ZXM Pneumatic Diaphragm Cage Control Valve

ZXM Pneumatic Diaphragm Cage Control Valve is a pressure-balanced valve, equipped with a multi-spring actuator. It plays a very important role in fluid handling system and features high flow capacity, low pressure drop loss, great pressure drop allowable, compact structure, light weight, low noise level, and good stability.It is used to regulate and control the pressure, flow and liquid level of gas, fluid, or steam media, and is particularly applied for occasions where the pressure drop is large and the demand for leakage is low.
