The safety ball valve is a critical device for the safe operation of a boiler. It is designed to protect the central heating system from overpressure, thereby preventing serious risks to people and equipment. When the pressure exceeds a predetermined value, the valve automatically opens, allowing the system to decompress. It is installed at the highest point of the installation and operates without the intervention of any switch or handle.

This valve is double-port, which means it has two openings: one for the inlet of the medium and one for the outlet. When the inlet is closed, flow is interrupted, while when it is open, the flow to the outlet equals that at the inlet. It is ideal for use in boilers, providing safety and reliability during the operation of the heating system.
