Configurable for internal or external pilot drains and options for pilot pressure reducing pilot chocks and main. However because this is a spool valve there will be some leakage between ports so the a and b lines may still be subject to experiencing different pressures and facilitating cylinder creep. When solenoid magnet a is energized the spool is pulled to left connecting the ports p to a and the ports b to tb when solenoid b is energized the spool is pulled to right connecting p to b and a to ta.

The simplest directional control valve is the 2 way valve. P is pressure inlet a and b are utilization ports ta and tb are return ports. Size10 5 90kgs 12 98lbs related parts. Change direction of fluid flow.
