Features
- The SDCV features a slanted disc that closes at a low angle to the flow direction, significantly reducing the closing velocity and disc slam compared to conventional swing check valves
- The low headloss design minimises pumping energy
- The slanted geometry ensures self-closing under gravity with minimal reverse flow
- Suitable for pump discharge on clean water and treated effluent
Description
The SDCV features a slanted disc that closes at a low angle to the flow direction, significantly reducing the closing velocity and disc slam compared to conventional swing check valves. The low headloss design minimises pumping energy. The slanted geometry ensures self-closing under gravity with minimal reverse flow. Suitable for pump discharge on clean water and treated effluent.
Selection notes
This check valve is supplied for flanged installation.
Sizes run DN200 to DN1600, in PN10, PN16.
The body is EN-GJS-400-15 (GGG-40).
Seat and trim options are Nickel alloy welded. The seat, not the body, usually sets the temperature and medium limit, so confirm it against the service before ordering.
It is catalogued for Water & Wastewater and Industrial Process.
Working temperature is -10°C to 80°C.
Built to EN 12334 and GSK (epoxy powder coating).
