What is the reason for the forced sealing of stainless steel forged steel valves?

The reason why the stainless steel forged steel valve adopts the forced sealing is that when the stainless steel forged steel valve is closed, the external force is forced to press the ram to the valve seat to ensure the sealing of the sealing surface. Stainless steel forged steel valves should generally be installed horizontally in the pipeline. When the gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the ram is pressed against the valve seat on the other side by the medium pressure to ensure the sealing of the sealing surface, which is self-sealing.
