The working principle of the stop valve is the vertical movement of the valve disc away from the valve seat. So when the valve is closed, it will cause the space between the disc and the seat ring to close. This is why these valves are used to start, stop

When the handle wheel is turned clockwise, steam and steam move down through the fluid flow, and the gate is squeezed between the two valve seats, so that no fluid leakage occurs when the valve is completely closed.

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

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 plug or disc is an important part of the valve. It is connected to the valve stem and can be used for throttling.

Simple structure, convenient operation, convenient installation, good sealing performance, long service life, high reliability, good interchangeability of parts, and cost saving.

The valve cage is a part of the valve, which surrounds the valve plug and is located in the valve body. The valve cage is the main component that determines the fluid flow in the valve. As the stopper moves, more cage openings are exposed and the flow rat

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

The gate valve is a valve that completely restricts the flow of fluid and provides a full-diameter valve without changing the direction. The valve disc is appropriately called a gate here and is moved into the fluid at right angles by a threaded shaft wor

Gate valves are widely used in all types of applications, suitable for above-ground and underground installations. Especially for underground installations, it is important to choose the correct type of valve to avoid high replacement costs.

The gate valve is designed for fully open or fully closed service. They are installed in the pipeline as isolation valves and should not be used as control or regulating valves.

This is the connection from the actuator to the valve, which provides the driving force. The stem of the actuator control valve can be smooth, and the stem of the manual control valve can be threaded.

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

The gate valve allows the user to control the flow pressure instead of simply closing or opening it. Compared with ball valves, gate valves provide users with more control over water flow and pressure, but they cannot let users choose to stop the water fl

The pressure-sealed gate valve is designed in accordance with API 600, suitable for high temperature and high pressure working conditions, and is widely used in nuclear power plants and thermal power plants. Compared with bolted bonnet joint valves, they
