Sulzer - Non-Return Check Valve (ABS)

This non-return check valve is designed for use in drainage and sewage systems, ensuring one-way flow to prevent backflow. Constructed from durable cast iron or plastic, it is suitable for both horizontal and vertical discharge lines in compliance with EN 12050-4. The valve is available in ball and flap configurations: the ball check valve features a self-cleaning mechanism and provides effective sealing with minimal head loss, while the flap check valve offers silent shut-off and a full-bore design for efficient medium passage. Both types are engineered for reliable operation in wastewater and sewage applications, with no wearing parts for extended service life.
