In 4/3-way DIRECTIONAL VALVES the centre position of the CONTROL spool is the neutral position. The change-over to one of the operating positions "a" or "b" is done by moving the operating pin lever (5) in such a manner that its acts on the CONTROL spool (2) so as to clear corresponding flow ways and establish relevant links between ports, A, B, P, and ceasing to apply force to the CONTROL mechanism (3), the return spring (4) push the CONTROL spool into the neutral are two types of operation:1/ With CONTROL spool not held in the operating position (the CONTROL spool returns to neutral position on ceasing to apply force to the CONTROL mechanism - type ).
