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.

Eigenschaften:

-Forged angle type, Z type valve body
– The fluid is depressurized step by step, the direction of the fluid is continuously changed, the flow resistance is increased, the flow rate is controlled, and the fluid is prevented from cavitation damage. The allowable pressure difference in the interval is 25MPa
-Multi-stage throttling design
-The throttling surface is separated from the sealing surface, and the surface is hardened. -The solid particle anti-seize design
– Common parts, good interchangeability
