SGC Bushing and Port Guiding Perforated Plug Type
SGC also is the basic type among SH6000 high performance control valves.
Metal-seated quick-changeable trim combination. Particular effective for liquids and
compressible fluids at high pressure drop ratios. Perforated cylinder Plug can
effectively protect sealing surface of seat to be damaged by high speed flow scoured.
The flow which directly pass through the holes of the trim is divided into numerous
jets of cavitation liquid. In the centre of the cage the jets impact and the vapour
bubbles collapse. Here, they don't cause any damage to the valve internals and the
noise level is also reduced by 5-10dBA.
SGC series is suitable to verous heavy duty services.
