Product Description
Product Introduction
Proportional valve is a new type of hydraulic control device. In the ordinary pressure valve, flow valve and directional valve, the proportion of electromagnet instead of the original control part, according to the input electrical signal continuously, in proportion to the flow of oil pressure, flow or direction for long-distance control. Proportional valves are generally pressure compensated, and the output pressure and flow can be unaffected by load changes.

Woring principle
With the solenoids (4) de-energised, the control spool (2) is held in the central position by compression springs (3). Direct actuation of the control spool (2) by energising a proportional solenoid.E.g. controlling of solenoid "b" (4).The control spool (2) is moved to the left in proportion to the electrical input signal.Connection form P to A and B to T via orifice-like cross sections with progressive flow characteristics. De-energisation of the solenoid (4).The control spool (2) is returned to the central position by compression spring (3).
