Cherbros safety valve is ideal for use in boilers. It is designed to protect hot water systems from potential overpressure. When the system's pressure exceeds a certain value, the valve opens to relieve the pressure, preventing risks to operation and safety. It is installed at the highest point of the system without the need for a switch or ball valve, ensuring effective operation. Its dual construction features two ports, one for the inlet of the medium and one for the outlet. Flow is interrupted when the inlet is closed, while it remains equal to the outlet when the inlet is open.
