It is designed for installation in systems where a boiler bypass is required, typically when a system is equipped with thermostatic radiator valves (TRV's), and to allow pump overrun operation after zone valves have closed down. When correctly set, this valve will regulate system pressure, thereby reducing system noise, pump impeller wear, and enhance boiler heat exchanger life by ensuring a minimum flow rate at all times. Specifications: High capacity flow up to 50 litres per minute. Wide differential pressure range 0.1 bar.

FAQs
What is the purpose of an auto bypass valve?
An auto bypass valve prevents issues like boiler cycling and pump damage by allowing water to circulate when TRVs close.
Where should the auto bypass valve be installed?
It should be installed in the bypass loop, between the flow and return pipes of the heating system, usually after the pump.
How do I adjust the valve?
Refer to the manufacturer's instructions for the specific valve. Adjustments typically involve setting the pressure relief point.
What happens if the valve is not set correctly?
Incorrect settings can lead to system noise, poor heating performance, or premature boiler shutdowns.
Is this valve suitable for all heating systems?
No, it's primarily designed for systems equipped with TRVs or those requiring a boiler bypass.
What is the maximum flow rate this valve can handle?
The valve can handle a high capacity flow up to 50 litres per minute.
How often should I inspect the valve?
Regularly inspect the valve for leaks and ensure the system is flushed after installation.
Troubleshooting
System noise persists after installation.
Check the valve setting and adjust as needed. Ensure all TRVs are functioning correctly and that there are no airlocks in the system.
Boiler shuts down frequently.
Verify that the bypass valve is opening when TRVs close. Check for blockages or restrictions in the bypass loop.
Poor heating performance.
Check the valve setting, ensuring adequate flow. Inspect the system for blockages or airlocks that might be restricting flow.
Pros and Cons
Pros
Reduces system noise caused by pressure fluctuations.
Extends the lifespan of the boiler heat exchanger.
Minimizes wear on pump impellers.
Provides a consistent minimum flow rate, even when TRVs are closed.
Cons
Requires proper installation for optimal performance.
Setting the valve correctly might require some adjustment.
Not suitable for all types of heating systems.
May require additional components for installation.
Setup, Compatibility & Care
Setup:
Installation: The valve should be installed in the bypass loop, typically between the flow and return pipes of the heating system, after the pump.
Direction: Ensure the valve is installed in the correct flow direction, following the arrow on the valve body.
Settings: Adjust the valve according to the manufacturer's instructions to achieve the desired pressure.
Compatibility:
Compatible with systems using TRVs.
Suitable for systems with a boiler bypass requirement.
Verify pipe size (22mm) and connection type before installation.
Care:
Regularly inspect the valve for leaks.
Ensure the system is flushed after installation to remove debris.
Check and clean the valve periodically, especially if the system contains debris.
