Top Entry Trunnion Mounted Ball Valve

Pindee top entry ball valves are designed, manufactured and tested in accordance with API 6D and ASME B16.34.Can meet API 607 sixth edition and API 6FA third edition specification requirements. The valve size range is from 2 inch to 36 inch, pressure rating is from 150LB to 2500LB. Top entry ball valves are capable for on line maintenance, there may replace or repair the ball, seat or soft seals after strip the cover, so Pindee top entry ball valves have been widely used for oil & gas pipeline.

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 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.
