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) installed into site-built access chambers or wall mounted applications. 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® plain backflow valve can connect to 110mm and 160mm Ø drain pipe. This Quatrix model with IP67 rated motor/valve body, has no fitted access chamber making it ideal for installations with deep invert pipework requiring operative access within a brick built access chamber 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. 1. Locked open (normal) 2.
