ELECTRICAL OPERATED BELLOW SEALED VALVE - 9750 SERIES

Bellow Sealed Valves are a new breed of industrial process valves, designed to eliminate valve leakage and also known as “Zero Leak Valves” or “Emission Free Valves”.

Design:

  • Valve body in cast or forged construction to suit your requirements.
  • Spindle with bellow assembly easily replaceable-easy of maintenance.
  • Wide choice of bellow materials-including inconnel, Hastalloy, Monel, etc.
  • External Pressurization of bellow-leading to longer bellow life.
  • Welding of bellow done under most stringent conditions.
  • Bellows selected for higher stroke length than necessary-ensures longer life of bellows.
  • Temperature compensation considered as standard during sizing and selection of bellows.
