Principle Features

INTRODUCTION
The inclusion of air in water can have a very considerable negative effect on the functioning of pipeline system, such as

  • Reduction of flow
  • Pressure fluctuations
  • Water hammer
  • Dry running of pumps
Leader Air Release Valve is typically designed to mount at the high points in a piping system to automatically remove pockets of air as they accumulate, The valve canals are used to slowly release air in tanks and pump casings.

 

  • Foat-operated, a resilent-seated valve designed to handle clean fluids.
  • Double Ball Type, EPDM Coated Wooden Balls.
  • Used to release entrapped air in any piping system.
  • Maintains system flow efficiency.
  • Temper Proof design eliminates wastage of water.
  • Flanges as per BS:4504 PN1O(FF) Drilled.
  • An isolating valve must be provided below the air release valve to isolate it while doing the maintenance in the release valve.
  • Widely accepted by Municipal Corporations, Irrigation Authorities, Water Supply Authorities, National Thermal Power Corporations, Nuclear Power Corporations, and Industrial users.

END CONNECTION

  • Flanges as pr BS:4504 PN10 (FF) Drilled.
  • Flange drilling as per other standards also available upon request.
