The 4" safety valve from Watts is ideal for installation on boilers. Designed to protect the central heating system from potential excessive pressure. When the pressure exceeds the set limit, the valve automatically opens, allowing for depressurization and preventing serious risks to people and equipment. It is installed at the highest point of the setup, without the need for switches or valves, providing immediate operation.
The two-way design of the valve includes two ports: one for the inlet of the medium and one for the outlet. Utilizing this feature, the flow is effectively controlled – when the inlet is closed, the flow is interrupted, while when it is open, the flow remains steady through both ports.
