The Tower 22 mm Automatic Boiler Bypass Valve is a genuine, high‑performance solution for heating systems that need a reliable boiler bypass—especially those fitted with thermostatic radiator valves (TRVs) or zone valves. Once set, the valve automatically balances system pressure, keeping noise down, protecting pump impellers and extending the life of the boiler’s heat‑exchanger by guaranteeing a steady minimum flow.
Key benefits
– Steady flow – up to 50 L /min (≈ 3 m³ /h) ensures the boiler never starves for water.
– Wide pressure range – works from 0.1 to 0.6 bar differential and tolerates up to 6 bar working pressure.
– Noise reduction – smooth pressure regulation eliminates the “click‑clack” of closing TRVs or zone valves.
– Easy adjustment – a lockable set‑pressure knob lets you fine‑tune the valve and secure it with a simple top screw.
Technical specs
– 22 mm compression fittings
– Max temperature 110 °C
– Flow capacity 3 m³/h (50 L/min)
– Differential pressure: 0.1–0.6 bar
Installation tip
Place the valve in a loop between the pump’s flow and return pipes, following the arrow on the body. Rotate the adjustment head until the desired setting appears, then lock it in place. Refer to your boiler manual for the exact set‑point based on system size and TRV configuration.
Ideal for modern hydronic heating, this bypass valve delivers consistent performance while protecting your equipment and keeping your home comfortable.
