The ABS Metric SX Easyfit Check Valve - EPDM is a high-performance true union non-return valve designed to allow flow in one direction while reliably preventing backflow in ABS metric pipework systems. Manufactured by Georg Fischer as part of the advanced SX Easyfit® range, this valve combines durable ABS construction with an innovative installation and maintenance concept.

The valve uses a stainless steel spring and EPDM sealing mechanism to provide fast, reliable closure when flow stops or reverses. This makes it ideal for protecting pumps, equipment and pipework from backflow damage in pressurised systems.

Developed in collaboration with Giugiaro Design, the SX Easyfit check valve features the patented Easyfit system, which controls the rotation of the union nuts during installation. This ensures consistent tightening, improved joint integrity and reduced installation errors, particularly in confined spaces.

Its fully unionised design allows the valve body to be removed easily from the pipeline without cutting the pipe, enabling quick inspection or seal replacement while keeping disruption to a minimum.

• One-way flow control: Prevents backflow and protects system components
• SX Easyfit® design: Advanced true union check valve for industrial use
• Stainless steel spring mechanism: Reliable closing response
• EPDM seal: Suitable for water and many industrial fluids
• High pressure rating: Up to 16 bar at 20°C
• Patented Easyfit system: Controlled union nut rotation for secure installation
• Fully unionised body: Valve can be removed without disturbing pipework
• Compact design: EN 1452 short-series dimensions for space-saving installs
• Maintenance in situ: Seals and seats can be replaced without removing the valve body
