Compared with other plant air valves, ours have not only large air exhausting and large air intake under invacuum,but also one more function of small air releasing.

Single valve chamber,unlike many connected bodies are easy to break up during transportation. All internal accessories are of AISI 304SS, hardness and quality are quaranteed.

There is a seal gasket in the valve above big float and it helps orifice make better sealing effect. With rubber seal gasket above float, it can absorb water hammar to avoid crash with seal arc and valve body and protect air valve from hurting.
