Technical characteristics
  • MaterialBronze
Description
  • Reliable, precision machined and low torque design in general requiring no maintenance through out service life.

  • Designed to meet IS 3224:2002 and EN ISO 10297:2006.

  • Design provides O-ring backed by high durometer elastomer back up ring for external tightness. Thrust washer between the top spindle collar and gland nut further protects the O-ring at high pressure. Combination of simultaneous metallic and non metallic sealing designed to resist acetylene flashback.

  • Gland nut abutts at the inner end with the valve body ensuring metal to metal seal eliminating need to retighten the gland nut.

  • Spindles machined from naval brass for toughness and wear resistance except top spindle for key operated valves which is machined from SS-304 rods and designed to fail safely, below square at a closing/opening torque between 65-70 Nm. This ensures that in case excessive torque is applied on the operating mechanism; the spindle shears before damaging the bottom spindle and the valve body.

  • Bottom spindle threads, thrust washer, 'O' ring and back up ring are lubricated to eliminate seizing and galling.

  • Valve body withstands impact strength of 400 J making it suitable for cylinder package mass of 111 kgs, if used without valve guard.

  • Valves provided with Stainless steel filter at inlet.
