How it works

A directional control valve sets the oil path between the pump, the actuator and the tank. As the spool moves inside the body, ports connect or close, and a cylinder or motor extends, retracts or holds. The spool type decides whether the ports are closed or open to tank in the centre position.

Selection and maintenance

When choosing, check the mounting pattern, spool type, coil voltage and connector, because one different letter in the code can change how the circuit behaves. A sticking spool usually comes from dirty oil, and a burnt coil from the wrong voltage or a stuck spool. Before replacing a valve, also check the circuit filter and the oil.
