Cage guided globe control valve

Overview of Cage guided globe control valve

Cage guided globe control valve is clearance fit with the valve disc, and a plurality of throttling windows are opened on the sleeve. The shape of the window determines the flow characteristics of the regulating valve, and the area of the window affects the flow coefficient CV of the regulating valve. The valve seat adopts a self centering non threaded snap in structure. The conical sealing surface on the valve seat cooperates with the conical sealing surface on the valve disc to form a cut-off sealing pair to ensure that the valve is tightly closed when the valve disc is pressed on the valve seat. The valve seat diameter affects the flow coefficient CV of the regulating valve. There are symmetrically distributed balance holes parallel to the axial direction on the valve disc to connect the chambers at the upper and lower end faces of the valve disc. In this way, most of the forces of the medium in the valve acting on the axial direction of the valve disc offset each other, and the unbalanced force generated by the medium on the valve stem is very small

Features of Cage guided globe control valve

1. The balanced valve core is adopted, with small unbalanced force, large allowable differential pressure and stable operation.

2. The valve core has a large guiding surface, which can improve the oscillation caused by eddy current and impact.

3. Compared with ordinary single and double seat regulating valves, the noise is reduced by about 10dB.

4. The utility model has the advantages of simple structure and convenient assembly, disassembly and maintenance.
