What is a throttle valve?

A throttle valve is a valve that controls fluid flow by changing the throttle section or throttle length. A one-way throttle valve can be combined by connecting the throttle valve and the one-way valve in parallel. Throttle valve and one-way throttle valve are simple flow control valves. In the quantitative pump hydraulic system, the throttle valve and the overflow valve cooperate to form three kinds of throttling speed regulation systems, that is, throttling and speed regulation of the oil inlet circuit. system, oil return throttling speed regulating system and bypass throttling speed regulating system. The throttle valve has no flow negative feedback function and cannot compensate the speed instability caused by the load change. It is generally only used in occasions where the load change is small or the speed stability is not high.
