Triple effect suction pad made of ductile cast iron DN80 flange.
Triple effect suction valve to expel the air contained in the water when the installation is loaded. It also incorporates an automatic DN-1 ”suction cup to eliminate air when the installation is under load, avoiding performance losses and equipment errors.
Functioning by floating polypropylene ball.
PN-16 working pressure.

The suction valves are the indicated device to allow the elimination of air from the pipeline thanks to their operation based on the float closure.
In the moments of filling and emptying the pipe, the water column pushes or absorbs large amounts of air that have to pass through the air valve. Filling is the most critical process, as it is necessary to evacuate a large amount of air at high speed.
The automatic air valve provide the installation with the necessary level of security with contained costs and with a minimum need for maintenance.
This type of air valve are suitable for all types of installations, also being offered in various configurations and a multitude of diameters.
