• Permitting ease of operation, minimizing the torque and reducing seat seal wear.

  

• Double O-rings, or the combination of O-rings and gaskets, enable a perfect and safe sealing of all body
  joints.

  

• Antiblowout stem allows the replacement of the stem seals with the valve in the fully closed position. The
  stem seal integrity is achieved by the use of three O-rings. The upper seal can be replaced with the valve in
  line and under pressure. Stem and ball are separate components; this ensures a better alignment and lower
  torque. Stem and trunnion are supported by P.T.F.E. impregnated steel bearing sleeves. Emergency stem
  sealant injection feature is standard on valves 4” and above.

  

• Independent floating spring loaded seats are always in contact with the ball to provide an effective tight
  seal even at low differential pressures. Independent upstream and downstream seats permit draining of
  fluid from the body cavity, allowing double block and bleed operation. With the standard single piston seats feature, there is an automatic body cavity release of over pressure to the line through the down stream seat.

  Double piston seat (that maintains the sealing capacity of the valve even in the case of failure of the up
  stream seats) or a combination of double sealing features on the downstream side/single sealing on the
  upstream seat is available on request. A seat emergency sealant injection system is available on request
  which can restore the sealing integrity if damage occurs to the sealing surfaces.
