By-Pass Valve 22mm

The Honeywell 22mm Bypass Valve is designed to maintain consistent differential pressure within heating systems. This valve helps reduce flow noise, especially when thermostatic radiator valves are closing, and raises the boiler return temperature, minimising corrosion caused by flue gas condensation. Additionally, it maintains flow over the boiler's temperature sensor when radiator valves are closed, ensuring the proper functioning of external temperature compensating controls.

Honeywell 22mm Bypass Valve: Key Features and Benefits:

• High Capacity Flow: The DU145 valve can handle flow rates of up to 50 litres per minute, making it suitable for a variety of heating systems.
• Wide Differential Pressure Range: With a range from 0.1 to 0.6 Bar, this valve accommodates diverse system requirements.
• Simple Adjustment Mechanism: The unique adjustment mechanism allows for easy and precise control.
• Easy Installation: Featuring 22mm x 22mm compression fittings, the DU145 is straightforward to install.
• Noise Reduction: By maintaining even system pressure, the valve reduces noise throughout the heating system.
• Consistent Boiler Flow: Ensures a constant flow through the boiler, supporting optimal performance.
• Lockable Set Pressure: Prevents inadvertent adjustments, ensuring stable operation.

Why Choose the Honeywell 22mm Bypass Valve?

• Optimise Heating System Performance: Maintain consistent differential pressure and reduce noise in your heating system.
• Prevent Corrosion: Raise boiler return temperature to minimise flue gas condensation-related corrosion.
• Support Proper Sensor Operation: Ensure constant flow over the boiler’s temperature sensor for accurate temperature compensation.
• Guaranteed Minimum Flow: Ensure minimum flow circulation in gas-fired water heaters, even when thermostats or radiator valves are closed.
