ZXM REGULATOR is a pressure balance type regulating valve which consists of multi-Spring diaphragm pneumatic actuator and low flow resistance sleeve valve.

ZXM REGULATOR has the advantages of 1.with balanced valve core,the unbalance force is small and allow the the large pressure difference,2.Valve core guide is large, it can improve the eddy currents and oscillations caused by the impact and reduce valve damage. 3.Simple structure, light weight,easy assembly,disassembly and maintenance. 4.with little noise and large flow .

This regulator is designed and manufactured according to the standard of AMSE /API /BS/ DIN/GB.And it's widely used in the precise control of gas, liquid and steam medium,the process parameters such as pressure, flow rate, temperature and liquid level can be easily kept in a set value.Especially suitable for large flow, large pressure difference and the leakage less demanding applications.
