Our Expert's Opinion
"A critical boiler safety component engineered to protect sealed heating systems from dangerous over‑pressure conditions."Alpha 1.028561 Safety Relief Valve
The Safety Relief Valve is one of the most important protection devices in any sealed heating system. Its role is simple but essential: when system pressure rises above safe operating limits, the valve opens automatically to discharge excess pressure, preventing damage to the boiler, pipework, and connected components. The Alpha 1.028561 3‑bar valve is engineered with precise spring calibration and robust internal mechanisms to ensure consistent, repeatable operation. Its durable brass body resists corrosion and thermal stress, while the high‑integrity sealing components maintain leak‑free performance throughout the valve’s service life. This valve is designed specifically for Alpha boilers requiring a 3‑bar pressure safety release, ensuring a perfect fit and dependable performance during both routine operation and emergency pressure events.
Features:
3‑bar calibrated release pressure - Opens automatically when system pressure exceeds safe limits.
High‑strength brass body - Provides excellent durability and corrosion resistance.
Precision‑engineered spring mechanism - Ensures accurate and repeatable pressure release.
Thermal‑resistant seals - Maintain leak‑free performance under continuous temperature cycling.
OEM‑specific connection design - Guarantees correct fitment and reliable integration with Alpha boiler models.
