Valves (DDV). To increase the spool actuation force, the main spool of pilot operated valves is operated hydraulically by a pilot valve. By hydraulically amplifying the electrical command signal, pilot operated valves can reach very high spool actuation forces and thus be built up to very large rated flows.

Spool Valves, 4-Way, 5-Port The 4-way spool valve can be controlled by using two operators, one on each end or by a spring return and a single operator. The flow path when actuated at the 14 end of the valve is from port 1 to port 4 and from port 2 to port 3. Port 5 is blocked. When the valve is actuated from the 1 2 end, the flow path
