Solenoid operated directional control valves are mainly used for changing direction of movement hydraulic actuators. Depending on the various spool types and their position, various kinds of movement can be effected in a hydraulic circuits. These valves are most common for industrial systems such as machine tools, hydraulic presses and SPMs but are also used in mobile hydraulic systems.
4/2-way spool valve, detented: 2 solenoids and 2 spool positions. With the solenoids deenergised the spool remains in the last switched position.
4/2-way spool valve, spring offset: 1 solenoid and 2 spool positions. With the solenoid deenergised the spool returns to the offset position.
4/3-way spool valve, spring centered: 2 solenoids and 3 spool positions. With the solenoids deenergised the spool returns to the center position.
Low leakage and long product life due to precise fitment of spools. The spools are made from heat treated steel with a cast body featuring an automotive paint coat for better appearance and protection from the elements. These are Direct operated solenoid valves with a 4 port and 5 chamber design. They can be spool detented or with spring reset.
