The Caleffi 527760 safety valve is ideal for use in boilers, providing protection against excessive pressure. It is designed to be installed in central heating systems, offering a reliable solution to prevent risks associated with increased pressure. When the pressure exceeds the preset value, this valve opens to relieve the system, ensuring safe operation.

This two-port valve has two openings—one for the inlet of the medium and one for the outlet. When the inlet is closed, flow is interrupted, securing safety within your installations. By opening the inlet, the flow to the outlet equals that of the inlet, maintaining balance in the system.
