IR series precision regulators adopt a mechanism called a nozzle flapper.
The nozzle flapper controls the back pressure in the pilot chamber by opening and closing the nozzle on the outlet side against the compressed air flowing into the pilot chamber for operating the main valve. It is used for pressure setting.
In this way, the compressed air supplied to the product is constantly flowing into the pilot room in this mechanism, so air is continuously released to the outside even when the pressure at the outlet is not set. This released air is called bleed, and the majority of the air consumption listed in the catalog is bleed air consumption.
Note that bleed is a phenomenon associated with the nozzle flapper, which is separate from the relief action (action to depressurize when the set pressure rises too much).
Note 1) Be sure to use a mist separator in addition to the filters on the inlet side of IR1000/2000/3000 series regulators.
Note 2) Use a mist separator in addition to the filters on the inlet side of new IR1000-A/2000-A/3000-A series regulators if needed.
