When the medium pressure is low, the sealing force of the metal sealing surface is insufficient to achieve a satisfactory seal. Conversely, when the medium pressure is high, if the sealing surface is not lubricated with system medium or foreign medium, frequent opening and closing may cause the sealing surface to wear excessively. Another disadvantage is that the circular ram that moves laterally on the circular flow path is more sensitive to flow control only when it is at 50% of the valve closed position. Moreover, the ram produces severe vibrations when the high speed and high density media flow is broken. It can also be used for throttling if the valve seat is made into a V-shaped port and is closely guided to the shutter.
