The Mestriner safety valve is extremely suitable for boiler applications, ensuring the safety of the heating system. It is designed to prevent excessive pressure that may occur during operation by automatically opening when the pressure exceeds a predetermined value. Regarding installation, it is recommended to be installed at the highest point of the system to achieve maximum efficiency and protection.

It is two-way, meaning it has two ports: one for the medium's inlet and one for the outlet. When the inlet is closed, it stops the flow, while when it is open, the flow at the outlet equals that of the inlet.
