Boiler feed pump minimum circulating flow control valves

The two-position action of the switch 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 water pump, and it is also one of the key adjustments in the power plant. It is also commonly used in petroleum, chemical and other high-pressure differential two-position control occasions.
