Air & Vacuum Release Valves

Air & Vacuum Release Valves

Protect your pressurized pipelines from damage caused by air-related pressure surges, and keep your system running efficiently by installing these valves. Air release valves continuously release accumulated air during system operation. Air vacuum valves exhaust air at system startup to prevent vacuum damage or pipeline collapse if negative pressure develops during operation. Valves meet AWWA (American Water Works Association) C512 standard and have a resilient float seat that provides positive shutoff down to the lowest system pressure.

Clean Water Air Release

An excellent choice for clean water distribution and transmission systems, these valves are designed to reduce the build-up of debris and scale.

Wastewater Combination Air Release & Air Vacuum

These valves resist corrosion caused by the harsh chemicals found in wastewater, and the non-clog design reduces the need for maintenance.

Clean Water Air Vacuum

Commonly used with vertical pumps in wells or water reservoirs, these valves are designed to prevent the flow of contaminated water into your system during power failures, line breaks, and maintenance shutdowns. Also known as well service valves, these low-lead valves are certified for use in potable (drinking) water applications.

Combination Air Release & Air Vacuum

The most commonly used air valves in water systems, these combine two valves in a single body for the most compact size. They continuously release air during operation while also expelling air buildup when the system starts up, providing a high level of protection for your pipeline.
