Product Description

Y945H Electric Double Seat Steam Pressure Reducing Valve

Product Description

Brief Introduction.

This series reducing valve mainly composed of valve body, valve seat and valve flap. It adopts the structure of double valve seat and double cone valve flap. It adopts pressure balancing valve flap. Realize remote control and auto control through valve flap elevation to adjust the pressure, ZKZ-BC or other type straight travel electric activator can be equipped. The decompression ratio of this series product is best to be 0.6. The product is mainly applied on steam piping, to reduce and regulate the pressure. It is widely used in combined heat and power generation, spinning, printing and dyeing, petrochemistry and sugar-making industries.
