Aco Quatrix Backflow Valve

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) complete with its own access chamber.

Versatile design

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.

Reliable function

Under normal conditions the backflow flaps are open allowing waste water to flow to the drain. When backflow occurs, reversing the direction of flow, water will reach a certain level within the pipe activating a pressure sensor which is monitored at the control box. The motorised flap activates and shuts under pressure sounding an audible alarm accompanied by a flashing light. Once
backflow abates the process is reversed. In the event of a power cut, the control box has a 24 hour power back-up. Quatrix backflow devices have a 2-position secondary flap for manual operation.
