Specifications:

  • Sizes: 80mm / 100mm / 150 mm / 200 mm
  • ANSI Class 150 standard
  • Flange drilling as per  ANSI B 16.5 standard

Valve Components and Material of Construction:

  • Valve Body, Cover CS ASTM A216 Gr WCB
  • Seat Ring – AISI 304 (S.S. 304)
  • Disc Retainer – AISI 304 (S.S. 304)
  • Stem – AISI 304 (S.S. 304)
  • Stem Nut – AISI 304 (S.S. 304)
  • Guide Bushings – AISI 304 (S.S. 304)
  • Diaphragm – Neoprene with nylon reinforcement
  • Fasteners – High tensile steel
  • Pilot Tubing : Stainless steel

Advantages:

  • Huge cost saving in power consumption of valve operation (Compared with Electrical or Pneumatic Actuated Valves). Valve can be operated using solar panels
  • Requires minimal maintenance  (only one moving part)
  • Adjustable closing speeds, avoiding destructive water hammers
  • Offers significant water loss savings (Due to tank overflow, pipe bursting, timed operations etc.)
  • Supplies water at preferred pressures
  • Precisely controls reservoir water levels
