Electric Actuated Gate Valve

Electric water seal gate valve opens and closes the valve by rising and falling the gate. Its gate perpendicular to the way of fluid, and the size of the channel can be changed by altering the relative position between gate and valve seat.

Classification of operating temperature

(1) Ultralow temperature valve: apply to the valve which medium operating temperature t<-100℃. 

(2) Low temperature valve: apply to the valve which medium operating temperature -100℃≤t≤-40℃.

(3) Normal temperature valve: apply to the valve which medium operating temperature -40℃≤t≤120℃.  

(4) Intermediate temperature valve: apply to the valve which medium operating temperature 120℃.

(5) High temperature valve: apply to the valve which medium operating temperature t>450℃.
