Product overview


Electric single-seat regulating valve adopts fluid pressure imbalance spool structure, special single-seat spool and cage top guided valve inner combination structure, so that it has the characteristics of single-seat regulating valve, while the dynamic stability of sleeve regulating valve, cage guide sleeve also plays the role of anti-erosion, anti-aircraft and so on; The quick-discharge valve inner assembly is very convenient for updating the inner parts. Suitable for high pressure difference, high temperature and other harsh conditions, especially suitable for all kinds of slurry, polymer and high temperature media. 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 control systems.
