DNS ARVS Single Air Release Valve
Spec Sheet: DNS-ARVS Single Air Release Valve
Certification: Available on request
The DNS-ARVS Single Air Release Valve is installed at the peaks of a pipeline to continuously exhaust the small pockets of dissolved air (around 2%) that come out of solution as water flows. Releasing these bubbles prevents air locks and maintains efficient flow through the pipeline.
