Vacuum in a water transmission main, due to closing of a valve, pump stopping, draining… can cause serious damages like :
- Ovalisation or flatening of the pipe
- Moving or suction of gaskets
In order to avoid this phenomenon and its consequences, the “Inlet R-Safe valve“ allows a quick air inlet at huge flow rate into the pipe, thus reducing the depression.
Applications :
- • Drinking water networks
- • Raw water networks
- • Irrigation networks
Product benefits :
- Body and valve allowing air flow rates with low pressure drop.
- Watertight by its own weight (0.2 bar).
- Cone boosting the Venturi effect.
- Reliable and simple to use system. No maintenance.
Range :
- DN 80 to 400.
- PFA 10
Technical data :
- ISO PN drilled flanges according to PFA (EN 1092-2 et ISO 7005-2 standards)
- Working temperature : +0°C to +70°C.
Alternatives and options :
- PFA 16, 25, 40
- Special manufacture on request (stanless steel, super duplex).
