The 3/4-inch by-pass pressure relief valve by Caleffi is a reliable choice for radiators. Designed to be installed in a central heating system, it protects against excessive pressure that may occur. When the pressure exceeds safe limits, the valve opens automatically, allowing excess pressure to be released and ensuring the system operates safely.
The valve is double-actuated, meaning it has two ports, which at any time allows for smooth flow of the medium. If the inlet is closed, flow stops; when open, the inlet flow equals the outlet flow. It is installed at the highest point of the setup without the need for switches or valves. Lastly, the valve has a diameter of ¾", making it ideal for your application.
