1 Adjusting Knob controls outlet pressure setting - clockwise rotation increases and counterclockwise rotation decreases outlet pressure setting. 2 Regulating Spring is compressed when adjusting knob is rotated clockwise, which applies a downward force on top of flexible diaphragm. 3 Flexible Diaphragm and Valve Pin move downward, forcing Valve off the valve seat. Air flows past valve to downstream system. 4 Sensing Chamber - Pressure increases in downstream system and in the sensing chamber and applies an increasing upward force on the diaphragm bottom. The diaphragm, valve pin, and valve move upward, compressing the regulating spring. Upward movement stops when the forces below the diaphragm balance the forces above the diaphragm. When there is no downstream flow de- mand, the balance of forces occurs when the valve opens enough to compensate for demand, thus maintaining the desired outlet pressure. 5 Louvers - Air entering the filter/regulator is guided into a swirling pattern by the louvers. Coarse solid particles and liquids are forced to the bowl wall by centrifugal force and drop to the bottom. 6 Filter Element removes most solid particles. 7 Baffle creates a quiet zone at the bottom of the bowl and prevents air turbulence from picking up liquids and returning the liquids to the air stream.
