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

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 valve is made of stainless steel and the material is 304/316. They can be used to control the flow of water, oil and gas, including various corrosive and radioactive media.

Gate valves are very reliable in shutting off the water supply. They are usually used as shut-off valves for the main water supply line and branch water supply lines, although ball valves are gradually becoming more and more popular in these applications.

Butterfly valves can be used in the shipbuilding industry, water supply and drainage, fire fighting, shipbuilding, water treatment and other systems.

The gate valve is composed of three main parts: the valve body, the valve cover and the valve trim. The body is generally connected with other equipment through flange, thread or welding connection. The engine cover containing the moving parts is usually

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.

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.

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

Its working principle is to lift or press a rectangular or circular gate connected by the valve stem to the fluid path by rotating the handle wheel clockwise and counterclockwise.
