SZRQM series intelligent electric regulating valve

Intelligent SZRQM regulating valve
SZRQM intelligent electric regulating valve introduction:
SZRQM series intelligent electric regulating valve is a pressure balance type regulating valve. With RQM series intelligent electric actuator, the overall structure is compact, light weight, good stability, high protection level. Therefore, it is widely used in large-scale thermal power plants, chemical plants, water treatment and sewage treatment, natural gas oil fields, iron and steel plants and other automatic regulation systems.
