BLOW-OUT PROOF STEM DESIGN
The stem is designed separated from ball, and designed as T slot shape at the bottom side, and gland flange will prevent the stem blow out in case of any abnormal cavity pressure increase.
ANTI-STATIC DEVICE
The electrical conductance continuity connect the ball, stem and body, it can avoid the any fire or explosion caused by the static that might be produced and accumulated by friction between the ball and seat ring during valve open or close.
FIRE SAFE DESIGN
External leakage prevention
In normal condition, leakage through the valve stem area is prevented by two O-ring seals and a gland packing. Leakage through the valve body and bonnet connection is also blocked by an O-ring seal and a body gasket. In the event of a fire, O-rings will be melted or decomposed under higher temperature in the fire, then the fire safe body gasket, stem packing will prevent external leakage.
Internal leakage prevention
Internal leakage prevention
In the event of a fire, all none metal materials, like O-rings, soft seats and back rings, will be melted or decomposed under high temperature in
the fire, the edge of metal seat energized by the seat spring will contact with the ball to block the pipeline medium and minimize internal leakage.
Also the fire safe graphite packing is compressed into the seat ring groove to prevent process media leakage through the gap between the valve
body and seat.
