Specification
Reduce the risk of leakage in the whole house system
Prolong service life of pipeline system and water facility
When water is recharged after cutting off . The pressure is less than 0.1 Mpa(~1 bar). The relief valve will automatically exhaust to weak the water hammer effect.
Once the pressure exceeds 0.7 Mpa(~7bar), the relief valve will automatically release water and air and high-pressure loads caused by freezing.
Preventive Function
Water hammer / Over-pressure / Freezing
The built-in water hammer arrestor effectively buffer the pressure shock wave and suppress pipe vibration.
Sealed- normal pressure Exhaust- low pressure Relief- high pressure
