ELECTRICAL OPERATED PISTON VALVE - 9750 SERIES

The Piston valve is seat less and glandless valve. At the heart of the piston valve are piston and sealing rings. A burnished piston seals against metal reinforced graphite rings to achieve leak proof shutoff. The piston valve which has achieved world-wide recognition mainly due to tight sealing against high temperature and pressure.

  • The unique design ensures long life even at temperature up to 800°F (427°C).
  • Piston Valves contrary to globes valves are bi directional.
  • No metallic sealing surface are present.
  • The sealing system is astonishingly simple and extraordinarily effective; always leak-tight across the ports and to atmosphere.
  • Maintenance free
  • Compensation for thermal expansions
  • Unaffected by foreign matter in the
  • Temperature compensation considered as standard during sizing and selection of bellows.

  • Larger effective sealing area – 88% more than globe valve: zero leakage assured.
  • Durability – piston remains unexposed to media
  • Absence of gland and valve key
  • The only scrap free valve
  • Fire proof
  • Maintenance friendly
  • Self-cleaning
  • Self-Lubricating
