HTW electric telescopic type regulating valve is a low noise, comprising a sleeve oriented anti cavitation valve sleeve, due to the multistage (II or III) can effectively control the fluid velocity, it can eliminate the noise of fluid pressure differential gas or steam, but also can effectively prevent fluid cavitation pressure differential destruction. The valve is widely used, long service life, convenient repair, is a kind of air defense, low noise, stable control fluid control valve.

Two, structure diagram as follows:
