Product description

Our combination air valve for sewage guarantees the proper operation of sewage lines, the valve serves three functions including: allowing the entrance of a large quantity of air in case of pipe burst or draining, the release of air pockets during working conditions and the discharge or air during pipe filling.

1) Discharge of large volumes of air

During the pipe filling it is necessary to discharge air as water flows in, the aerodynamic full port body and deflector avoids premature closures of the mobile block during this phase.

2) Air release during working conditions

During operation the air produced by the pipeline is accumulated in the upper part. Little by little it is compressed and its volume increases, pushing the liquid level downwards allowing the air release through the nozzle.

3) Entrance of large volumes of air

During pipeline draining, or pipe bursts, it is necessary to bring in as much air as the quantity of outflowing water. This is to avoid negative pressure and serious damages of the pipeline and the entire system.

Key features

Lower body designed with strongly sloped high walls to avoid deposit of grease and/or other material

Upper body containing the air release device is protected against projections during rapid filling by a stainless steel deflector

Mobile block, including a large AISI 316 stainless steel float, connected through a stainless steel rod to the air release mechanism

Compact and light, suitable for the most demanding environments

Drainage valve for chamber control and draining

Maintenance can be easily performed from the top without removing the air valve from the pipe

Evacuation bend suitable for flooded environments with 1 inch threaded outlet
