ZMAS ZMBS Pneumatic Diaphragm Angle(Single-stage、Multi-stage) Control Valve

ZMAS ZMBS Pneumatic Diaphragm Angle(Single-stage、Multi-stage) Control Valve is equipped with pneumatic Actuator。 It is widely used to control the pressure and flux of liquid medium (including gases, liquid, steam and other media). Its body is adopted high-temperature and high pressure of the shell material. What is more, many ports in the body are fire-resistant, anticorrosion. It can minimize noise by Single-stage (Multi-stage) Control. It also has the advantages of compact structure, lightweight, low noise, large allowable pressure differential, easy disassembly and so on.
