Hydraulic Proportional Valve
Hydraulic Proportional Valve is electronically actuated valves in which the output is changed at the same ration as inlet valve. It is used to controls the speed of a cylinder or hydraulic motor. Control electronics & proportionally designed solenoids are required for actuation. Hydraulic Proportional Valve has low cost designs without spool feedback for manual & open loop control applications. It can be direct or pilot operated. Moreover, this proportional directional valve work well in different closed loop applications.
