ACO QUATRIX® Backflow valve with access chamber The ACO QUATRIX® backflow valve is an in-line Type 3 automated anti-flooding device conforming to BS EN 13564 suitable for black water connections (faecal wastewater) installed with its own access chamber. The motorised flap activates and shuts under pressure sounding an audible alarm accompanied by a flashing light. When backflow abates the process is reversed. In the event of a power cut, the control box has a 24 hour power back-up. Versatile design Quatrix backflow devices have a 2-position secondary flap for manual operation. The ACO QUATRIX®, which installs into solid floor construction with connection to 110mm and 160mm Ø drain pipe, features a height adjustable access chamber with optional DPM bonding flange. Access is gained through a reversible cover designed for tiled or cementitious floor finishes which rotates for ease of alignment with floor tiling and is fully sealed. The IP67 rated motor/valve body ideal for internal or external applications. 1.
