Check Valve
- C17 Slanted Seat Tilting Check Valve
- DENZ-C17 Slanted Seat Check Valves are installed in pumping applications to prevent backflow in the network. Each interior part is suitable for use in drinking water systems. Due to its slanted seat, the valve closes before reverse flow occurs, which mitigates pressure surges. The valve can also be fitted with a hydraulic damping device to further reduce the risk of water hammer. The valve is designed for both soft sealing and metal seated types.

DENZ-C17 Slanted Seat Check Valves are installed in pumping applications to prevent backflow in the network. Each interior part is suitable for use in drinking water systems. Due to its slanted seat, the valve closes before reverse flow occurs, which mitigates pressure surges. The valve can also be fitted with a hydraulic damping device to further reduce the risk of water hammer. The valve is designed for both soft sealing and metal seated types.
• A fast reversal of flow direction in conventional swing check valves is often followed by loud slams and mechanical pressure surges stressing pipelines and foundations. In the event of the back flow suddenly stopping, pressure surges can lead to the destruction of the pipeline.
• ENGJS500-7 Ductile iron body and bonnet for high strength and impact resistance.
• Travel of disk reduced by 25% due to slanted position of the seat, closing time also reduced.
• Disk closes without slamming due to damping unit activated at 10 to 15% before final closing
• position of the disk (optional).
• Compact design.
• The seal is easily replaced when the valve disc is open
• Sealing ring completely relieved from stress and wear
in the open position
• Shear strain of the rubber seat much reduced due to
the high eccentricity
• Optimum closing of rubber seat into the body seat
• Metal sealing, corrosion and wear resistant sealing surfaces.
• Face-to-face dimension according to EN 558-1, basic series 14. (production range F4, DIN 3202)
• 100% of the valves are subjected to Hydrostatic tests according to EN 12266-1. Pressure for seat: PN x 1.1 ,
for shell: PN x 1.5
