Copper&Bronze/Stainless Steel/Steel material has longer service life for your pipes&vessel. 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 t
