GOLIA 2F IO
Two functions air valve - Version for air entrance only
The CSA IO system, designed to avoid under any circumstances the air outflow, only allows the entrance of large volumes of air during pipe draining and burst and possibly in case of pump failure. The unit regulation device IO, whose opening differential pressure can be adjusted on request, is also available as a separate sub kit applicable to any existing CSA air valves except for the anti-water hammer AS series . User is advised that, by choosing IO model, in case of pipe filling air won’t be exhausted with the risk of problems for the entire system.
