The valve is generally robust, has a short opening height, is simple to make, requires little maintenance, and can withstand high pressure in addition to low and medium pressure. This is due to the limited amount of friction between the sealing surfaces during the opening and closing operation. Its closing mechanism relies on the pressure exerted by the valve bar, which causes the disc sealing surface and valve seat sealing surface to close and stop media flow.
