Pressure relief valve and pressure relief valve for high pressure fan. Used to adjust the fan operating pressure, prevent the fan operation overload.

Rv-01 Regulating pressure 0-300mbar (0-30kpa)

Rv-02 Adjustable pressure 300-600mbar (30-60 kpa)

Principle of high-pressure fan pressure relief valve:

  Installed on the air inlet and outlet, when the pressure exceeds the pressure value set by the high pressure fan, or the fluctuation of pressure in the high pressure fan exceeds the set value, the relief valve will be immediately opened in 0.2 seconds, and the excess pressure will be released through the air flow. So as to protect the high-pressure fan, when the pressure in the high-pressure fan drops to the safe value, the valve is slowly closed, will not cause the second high-pressure fan pressure fluctuation. The valve body is plastic outside and steel net inside, resistant to acid, moisture and corrosion.
