A rotary spool valve consists of a rotating spool which aligns with ports in stationary valve casing, so that fluid is directed to required port.
Pressure port (P), Actuator port (A) and Receiver port (R) are the ports in casing. The port "P‟ is a pressure port though which pressurized fluid is coming in the valve. "R‟ port is the port through which used fluid is returning to the Receiver.
From fig (a) which indicate first position of the rotary spool type 3/2 DCV connects port P to port A While receiver port R remains closed. In second position shown in fig (b) of rotary spool type 3/2 DCV port A is connected to port R while port P remained closed.
