3 Filter Regulator Series IW Principle of Operation Handle q Adjusting spring w Exhaust port Diaphragm e EXH&BLEED Inlet valve r Filter (Sintered metal)t Drain cock Air flow from the inlet passes through filter (sintered metal) t where solids are removed. When handle q is adjusted downwards, adjusting spring w is compressed. The inlet valve r is opened allowing air flow to the outlet. Air outlet pressure balances against diaphragm e and adjusting spring w. When the outlet pressure is higher than the set pressure, the inlet valve r is closed and exhaust of the excess outlet pressure takes place through the adjusting spring cover bleed. This ensures constant outlet pressure is maintained.
