ZXPⅡ Pneumatic Diaphragm Low-noise Single Seat Control Valve

In the working place, there are three kinds of noise: mechanical noise, fluid-dynamic noise, aerodynamic noise. When the noise becomes excessive, you would select a low-noise control valve. It is especially suitable for the working place, which is high dropout or after shorting.
