Control Valve EPDRD3-04
The 3-way proportional pressure control valve EPDRD3 size 04, is a direct operated valve in spool design that is suitable as a pilot valve. It reduces an inlets’ pressure to a lower consumer pressure. The consumer pressure is proportionally adjustable to the solenoid current. The valve is particularly suitable for controlling relatively large pilot flow rates (e.g. of variable delivery pumps). However, due to the very small leakage oil values, it is also widely used in low-loss small hydraulic systems (e.g. clamping or braking systems).
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 or honed.The leakage values are extremely low.
The valve is buit in a compact design and is also available in a variety of in-line bodies and mounting plates in nominal size 4 (NG 4, ISO 4401) and nominal size 6 (NG 6, DIN 24340 A06).
The valve is also available in degressive versions.
