Electro-hydraulic Proportional Throttle Valve

Throttle valve is a valve that controls the flow of fluid by changing the throttle section or length. If a throttle valve and a check valve are connected in parallel, they can be combined into a check throttle valve.

Throttle valve and one-way throttle valve are simple flow control valves. In the quantitative pump Hydraulic System, throttle valve and overflow valve cooperate to form three kinds of throttle and speed regulating systems, namely, oil inlet throttle and speed regulating system, oil return throttle and speed regulating system and bypass throttle and speed regulating system.

The throttle valve has no negative flow feedback function and can not compensate the speed instability caused by the load change. It is generally only used in the situation where the load change is not large or the speed stability is not high.
