The Cherbros 3427/2 safety valve is ideal for boilers, providing essential protection for heating systems. Its installation ensures that any excess operating pressure is absorbed, opening automatically when the pressure exceeds the preset value. Its importance in installation is particularly critical, as it prevents serious risks that can arise from increased pressures. It is installed at the highest point of the system without the need for a switch or other valve.

This two-way valve features two ports: one for the inlet of the medium and one for the outlet. When the inlet is closed, the flow is interrupted, while when it is open, the flow into the inlet and outlet is the same, ensuring smooth operation of the system.
