The Altecnic Pressure Relief Valve delivers critical overpressure protection for domestic hot water systems and heating installations. Engineered to safeguard boilers, hot water cylinders, and system components from pressure-related damage. This valve operates at a pre-set 6 bar discharge pressure, automatically opening to release excess pressure to atmosphere when threshold levels are reached. The controlled discharge mechanism prevents dangerous pressure accumulation that could compromise equipment integrity or personnel safety. The WRAS-approved design ensures compliance with UK water regulations for residential and light commercial applications. The 1/2" BSP connection provides straightforward integration into existing heating and hot water systems. Features & Benefits: Automatic pressure relief at 6 bar set pressure protecting boilers and hot water cylinders. WRAS approved for compliance with UK water supply regulations. Safeguards system components from overpressure and potential catastrophic failure. Protects personnel in adjacent areas from pressure-related hazards. Suitable for domestic hot water systems, heating circuits, and boiler installations requiring overpressure protection. Connection: 1/2" BSP. Set Pressure: 6 Bar.
