ders to move the rack and rotate the valve. Located on
the end of the cylinders are adjusting screws which limit
the travel of the actuator. When looking at the rear of
the compressor, the adjusting screw on the right on the
compressor adjusts the fully closed (full load) position
of the valve. The full load position of the actuator may
be checked by removing the adjusting screw at the
unloaded end of the actuator (left side of the compres-
sor) and using a rod to push the pistons to the full load
position. The rod must be clean and free of burrs and
scale. Take care not to scrape the cylinder walls when
moving the pistons.

Minimum Discharge Pressure/Check Valve
(FIGURE
1–5, page 3, and FIGURE 4–6, and
FIGURE 4–7) – An internal spring–loaded minimum
pressure/check valve is used in the final discharge line
to provide a positive pressure on the oil system of the
compressor even when the air service valve is fully
open. The check valve portion of the valve prevents
backflow of air from the shop air line when the unit
stops, unloads or is shutdown.
The minimum pressure valve incorporates a spring–
loaded piston which maintains approximately 65 psig in
