The Herz 3-way Hot Water Valve Calis-ts is ideal for use in boilers, providing safety and reliability to your central heating system. Equipped with a safety feature, this valve ensures you are protected from potential overpressure during operation by automatically opening when the pressure exceeds the preset value. This helps prevent serious risks to people and surrounding materials.

It is a two-way valve, meaning it has two ports: one for the inlet of the medium and one for the outlet. This allows you to control the flow easily, as the flow at the outlet corresponds to the flow at the inlet when it is open. The valve is installed at the highest point of the system, ensuring its effective operation without the need for switches or other controls.
