- Single-leaf wastewater check valve, ensuring pump protection against flow reversal.
- Low pressure loss.
- Full passage ensured by the total clearance of the leaf, no risk of clogging.
- Tilted position valve, reduction of closing noise thanks to a shorter stroke.
- Wide seat support limits wear phenomena, even with high pressures.
- Fully covered leaf of elastomer.
- Tightness even at low pressure.
- Easy maintenance: removable cap: allows the leaf to be changed without removing the valve from the pipe.
- Simple design: leaf housed in cast iron, no risk of clogging.
- Anti-corrosion protection by 250 micron interior/exterior epoxy coating.
- Horizontal or vertical upward mounting
- Complies with the NF EN standard 12050-4.
