API Globe Valve

Product Usage
J41H, J41Y, J41W API American Standard cut-off valve opening and closing pieces are cylindrical disc, the sealing surface was flat or tapered surface, the valve flap 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
