The ATV 556 thermostatic valve is specially designed for use in boilers, providing safe and efficient operation. This safety valve increases the protection of the central heating system from excessive pressure. When the pressure exceeds the set value, it automatically opens to relieve the system, ensuring safety for both people and materials. It is easily installed at the highest point of the setup, without the need for additional switches or drains.
The valve is double-ported, featuring two ports, one for the inlet of the medium and one for the outlet. If the inlet is closed, the flow is interrupted, while when it is open, the flow at the inlet is the same as at the outlet. With a maximum operating temperature of 60°C, it is ideal for most heating applications.
