The SZRQM series intelligent electric regulating valve is a pressure balanced regulating valve. Equipped with RQM series intelligent electric actuators, it has a compact overall structure, light weight, good stability, and high protection level. Therefore, it is widely used in automatic control systems such as large thermal power plants, chemical plants, water and sewage treatment, natural gas oil fields, steel plants, etc.
