The Caleffi Safety Divert Valve is suitable for use in boilers, providing protection to the central heating system from overpressure. When the pressure exceeds a preset value, the valve automatically opens to relieve the system, ensuring its safe operation. Proper installation of the valve at the highest point of the setup is critical, as it does not require a switch or a drain valve.

The valve's double-port design offers two connections: one for the input medium and one for the outlet. This allows for flow interruption when the inlet is closed and maintains the same flow through the outlet when the inlet is open. This ensures system stability and safety.
