GS feeding ball valve series, one-piece body structure increasing inlet flange design, reduce the valve ball net space, prevent effusion, axis of the stem design a certain Angle, the stretched connection structure, to prevent interference with the bottom of the kettle. Meet the demand of operating space, blow out proof stem, spring loaded valve seat seal structure (hard seal). Non-metallic seat 230 degrees heat resistance.
Product Description
Discharge valves are mainly used for discharging material from the bottom of storage tanks, reactors and other vessels. The valve is connected to the equipment and is located at the bottom by flanging or butt-welding to eliminate the residual phenomenon of process media usually at the outlet of the vessel. According to the needs of the actual situation, it is divided into upward display type and downward display type. The upward type is used for kettle discharge with a stirring discharge valve; the downward type is used for kettle discharge from frame-anchored stirrers.
Integrated body structure
Increased inlet flange, no dead corner , no liquid hydrops.
Stem incline with a angle to prevent interference with reactor bottom, elongated connection structure, ensure operational space
Anti blow-out stem
Spring loaded seat seal construction (metal seal)
Non-metallic seat , temperature resistance of 230℃.
