Double Orifices Automatic Air Vent Valve

Model NO.: GAP

Applications:

Double Orifice automatic air vent valve is used in the industrial pipelines to release the air in the pipeline quickly, so as to improve the transmitting efficiency and prevent pipelines being broken and out of shape.

Characteristics:

1. Release the air in the pipelines, reduce the resistant force and save energy.

2. Suck the air automatically and quickly so as to prevent the pipelines being broken while the backpressure is higher.

3. The air vent ability is better than the normal air vent valves

4. Stainless steel floating ball and supporting ring can make it reliable and can be used longer.
