The manual gate valve is operated by a simple handwheel to raise the valve stem and gate. When closed, the gate rests on a seat ring, both of which are specially treated to provide a reliable closure.

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.

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

In the shut-off valve, the flow of water is controlled by a movable mandrel, and the flow of water is restricted by lowering the mandrel to a fixed valve seat.

Our company can also provide customized valve services according to your requirements. Feel free to contact us for more information or to request a complete product category.

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.

You can expect the service life of the shut-off valve to be approximately 10 to 25 years, with an average of 20 years. However, if they are not "exercise" once a year or two years, then when you really need to close the valve for a pipeline emer

We produce cast iron wafer butterfly valves, with hand lever or worm gear Operator. Our Butterfly Valves are widely used in drinking water system, sewage system, fire-fighting system. Butterfly Valves can produce from size DN40 to DN2400.

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

The gate valve is a two-way sealed valve. The valve body-bonnet joint and packing chamber are sealed with non-asbestos gaskets and packing to ensure a long service life.

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

Industrial applications such as power generation, mining and chemical industries use gate valve. What makes it useful is that the design limits flow barriers. In addition, there is minimal pressure drop. This kind of valve can also be used when the pressu

The easy operation, maintenance and versatility of the ball valve make it widely used in industry. This high-quality ball valve will be an excellent choice for shut-off and control applications.

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

The gate valve cannot be opened and closed quickly. To fully open or close the wheel or gearbox actuator, the shaft should be rotated to the number of fully open revolutions. The number of full-open revolutions is equal to the pitch.
