What is an electric gate valve

The purpose and use of both gate and butterfly valves are same. The difference between the both valves lies in shape, size and operation. Butterfly valves are lighter than gate valves, so for the big sizes it is convenient to install and operate butterfly valve because it is lighter and compact in compare to gate valves.

Gate valves either allow or bar the passage of hydraulic fluid, and globe valves adjust the flow of hydraulic fluid between fully on and fully off. Gate valves are plate-like, and globe valves are circular.

The structure classification of electric gate valve: gate valve is generally composed of valve stem, valve body, bonnet, gate plate, driving device and other parts (fasteners, stem nut, sealing packing). The structure is introduced one by one below: Gate valve stem press The movement form is divided into the open rod (lifting shaft) and the dark rod (rotating shaft). Therefore, the gate valve is divided into two types: the open rod gate valve and the dark rod gate valve.
