Stainless Steel Pneumatic Diaphragm Regulating Valve

Stainless steel pneumatic diaphragm regulating valve body and valve cover are made of stainless steel materials with high corrosion resistance and better sealing performance. The pneumatic actuator uses compressed air or gas as a power source, by regulating the air source pressure to control the position of the valve core, so as to achieve accurate control of media flow, pressure and temperature parameters. As the core component of the control valve, the film has good sealing performance and fast response characteristics, and can achieve high precision control.
