Detail Infomation
Top Entry Trunnion Ball Valve
The special "V" seating design introduced the self-adjusting seat to the isolation ball valve. This design does not rely on the built-in interference of conventional floating ball valves. It provides automatic compensation for pressure, temperature and wear. As these changes occur, the ball and seats are continuously snugged down into the "V" resulting in positive leak-tight shutoff when using resilient seats. Maintaining a low-pressure seal has been the most difficult condition for floating ball valves. The wedge effect on the ball and seats down the "V" assure continued low pressure sealing for the life of the seat. All Apollo Top Entry Valves have an "anti-static" feature designed. All valve configurations also feature blow-out proof stems as standard.
Features:
· One-piece flange top-entry trunnion design
· Double block and bleed
· One-piece ball and stem assures precise positioning
· Anti blowout one-piece ball/stem design
· O-rings plus fire-safe packing prevents leakage
· Corrosion resistant low friction bearings
· Wave springs provide upstream and downstream sealing
· Stainless steel sealant injection fittings for the emergency stem of seat sealing
· Inline repairable due to reasonable seat retainer design
· Minimized torque required to open and close valve
· Anti-static grounding between ball, stem and body
· Integral top works direct mounting pad
Size Ranges: 1/2 - 20 Inch
Pressure Ratings: ANSI Class 150 - 2500 LB
Standards Compliance: API 6D, BS 5351, ASME B16.34, DIN 3202 or Equivalents
