Product Introduction

Y945H electric pressure reducing valve

Related model: Y945H-16/25/40/64/100/160

Structural features and uses of Y945H electric pressure reducing valve:

This series of pressure reducing valves are mainly composed of valve body, valve seat, valve disc and other parts, adopting the structure of double valve seat and double cone valve disc. It adopts pressure-balanced disc, and adjusts the pressure through the elevation of the disc. ZKZ-BC or other linear electric actuators can be used to realize remote control and automatic control.

It is more appropriate to use 0.6 for the decompression ratio of this series of products.

This product is mainly used in steam pipelines to adjust pressure. It is widely used in industries such as cogeneration, textile, printing and dyeing, petrochemical, and sugar making.

Structural features of electric pressure reducing valve Y945H:

The electric double-seat pressure reducing valve Y945H is equipped with a throttle hole cover, which increases the pressure reduction range, and at the same time avoids the direct injection of the temperature reduction water on the valve body, which protects the valve body. It is mainly composed of valve body, valve seat, valve clack, valve cover and other parts. The electric pressure reducing valve Y945H adopts the structure of double valve seat and double cone valve disc, which increases the flow area and adjustable ratio. It adopts pressure-balanced disc, and adjusts the pressure through the elevation of the disc. ZKZ-BC or other linear electric actuators can be used to realize remote control and automatic control. Electric stepless adjustment, stable secondary pressure, high control accuracy. The operation is simple, only need to modify the secondary pressure setting through the controller. Smooth operation and long service life.
