Advantages
This safety valve offers robust protection for residential and commercial water heating systems by effectively managing internal pressure.

When it may not be suitable
This valve is not suitable for systems requiring a rubber gasket, as it is designed for metal-to-metal sealing. Additionally, it should not be used in applications where the operating pressure consistently exceeds 8 Bar or where the temperature requirements fall outside the specified operational range.
Key specifications
Connection type: 1/2 inch outer thread and 1/2 inch internal thread
Maximum operating pressure: 8 Bar
Temperature regulation range: up to 120°C
Material: Steel
How to use
The valve should be installed at the cold water inlet of the water heater. Ensure that the thread connections are properly sealed using appropriate plumbing sealant or tape to prevent leaks. The valve must be oriented according to the flow direction indicated on the body to ensure correct pressure relief functionality. Regular inspection is recommended to ensure the valve remains free of debris and operates correctly.
What to consider before purchase
Verify that the 1/2 inch thread size matches your existing plumbing connections.
Ensure your system pressure does not exceed the 8 Bar limit.
Confirm that your installation does not require a rubber gasket, as this model does not include one.
Usage recommendations
Regularly check the valve for signs of leakage or corrosion. If the valve triggers frequently, it may indicate an issue with the water heater thermostat or the expansion vessel, and professional inspection is advised.
