Product details

Electric double seat steam pressure reducing valve

电动双阀座蒸汽减压阀

Working principle and purpose of the product:

The electric pressure reducing valve achieves the purpose of controlling the pressure after the pressure reducing valve by adjusting the dynamic pressure head of the primary side fluid. A pressure reduction ratio of 0.6 is more suitable for this series of products.
This product is mainly used for steam pipelines to regulate pressure. Widely used in industries such as cogeneration, textiles, printing and dyeing, petrochemicals, and sugar production.

Product Structure Features:

Y945H/Y electric double seat steam pressure reducing valveIt is mainly composed of valve body, valve seat, valve disc and other parts, and adopts a structure of double valve seat and double cone valve disc. Adopting a pressure balanced valve disc, the pressure can be adjusted by lifting and lowering the valve disc, and ZKZ-BC or other types of linear electric actuators can be used for remote control and automatic control. Electric stepless adjustment, stable secondary pressure, high control accuracy. Easy to operate, only need to modify the secondary pressure setting through the controller. Smooth operation
