Air Release Valves
Val-Matic Air Release Valves mounted at high points within the piping system will remove all pockets of air as they accumulate. They provide an inexpensive method of preventing the difficulties that occur when air is entrained in a water line. In addition, the superior design, workmanship, and stainless steel trim provides a quality valve, one which will give many years of maintenance free and trouble free operation.

Air / Vacuum Valves
Air / Vacuum Valves perform two important functions when mounted at high points on pipelines.

First of all, they allow large quantities of air within the line to be exhausted as that line is being filled. When the air has been vented and the fluid level reaches the air / vacuum valve, the float rises and seals tightly against a synthetic seat.

Secondly, in the event of the line being drained, either intentionally or through a fracture in the system, the air / vacuum valve responds to the loss of pressure and opens. This allows air to re-enter the pipeline and prevents a potentially damaging vacuum from developing.

Combination Air Valves
The Val-Matic Combination Air Valve performs both the functions of Air Release and Air/Vacuum Valves. The Air Release valve portion vents air which accumulates at high points in a system during its operation. The Air/Vacuum valve portion will exhaust the larger quantities of air present in a system during the filling and allow air to re-enter during draining. They are available in both single body and dual body configuration.
