Proportional Pressure Control Valve

The direct operated 3-way proportional pressure control valve size 04 reduces an inlet's pressure to a lower consumer pressure. The consumer pressure is proportionally adjustable to the solenoid current.

Oil keeps flowing from port P to A until the setpoint pressure is reached, then the valve closes. The valve only opens up again from P to 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 A to T until the setpoint pressure is reached. The valve can also be used purely as a pressure reducer (2-way function). However, the third port (T) may not be closed.

Optimal adaptation to the requirements is possible through a variety of pressure ranges.
The valve has a fast and precise control behaviour that remains stable even when vibration is present.
At just about 0.3 bar, the adjustable static minimum pressure is very low. Any functionally relevant components are hardened and polished or honed. Although it is a piston-sleeve design, the leakage values are still extremely low.
