2. Design Features

  • Design Standard IS 13095 / BS EN 593 (BS 5155)
  • Wafer Type
  • Double Acting Pneumatic Actuator Operated
  • S.G Iron construction
  • Stainless Steel (CF8 / CF8M*) Disc which is accurately guided between the two stems
  • Actuator is with position indicator and adjustable center stopper for both open and closed position
  • Scotch Yoke Technology as the most suitable mechanism for valve and damper operation, producing higher torque at both end positions
  • Actuator is without Rack and Pinion for smooth operation and longer life
  • Integrally moulded rubber lining (EPDM / Nitrile / Neoprene* / Viton* / Silicon*) as per requirement which provides seating to the valve disc, as a primary seal to the stem and gasket joint with matching pipe flanges
  • Two Piece Stem design which is precisely guided between the PTFE / Bronze bushes
  • Compatible to sandwich between flanges as per BS 10 Table D, E, F,H, DIN, PN 10, PN 16, PN 25, PN 40, ASA 150, ASA 300, IS 778, IS 6392 Table 17 and IS 1538. *Valves with Neoprene / Viton / Silicon lining and CF8M (S.S 316) Disc can also be provided at nominal extra cost
