For non-vertical stem type valves, if the valve is opened, the stem will not move upward. The stem is screwed into the dish. When the handwheel on the valve stem rotates, the disc moves up or down along the valve stem on the thread, while the valve stem r

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.

In a system with irregular changes in high temperature, the gate valve will leak due to the load in the valve end pipe.

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

Good sealing performance improves the reliability of the system. The friction resistance is small, the opening and closing is forceful and flexible. It has a long service life and can be switched repeatedly. High pressure and high temperature resistance,

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

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.

The ball valve is durable, performs well after many cycles, and is reliable, and can be safely closed even after long periods of non-use. These qualities make them an excellent choice for shut-off applications where they are generally more popular than ga

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.

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 valve seat of the gate valve is parallel to the flow direction of the medium, so there is less erosion of the valve seat when the valve is opened. This also makes the globe valve a good throttle valve. The disadvantage is that due to its design, there

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

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

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 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
