The A-4000-138 Remote
Mounted 3/8 in. Pressure
Reducing Station (see Fig. 9)
comes completely assembled
with a wall mounting bracket,
0 to 30 PSIG gauge, safety relief
valve, and 3/8 in. O.D.
compression elbow fittings on
the high and low pressure sides.
The desired output pressure can
be easily adjusted between 0
and 30 PSIG using the black
knob. The factory set safety
relief valve relieves
overpressures exceeding
25 PSIG (175 kPa). Pressure
adjustments up to 50 PSIG (350
kPa) can be made; however, the
0 to 30 PSIG gauge must be
replaced with one having a
higher scale and the safety relief
valve must be readjusted to the
required higher value. Designed
to handle input pressures up to
300 PSIG (2100 kPa) at air flows
in excess of 20 SCFM (9.4 L/s),
this pressure reducing station
regulated an output pressure
within a 0.2 PSI (1.4 kPa)
variation with a 20 PSI (140 kPa)
variation in input pressure.
