What is Gate Valve?

The gate valve is a valve that can only be fully open and fully closed. There is an opening and closing valve plate in the gate valve. When the handwheel is turned, the valve plate will make a linear movement upward or downward, thereby opening or closing, allowing the medium to circulate or cut off.

Due to the advantage that the gate valve is not easy to be blocked, the gate valve is very suitable for the circulation of viscous materials such as mud, such as syrup, cement, garbage disposal, grease and so on. It is widely used in HVAC, paper and pulp, Sugar & ethanol, cement plant, chemical industry, food industry, etc.

COVNA gate valves can customize different styles of gate valves for you, such as low temperature, high temperature, and high pressure according to the requirements of your different working conditions. At the same time, COVNA gate valve can be made of different materials, which can be better used in your industry.

COVNA as the top gate valve manufacturer in China, we are willing to help you select the right gate valve which could provide you the better performance.

Gate Valve Types By Actuator

As a one-stop valve and actuator solution provider, COVNA also could offer valve with actuator for you to meet your different applictaions. To help your automation easier.

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.

Gate Valve Types By Material

COVNA manufactures gate valves in WCB and stainless steel material for your choice to meet your different requirements. Quality material with the material test, eco-friendly and food safe.

Stainless Steel Gate Valves

The stainless steel gate valve may be made of stainless steel 304, stainless steel 316 or stainless steel 316L. Its unique durability and corrosion resistance are favored by the majority of users, and thus it is widely used.
The stainless steel used in the COVNA gate valve has passed the material test report and is 100% hygienic and usable.

Carbon Steel Gate Valves(WCB Gate Valves)

Carbon steel gate valve root processing technology can be divided into forged steel gate valves and cast steel gate valves. The advantage of forged steel gate valve includes that it can withstand high pressure and is more suitable for heavy industry. The advantage of cast steel gate valve including that can be customized into various types according to your requirements.

Gate Valves Types By Connection

Flanged Gate Valves

Flanged gate valves are gate valves with flange connections at both ends. Flanged gate valves are currently the most commonly used connection method in industrial valves. At the same time, the flange gate valve is also the best-selling valve in COVNA.
Flanged gate valve uses nuts and bolts to fix the pipe, which makes installation easier.
Flanged gate valve can be divided into ANSI, JIS, DIN, GB standards according to the link standard to meet your requirements of different working conditions.

Gate Valves Types By Stem

Rising Stem Gate Valve

Rising stem gate valve means that when you turn the handwheel, you can clearly see the valve stem rising or falling in a straight line. When the medium is circulating, the valve stem will not touch the medium. Rising stem gate valve can be installed with an actuator, from a manual gate valve to an automated gate valve.

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.

Metal Seated Gate Valves

Metal seated gate valve has a metal seat wedge, which is mainly used to isolate the flow in pipes or equipment. It has excellent durability and long service life.

Resilient Seated Gate Valve

Resilient seated gate valve is a gate valve made of cast iron with soft seals inside to reduce friction and prolong the service life of the valve.
