Product Details

ZXPII/ZXMII  Series of of Pneumatic/Electric Intelligent Low-noise Control Valve are State Torch Program,and have multiple state patents. It uses modular design and impact structure. Through the special symmetric holes on the valve trim, it could reduce the noise and pressure, thereby preventing from flashing and cavitation,make it applicable for high pressure difference and low noise conditions to meet customers requirements. Double-sides valve seat and compressing connection of the valve body,greatly enhance the sealing grade and service life of the valve lead, which make it easy to repair and greatly increase the general performance of the regulating valve.
