WW-C70-AC-S Combination Air Release Valve c/w Assisted Closure

Description

BERMAD C70-AC-S is a high quality combination air valve for a variety of water networks and operating conditions specifically designed to reduce the effects of water hammer when there are rapid changes in pipeline velocity.

Under column separation hydraulic conditions, the air valve allows air to re-enter the pipeline unrestricted, and then discharges air at a very slow controlled rate in order to minimize any potential water hammer.  In order to maximize pipeline efficiency the valve also automatically releases any entrained air when under water pressure to maximize the flow capability of the pipeline.

With its advanced aerodynamic design, double orifice and anti-slam / slow closing device, this valve provides excellent protection again air accumulation, vacuum formation and pressure surges, with improved sealing in low pressure conditions. The valve minimizes water spraying during air release.
