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, valve body and the upper bonnet are pressed together by the double-head stud bolt
3、The stability of plug movement are 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, valve body are protected from steam and cavitation damage. There was a S streamlined channel and this makes small loss of pressure drop, high flow, wide range of control.
