Product Description

Product Description

Cage Guided Control Valves have large Cv value and excellent dynamic stability. It is suitable for heavy-duty services. Only a small operation force can achieve stability control due to the balanced fluid pressure structure on the plug. For those severe fluid conditions that cannot be covered by this series, please select Specs Valve multi-stage type Control Valves.
Features:

1. The third generation of S-type smooth casting body cavity gets greater circulation ability to reduce the initial investment, as it is now with more efficient average flow velocity by improving the second generation through CFD (Computational Fluid Dynamics)
2. In accordance with ASME, the valve body and the upper bonnet are pressed together by the double-head stud bolt
3. The stability of plug movement is improved due to the strong cage guide and the unique balanced sealing ring (GF TFE structure for room temperature, graphite 1398 & Graph-lock structure for high temperature) so that the vibration and mechanical noise are reduced
4. With the solid cage, the valve body is protected from steam and cavitation damage. There was an S streamlined channel and this makes the small loss of pressure drop, high flow, and wide range of control.
Benefits:
1. Compared with an un-balanced single seated straight-through valve, the equipped actuator can be smaller for the balanced structure plug, however, it can overcome higher pressure differences and with a better price
2. The flow characteristics can be changed by different cage window shapes, and thus promote the part's commonality.
3. Noise can be reduced by 10dB compared with the ordinary single/double seated control valve
4. Easy and fast replacement for valve parts even when the valve body is in the pipeline, this makes maintenance easier. The valve parts of the standard cage can be easily replaced by the multi-hole cage in order to apply for different conditions, and this can ensure the outflow is within the security range to prevent cavitation and reduce the noise.
