Product Description

Vacuum Breaker Air Release Valve

The triple function air valve is installed at the pump outlet or in the water supply line to remove a large amount of air from the pipe or discharge a small amount of air collected at a higher level of the pipeline into the atmosphere, so as to improve the efficiency of the pipeline and the pump. Once in case of negative pressure inside the pipe, the valve will quickly absorb the outside air to protect the pipeline from damage caused by negative pressure.

Why Choose US

We control the material of PTFEand stainless steel wires per customer's request.

Some are from Japan and Taiwan, some are from China local. Only choose high quality material.

We test leakage of each roll before braiding, then we cut 300mm and crimp it to test

burst pressure after brading.

We use CNC Lathes Machine for end fittings production. Machine system, knife and inspection

tools are all imported from Japan.

We use Techmaflex Crimping Machine which is imported from France. This machine has

accurate and stable performance for crimping because it is produced for PTFE hose crimping only.
