A shut-off valve refers to a valve where the closing element (disc) moves along the centerline of the valve seat.
According to the movement of the valve disc, the change in the valve seat opening is directly proportional to the valve disc stroke.
Due to the relatively short opening or closing stroke of the valve stem and the highly reliable cut-off function,
as well as the proportional relationship between the change of the valve seat opening and the stroke of the valve disc,
this type of valve is very suitable for regulating flow.
Therefore, this type of valve is very suitable for use as a shut-off or regulating and throttling device.
Advantages:
(l) During the opening and closing process, the friction between the valve disc and the valve body sealing surface is smaller than that of the gate valve, so it is wear-resistant
(2) The opening height is generally only 1/4 of the diameter of the valve seat channel, 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 drawbacks of shut-off valves cannot be ignored.
The main drawback is that the flow resistance coefficient is relatively large,
resulting in pressure loss, especially in hydraulic devices, which is particularly significant.
