Shut-off valve
一. Product overview
The cut-off valve is used to cut off the flow of the medium. The stem axis of the cut-off valve is perpendicular to the sealing surface of the valve seat, and it is broken by driving the valve core up and down. The stop valve can be used in most media flow systems. Various types of shut-off valves have been developed to meet various uses in petrochemical, electric power, metallurgy, urban construction, chemical and other sectors.
2. Product features
1. Once the shut-off valve is in the open state, there will be no contact between its valve seat and the sealing surface of the disc, and it has a very reliable cut-off action, so its sealing surface has less mechanical wear.
2. The opening height is generally only 1/4 of the diameter of the valve seat passage, so it is much smaller than the gate valve.
3. Usually there is only one sealing surface on the valve body and disc, so the manufacturing process is relatively good and easy to maintain. However, the shortcomings of the globe valve cannot be ignored. The main disadvantage is that the coefficient of flow resistance is relatively large, which causes pressure loss, especially in hydraulic devices, this pressure loss is particularly obvious.
