These shut-off valves must not be used for on/off service because it is impossible to achieve a tight seal. The disc in the valve can be completely removed from the flow path, or the flow path can be completely closed.

The gate valve can provide different discs or wedges. The range of the gate valve is usually determined by the type of wedge used.

We test every valve during the production process, and carry out quality control in all processes such as forging, processing, and assembly to ensure quality.

Gate valves are the most common type of valve in any processing plant. It is a linear motion valve used to start or stop fluid flow. In use, these valves are either in the fully open position or in the fully closed position. When the gate valve is fully o

The stop valve opens and closes the valve with the help of a plug-shaped disc, which is tightly fixed in the valve.

The closing function of gate valves is very good. They provide laminar flow with minimal pressure loss.

Forged steel gate valves are available in three bonnet designs. The first design is a bolted bonnet with male and female joints and spiral wound gaskets, made of F304/graphite. Ring joint gaskets are also available on request. The second design is a welde

Ball valves are often used for steam, water, oil, gas, air, and corrosive fluids. They can handle slurries and dusty dry fluids. The ball valve is not used for abrasive and fibrous materials, because it will damage the surface of the valve seat and valve

This kind of gate valve is more flexible, because its gate can move up or down, there is no obstacle to the flow of fluid or gas, thus ensuring less friction.

The valve seat is responsible for the movement of the valve gate. It can also help to further seal the flowing medium. For gate valves, there are two valve seats according to the type of gate. Take the wedge valve as an example, the valve seats on both si

Generally, gate valves are used to completely close the fluid flow in the pipeline, or to provide the full flow in the pipeline when fully opened. Therefore, it can be used in a fully closed or fully open position.

The sealing ring adopts seatback type, mortise type or directly vulcanized on the valve body. The sealing surface of the valve seat flange adopts an O-ring to cooperate with the pipe flange cone, and the sealing effect is good. It is easy to disassemble a

The assembly, start-up, and maintenance of gate valves require a lot of space.

Ball valves are more effective in forming tight seals and have higher reliability and life than gate valves, but they are more expensive. They are often used to shut down and control applications. Because the ball valve can be opened and closed instantane

In the 19th century, due to the increasing use of gate valves in industrial operations, their intensive development moved forward rapidly. Over time, the materials involved in manufacturing have been improved and modified to suit different applications.
