Solenoid Hydraulic Directional Control Valve

Electric hydraulic valve or directional control valve is used for stop, start and control direction of hydraulic fluid flow under pressure. Hydraulic directional valves are produced in spool and piston or rotary models. Rotary models are used up to 70 times less due to pressure limitation. Are placed.

The efficiency of the directional control hydraulic valves depends on the following:

Dynamic power range (maximum flow and pressure performance)

Static strength range (adhesion force that can occur between the spool and the body)

Current resistance (internal resistance for example pressure drop)

Leakage (only on Spool models)

Switching time (time between force operation and completion of control element operation)

The operation of the hydraulic valve is defined by the number of working ports (except control ports) and the number of spool positions. Directional control valve, which includes at least two spool positions and two working ports.

The most common control models are 3.4 valves, which means four working ports and three spool positions according to DIN ISO 1219 standard.
