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

Air Release Valve: Wastewater Air Release Valves are designed to release accumulated air from a piping system while the system is in operation and under pressure. The capacity and pressure rating of the valve is dependent on the diameter of the precision orifice in the cover. A large inlet connection is required for proper air and water exchange.

Flood Save Inflow Preventer: Protecting water treatment systems from terrorism and environmental contamination is the most urgent issue facing the water industry today. Inflow Prevention is designed to protect dinking water by protecting your pipelines form contaminated water becoming drawn in and mixing with potable water due to pressure changes. Inflow prevention devises are used in areas such as vaults where air valves and reservoir vents are located.

 

  FloodSafe Inflow Preventer
The FloodSafe® Inflow Preventer is a revolutionary system that works with air valves and provides unrivaled protection of potable water systems from contamination. By preventing water from passing through the FloodSafe®, contaminated floodwater or water that has been compromised by intentional tampering are prohibited from entering the air valve outlet and are subsequently unable to enter the system.

Air/Vacuum Valve: 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.

 

    • NSF/ANSI 372 Certified Lead-Free by WQA
    • Certified to NSF/ANSI 61
    • Meets AWWA C512 requirements
    • Manufactured under a certified ISO 9001 quality system
    • Available in sizes 1" - 20"
