Principle Features

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

Reduction of flow
Pressure fluctuations
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.
