1 Inch Air Release Valve


Product Description

The automatic air release valve adopts a simple “ball float” operation using a renewable hard rubber ball located at the upper valve chamber. Air in the pipework is released through the vent hole when it is initially charged up with water until water reaches the ball chamber. The rubber ball will be pushed upwards to the vent hole and sealed it when the network of pipe is pressurized.
No maintenance is required but if any small debris is trapped at the upper valve chamber, this can be removed by opening the cap at the top.
