  • Water hammer
  • Dry running of pumps
Leader Air Release Valve typically designed to mount at the high Points in a piping system to automatically remove pockets of air as they accumulate, The valve can also be used to slowly release air in tanks and pump casings.

 

  • Float-operated, resilient-seated valve designed to handle clean fluids.
  • Single Ball Type, EPOM Coated Wooden Balls
  • Used to release entrapped air in any piping system.
  • Maintains system flow efficiency.
  • Temper Proof design eliminates wastage of water
  • Screwed Male Threads to BS:21
  • An isolating valve must be provided below the air release valve ta isolate it while doing the maintenance in the air release valve
  • Widely accepted by Municipal Corporations, Irrigation Authorities, Water Supply Authorities, National Thermal Power Corporations, Nuclear Power Corporations, and Industrial users.
