Cartridge Solenoid Directional Valves

Cartridge Solenoid Directional Valves's function is represented with an ISO standard hydraulic symbol that characterizes the function that the valve performs.  In our many product pages, you can find many unusual valves with very peculiar and complex hydraulic symbols that appear to contain an entire small hydraulic circuit.
Cartridge Solenoid Valves can be thought of as "bodyless" - valves without an integral housing - because they consist of only the internal moving elements of the valves. After a cartridge is inserted into a cavity, such as a manifold with appropriate flow passageways, the resulting valve performs like any conventional valve. Slip-in cartridges are held in the cavity by a cover plate. screw-in-type cartridges mate with threads in the cavity. Another type of insertable cartridge has circumferential grooves.
