GOLIA 3F EO

Combination air valve - Version for air discharge only

The CSA EO system, designed to avoid under any circumstances the air entrance back to the pipeline, only allows the exhaust of large volumes of air during pipe filling and the discharge of air pockets in working conditions. The unit regulation device EO, 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 EO model, in case of pipe draining, burst and pump failure the system won’t be protected against negative pressure conditions.
