The Diaphragm Safety Valve for solar systems and water heaters is ideal for protecting all types of water heaters (solar and electric). When the pressure inside the water heater exceeds a specific value, the valve opens automatically.

The main reasons that the valve may activate include:

• High network pressure
• Overheating of the water

The installation of the valve always occurs at the cold water inlet and aims to:

• Control the inlet pressure of cold water into the water heater
• Prevent the return of hot water from the boiler to the cold water line
