Stainless Steel Globe Valve
roduct Usage
J41H, J41Y, J41W Stainless Steel Globe Valve is the opening and closing pieces of cylindrical valve, the sealing surface was flat or cone, the valve along the fluid center line for linear motion. GB stop valve only applies to fully open and fully closed, generally not used to regulate the flow, custom made to allow for regulation and throttling.
Features
1, the structure is simple, more convenient to manufacture and maintain
2, small work schedule, opening and closing time is short
3, good sealing, sealing surface friction, longer life expectancy
