  • Alexander Valve & Supply’s Model A3 Ball Valves are produced as either a two-piece or three-piece design threaded together to facilitate field repairs and maintenance.
  • The ball is the shut-off element because it is aligned to the bore by the seats.
  • Ball travel is controlled by a stop pin or cap-screw and valve stop or handle.
  • Blow-out proof stem is positively retained by the body.
  • The thrust wash between the steam and body ensures lower turning torque while providing a secondary seal.
  • Packing is also adjustable, utilizing a spring washer and/or handle nuts.
  • O-rings between seats and body provide sealing at low pressures.
  • O-rings are placed ahead of body-cap threads providing a tight seal and protection of threads from flow media ensuring ease of maintenance.
