Easy to operate | Electric gate valve | Wholesale agent

The electric gate valve has a manual actual operation organization on the top and bottom of the electric installation. When there is no switching power supply, manual operation can be used to open and close the valve. When the handle rotates clockwise, the gate valve is closed. When rotating in the opposite direction, open the gate valve and start the ball valve.

COVNA Multi Turn Actuator Electric Gate Valve

A  Electric Gate Valve, also known as a sluice valve, is a valve that opens by lifting a barrier (gate) out of the path of the fluid. Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully opened.

COVNA Multi Turn Actuator Electric Gate Valve

Multi-turn electric gate valve

for fully open and fully close. With features of high flow rates and remote control. Widely used for paper and pulp, power plant, chemical industry, iron industry and so on. Gate valve available in ANSI, JIS, DIN, GB standard. Electric knife gate valve also available for your project!
As an electric actuator valve manufacturer, we manufacture ball valves, butterfly valves, gate valves, globe valves with electric actuators for you.

Multi-turn electric gate valve

Cast Steel WCB Flange Electric Gate Valve

  1. Simple structure, easy to manufacture and maintain
  2. Small working stroke and short opening and closing time
  3. Good sealing performance, small friction between sealing surfaces and long life
  4. In the process of opening and closing, the friction of the sealing surface is smaller than that of the gate valve, which is wear-resistant
  5. usually only one sealing surface, good manufacturing process, easy to maintain

Features of electric gate valve

1. The structure is compact, the design is reasonable, the valve rigidity is good, the passage is smooth, and the flow resistance coefficient is small.
2. The sealing surface is made of stainless steel and hard alloy, which has a long service life.
3. Using flexible graphite packing plate, reliable sealing, light and flexible operation.
4. The driving mode is divided into manual, electric, pneumatic, gear transmission, and structural forms; elastic wedge single valve, rigid wedge single valve plate and double gate plate type.
5. It is widely used as the opening and closing device for connecting or cutting off the medium in the pipelines of petroleum, chemical, thermal power plants and other oil, water and steam pipelines.
6. It saves effort to open and close the gate valve.
7. The flow direction of the gate valve medium is not restricted, does not disturb the flow, and does not reduce the pressure

Frequently Asked Question

Do you have any question?

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.
