Product Description

45H lever pressure reducing valve is mainly composed of valve body, seat, valve disc and other parts, using double seat, double cone valve disc structure. The pressure balance type valve disc, lifting adjustment. The adjusting mechanism adopts the pole type, can be equipped with DKJ type or other type angular travel electric actuator, to achieve remote control and automatic control.
The pressure reduction of Y45H lever pressure reducing valve is more suitable than that of 0.6.
Y45H lever type pressure reducing valve is mainly used for steam pipeline, regulating pressure. It is widely used in cogeneration, textile, printing and dyeing, petrochemical, sugar and other industries.
