Functional features of multifunctional electro-hydraulic valve:

(1) can be multi-section open, closed, eliminate water blow. For a general oil system, the impact pressure of the water hammer often exceeds the maximum pressure limit of the relevant equipment on the pipeline, sometimes even up to more than 3 times. This is enough to cause the pump, valve, flowmeter, pressure gauge, filter and other equipment on the pipeline to suffer different degrees of damage, leading to shortened life, action error, and serious paralysis of the operation. DYF TYPE MULTI-FUNCTION ELECTRO-HYDRAULIC VALVE IS THE IDEAL valve to eliminate water blow, its opening and closing time is continuously adjustable (from 2s to infinite). According to the actual use, it is known that under normal circumstances, when the valve opening time is adjusted to about 2s, and the valve closing time is adjusted to 4s~5s, the water hammer phenomenon can be basically eliminated.

(2) Controllable adjustment to achieve constant current. Normally open and normally closed two solenoid valves are controlled by the controller, and the power is off. The opening of the electro-hydraulic valve can be adjusted arbitrarily, so that the output flow can be changed according to the demand. If a constant flow is needed, as long as the flow signal is fed back to the controller, the controller can adjust the two solenoid valves to keep the output flow constant.

(3) with medium pressure, opening pressure is small

(4) Long service life.

(5) Simple control loop, easy maintenance.

(6) Sealing without packing, sealing is reliable.

(7) It can be installed horizontally and vertically, with a wide range of applications.
