Scope of the Manual
This manual provides instructions for the
installation, adjustment, and maintenance for
the types A-360 and A-361 pressure regulators.
DESCRIPTION
Types A-360 and A-361 pressure reducing and
regulating valves automatically reduce a high
inlet pressure to a lower delivery pressure and
maintain that lower pressure within reasonably
close limits, even during high flow rates.
Type A-360 is 2-way; Type A-361 is 4-way with
gauge taps on sides of body.

INSTALLATION INSTRUCTIONS
Types A-360 and A-361 regulators can
be installed in any position. For ease of
maintenance and repair however, it is
suggested that the valve be installed in a
horizontal line with the spring chamber upright.
For convenient operation and maintenance,
manual shut-off valves should be installed
upstream and downstream from the valve.
Before installing the valve, the piping should be
thoroughly flushed out to remove any foreign
material. Install the valve with the inlet pipe in
proper relationship to the flow arrow stamped
on the valve body.
OPERATING INSTRUCTIONS
Adjusting the Delivery Pressure
The regulator's delivery pressure setting is
adjusted by turning the adjusting screw (1) at
the top of the spring chamber after loosening
the adjusting screw lock nut (2). To increase
the delivery pressure, turn the adjusting
screw clockwise (into the spring chamber).
To decrease the delivery pressure, turn the
adjusting screw counter-clockwise (out of the
spring chamber). Tighten the adjusting screw
lock nut after the adjustment has been made.
NOTE:
When adjusting the delivery pressure, draw
flow and shutoff downstream to check
pressure set.
