HGC High Pressure Perforated Plug Type Control Valve
Information
HGC High Pressure Perforated Plug Type Control Valve
Large capacity high pressure globe valve body , thick wall bonnet, Metal-seated quick-changeable trim combination .HGC ensures safety and credibility in ＞100Kg/cm2 high pressure conditions. Double guided by bushing and port ,working trims are of dynamic stability. Perforated cylinder Plug can effectively protect sealing surface of seat to be damaged by high speed flow scoured.
HGC series is especially suitable for the high pressure fluid with large pressure drop and possibility of cavitition.
