 AIR CUSHION VALVE

Operates to break the vacuum where seperation takes place and reduce the inertia of returning water column by using air taken i as cushion

Construction and working principle of AIR CUSION VALVE

Construction Features

  • Available in 100, 150, 200 and 300 mm NB
  • Rugged and sturdy fabrication of the air cushion valve
  • Flange mounted on toe of the pipe
  • Very light weight ball for effective control of water outlet
  • Stainless Steel grade 304 spring is used for longer  life of the spring
  • MS epoxy painted body for surface finish is provided for air cushion valve

When The Pump Trips

  • As the seperation occurs, air is taken in through air inlet port at low differential head.
  • The air can be taken in even in presence of water at low pressure to prevent development of negative pressure

When water column returns

  • Air escapes port allows exit of air supply when pre-determined pressure is reached.
  • The compressed air offers a 'CUSHION' to the returning ware column.
  • Controlled release of air ensures that the velocity of the returning column is reduced.
  • Once all the air has escaped, the ball closes the passage and prevents water from leakage.

Salient Features

  • Self actuation
  • Does not require any external energy for actuation. Can be installed at remote locations.
  • Versatile. Can be used for almost all kinds of mains.
  • Flange mounted on the pipe
