The Vaillant 3 Bar Pressure Relief Valve is an essential safety component designed for Ecofit Pure VU and Ecofit Sustain VU boiler systems. This durable valve is strategically positioned inside the boiler casing at the bottom, where it plays a crucial role in maintaining optimal pressure levels.

When pressure exceeds safe limits, the valve automatically opens, providing a release pathway for the pressurized fluid and thus preventing potential damage to the system. Once the pressure returns to a safe level, the valve securely closes, ensuring the ongoing safety and efficiency of your heating system. Enhance your boiler's reliability with this high-quality pressure relief valve, engineered for consistent performance.
