Boiler feed pump minimum circulating flow control valve

The two-position switch action is mainly used in the water supply system of large generator sets. It is an important equipment to prevent the vaporization of the boiler feed pump and one of the key regulating valves in the power plant. It is also commonly used in petroleum, chemical and other high-pressure differential two-position control occasions.
