Altecnic / Caleffi Pressure Relief Valve 3/4" Loose Nut Connection x 1/2" F 6 Bar - A311501CST
The Altecnic / Caleffi Relief Valve - Nut Inlet - A311501CST is designed for use in domestic hot water systems, providing essential protection for hot water cylinders and heating systems, including boilers and associated components. This relief valve is carefully selected based on the required set pressure to ensure optimum performance. As pressure rises within the system, the valve opens when the discharge pressure threshold is met, releasing excess pressure into the atmosphere. This critical function helps prevent hazardous pressure levels that could endanger the boiler, hot water storage cylinder, and personnel in the surrounding area.
