The Watts Diode Safety Valve is ideal for use in boilers and is a key safety component for the central heating system. This valve is designed to open automatically when the system pressure exceeds a predetermined value, thus relieving the system and reducing risks to both people and materials. It is installed at the highest point of the installation, ensuring it operates without the need for a switch or valve.

Its diode construction offers two ports, one for inlet and one for outlet, allowing flow under smooth and safe conditions. When the inlet is closed, the flow is interrupted, while with the inlet open, the flow remains stable at the outlet. This valve is essential to ensure the safety and proper operation of your boiler room.
