YobiLife Brass Bypass Valve – 33MM Thread

The YobiLife differential pressure bypass valve is a precision-engineered component designed to optimise hydraulic balance in underfloor heating, heat pump, and HVAC systems. Its compact 33mm thread diameter and 155mm height make it ideal for installations where space is limited, ensuring it can be integrated into tight plumbing layouts without compromising performance. The valve’s self-regulating mechanism automatically adjusts to pressure fluctuations, reducing hydraulic interference and protecting sensitive components—such as circulation pumps and control valves—from excessive wear. This enhances system longevity while maintaining consistent water flow and energy efficiency.

Featuring a dual-unit pressure gauge with 360° visibility, the valve provides clear, accurate readings in both bar and mH₂O, simplifying pressure monitoring from any angle. This dual-scale display is particularly useful during commissioning, maintenance, or troubleshooting, allowing technicians to fine-tune system performance with precision. Constructed from solid brass, the valve offers durability in wet heating environments, making it suitable for residential and light commercial applications. Its versatility extends across underfloor heating, heat pump systems, centralised heating, and air conditioning setups, positioning it as a reliable solution for balancing pressure in diverse HVAC configurations.

As an essential component for small boiler heating systems, this bypass valve ensures stable operation by mitigating pressure spikes and improving flow stability. The included package contains one unit, ready for immediate installation. Whether used in new builds or retrofitted systems, its space-saving design and robust construction make it a practical choice for maintaining optimal hydraulic performance in heating networks.
