  • Positive alignment of body.
  • Blow-out proof stem for safety.
  • Sphericity tolerance of the ball is unsurpassed.
  • Multiple layers of adjustable PTFE chevron packing rings for standard model enable excellent fugitive emission control.
  • Positive position indication.
  • Locking device capable.
  • Heavy duty body construction.
  • Machined ISO 5211 top mounting flange.
  • Live load springs keep constant force on stem-seal packing, ensuring seal integrity and extended valve life.
  • Dual shaft bearings for high cycle life operation.
  • Higher Cv values and less cost for diverting which can be normally done with multiple installation of valves.2 seats feature OM2 compatible, co-polymer E-seat as standard. Machined firesafe lip for metal touch to ball in case of fire. It also eliminates
