There are two cam operated 3/2 DCV which are called “limit valves” to operate this 4/2 DCV. • When a limit valve is pressed, fluid flows to the connected pilot and hence the spool of 4/2 DCV shifts to other position. • The piston rod, while reciprocating, actuates these limit valves, which intern actuates 4/2 DCV.
