Here, the throttle ( measuring throttle ) in the form of a 2/2-way or 4/2-way valve is actuated by a proportional solenoid. An additional function is the maximum pressure protection. Die Richtung von Fluidströmen in der Hydraulik und Pneumatik wird im Allgemeinen durch Pfeile in den entsprechenden Fluidelementen, Leitungen bzw. The valves can also handle large amounts of flow with accuracy. GoTo Proportional Valves – Ships in 10 business days. Some experience with the directional control valve symbol has already been gained. Valves of type P4WEH are hydraulically piloted directional spool valves with proportional coil and in plate-mounted form. These open-loop, single-stage valves can be used for direct control of pressure in low flow systems, or for pilot control of larger pressure controls, and for such applications as pressure-controlled pumps.
