Automatic Bypass Valve
Benefits This quality automatic bypass valve controls water flow in the central heating circuit according to the water pressure across it, maintaining a minimum flow rate through the boiler and limits circulation pressure when TRV’s or other water paths are closed. This prevents your system from “cycling”.
Features • High capacity flow up to 50 litres per minute • Adjustable differential pressure range 0.1 to 0.6 bar • 22mm compression fittings for ease of installation
• Ensures constant flow through boiler • Reduce system noise and maintain an even system pressure
Applications TRV’s slowly close down after each radiator raises the room temperature. To overcome flow restrictions as TRV’s close down, the ABV is adjusted to the required set point. As the system resistance increases due to TRV’s closing, the ABV allows flow to increase, in order to maintain the required pre-set system differential pressure. The regulation provided will reduce system noise that can result from TRV’s or zone value is closing, eliminate pump impeller wear that can result from high flow resistance, and enhance the life of the boilers heat exchanger by ensuring minimum flow rate at all times.
