Caractéristiques

  • Conception modulaire
  • Actuator internals are protected for corrosion with CEREMIGARD a ceramic-like finish of Di-Aluminium Tri-oxide (Al2O3).
  • A powder-coated surface treatment as standard on end caps and housing provides extra protection against aggressive environments.
  • All moving parts are protected by permanently lubricated and long-lasting DURASTRIP bearings to reduce friction and increases cycle life.
  • Plated with cobalt zinc, the steel pinion is protected from corrosion and features a unique stop design.
  • NAMUR mounting (VDE/VDI 3845) allows standardization of mounting hardware for a wide range of accessories.
  • Hytork XL actuator pinion drives are manufactured to ISO 5211 with a star drive to provide extra flexibility and simplicity for direct mounting to a valve.
  • Large internal air passages maximizes valve operating speeds and adds reliability by reducing potential blockage.
  • The visual position indicator is designed for indication at a glance and can easily be converted from across-line to in-line indication.
  • The bi-directional travel stops allow easy setting of the valve stroke which prevents premature valve failures.
  • Extra large rack and pinion tooth design promotes full tooth engagement. Assists gear tooth life by reducing stress and having precise gear tooth mesh.
  • XL Springs are designed and manufactured never to break. The nested design provides a balanced concentric force on the pistons.
