Maintenance operations are simplified thanks to the automatic shut-off valve by shutting the water flow off when the valve is removed and also allow easy inspection of the air vent device.

Safety valves 311, 312, 313, 314, 513, 514 are built by Caleffi S.p.A. in compliance with the essential safety requirements set out in Directive 97/23/EC of the European Parliament and of the Council of the European Union, for the rapprochement of Member States in the field of pressure equipment.

Safety valves are typically used to control pressure on heat generators in heating systems, hot water accumulations in sanitary systems and water systems.

When the calibration pressure is reached, the valve opens and, by means of the exhaust into the atmosphere, prevents the pressure of the plant from reaching dangerous limits for the generator and for the components in the system.
