Globe Control Valve

Pneumatic Unbalanced Shut Off Control Valve

Unbalanced shut-off control valve uses a top-guided and pressure-unbalanced spool for applications where the differential pressure is small. The surface of the valve core and the valve seat is welded with hard alloy to ensure the long-term stability of the valve. For the cutting of high medium temperature and large differential pressure, we have specially designed a double-valve pressure relief shut-off valve. This type of trim has a double-valve construction and a flow-off design.
