Automatic Bypass Valve Angle 22mm connects directly between the flow and return pipelines. Specifically, it provides a simple and highly reliable method of ensuring adequate flow through boilers that require a bypass. Furthermore, thanks to the easy-to-adjust manual handwheel , you significantly speed up system balancing by setting the exact required differential pressure.

Therefore, this Automatic Bypass Valve Angle 22mm works perfectly for central heating systems fitted with TRVs. Additionally, it easily handles demanding applications, such as protecting pumps when zone valves close in sealed systems or combi boiler installations.

The valve features a robust construction with a high-quality silver-coloured brass body and internal brass stem. Moreover, the material is designed for continuous operation with EPDM seals and handles intermittent working temperatures up to 120°C. As a result, this solid build makes it fully reliable for maintaining the desired minimum flow rate at all times.

Key Features & Benefits:

• Noise Reduction: The valve’s regulation allows flow to increase as system resistance rises from TRVs closing down. Consequently, you significantly reduce system noise that can result from TRVs or zone valves closing.

• Boiler & Pump Protection: The system eliminates pump impeller wear that can result from high flow resistance. Ultimately, this guarantees the valve effectively enhances the life of the boiler’s heat exchanger by ensuring a minimum flow rate.

• Quick & Easy Adjustment: The PA66 handwheel acts as a highly efficient control mechanism. Importantly, it allows you to manually adjust the pressure setting from 0.05 Bar to 0.5 Bar. Therefore, it guarantees fast setup to match your specific system requirements, with 0.2 to 0.3 Bar usually being sufficient for most domestic situations.

• Durable Brass Construction: The high-quality brass body and stem prevent structural degradation over time. In particular, this solid material also provides excellent pressure resistance, effectively handling maximum working pressures of ≤1.6mpa with total reliability.
