The ½" safety valve from Caleffi is ideal for use in boilers, providing safety and protection to the heating system. It features a two-way design, meaning it has 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 outlet flow follows the same direction as the inlet. Its installation at the highest point of the heating system is critical, as it protects against dangerous pressure increases.
