The safety valve from Cherbros is ideal for use with boilers, providing protection against excessive operating pressure. When the pressure exceeds a specified value, the valve automatically opens, relieving the system and preventing risks to people and materials. It is installed at the highest point of the system and operates without the need for a switch or ball valve.

The dual-design of the valve includes two ports: one for the medium's inlet and one for the outlet. When the inlet is closed, flow is interrupted, while when it is open, the flow at the outlet equals that at the inlet, ensuring optimal system operation.
