Specification

Reduce the risk of leakage in the whole house system                                                                                 

Prolong service life of pipeline system and water facility

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

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.
