Boiler continuous blowdown control valve

Mainly used in power plants to continuously remove part of the dissolved salt in boiler water. It is one of the key valves in power plants to control saturated water with high pressure difference. It can also be used in the petroleum and chemical industries to control the flow rate of high pressure drop saturated liquid.
