Manual Gate Valve(Manually Operated Gate Valve)

Manual gate valve is a hand-operated valve. By turning the handwheel manually, the gate valve is opened or closed, allowing the medium to circulate or cut off. The manual gate valve provides an accurate flow release or blocking function, allowing the staff to easily achieve the purpose of flow control.

Automatic Gate Valve

When the gate valve is equipped with an automatic gate valve actuator, the safety and production efficiency of the system can be greatly improved.

Automatic gate valves can be divided into electric gate valves and pneumatic gate valves.

Electric Gate Valve(Electrically Actuated Gate Valve)

Electric gate valve means that the electric gate valve actuator drive by AC/DC current and signals reception/feedback to opens or closes the valve. Since the opening and closing speed of the electric gate valve is slow, the risk of water hammer effect is greatly reduced. With the development of science and technology, people’s demand for electric gate valves is increasing day by day.

Pneumatic Gate Valve(Air Operated Gate Valve)

Pneumatic gate valve refers to the use of compressed air to drive the pneumatic gate valve actuator to open or close the valve. Because the pneumatic gate valve does not need electricity to open or close, it is safe and reliable.

Non-Rising Stem Gate Valve

Non-rising stem gate valve means when we rotate the handwheel, and we can’t see the valve stem. When the medium circulates, the valve stem and the valve plate will be exposed to the medium.
