Manual Pressure Sealing Globe Valve

Forged steel self-sealing globe valves are valves in which the closing member (disc) moves along the center line of the seat. According to this form of movement of the valve disc, the change of the valve seat orifice is proportional to the valve disc stroke. Because the valve stem opening or closing stroke is relatively short, and has a very reliable cut-off function.
