OPERATION AND MAINTENANCE
MODEL 415-1500 REGULATOR
GENERAL
The model 415 is a piston type, hand load regulator
available in outlet pressure ranges of 6000, 5000,
1500, and 400 PSI. It uses an unbalanced poppet
design for ruggedness and simplicity. There is a small
variation of control pressure with changing inlet
pressure as noted in the specifications. A 30 micron
filter in the poppet cartridge helps prevent damage by
contaminants.

ASSEMBLY PROCEDURE
1. Refer to drawing 415 cross section and assemble in
clean dry area.
2. Blow all parts clean.
3. Inspect sealing area of vent seat item 3 with 10X
magnification and remove any particles.
4. Install O ring 13 on piston 4.
5. Completely pack area between piston housing 5
and piston 4 with Cristo lub MCG 121 or 111 or
equivalent. Sufficient grease should be used so it
takes pressure to extrude grease out as piston is
inserted into housing. Wipe off excess.
6. Install O ring 14 with Cristolub 121 or 111 grease
and install seat item 3.
7. Apply Slick 50 or equivalent EP grease to bearings
10 and 11, screw 8 and threads in housing 7.
8. Install spring guide 6, bearings 10 and 11, and
spring 12 as shown.
9. Install preassembled poppet cartridge item 2,
preassembled piston housing and O ring 15 as shown.
Lubricate O rings and threads with Cristolub 121or 111
grease or equivalent.
10. Holding cap downward, assemble cap and body.
Torque to 20 to 30 ft lbs.
11. Install adjusting screw and knob with Slick 50
grease on threads.

INSTALLATION
Use a suitable pipe thread sealant such as
Teflon tape on inlet and outlet threads. Avoid
over torquing pipe thread. Normal torque
applied with a 6 or 8 inch long wrench is ample.
Use ample Teflon tape - 3 or 4 turns, not 1 or 2
turns. The inlet is on the left when facing the
adjusting knob with the two gage ports
upward. An optional panel mounting ring is
available (part no. 657). The ring clamps to the
cap portion of the regulator at any desired
location and orientation. The ring has two
threaded holes parallel to the regulator spaced
2.8" apart.
The regulator is NOT shipped

MAINTENANCE & REPAIR
CAUTION
-As with any regulator or valve,
particulates or moisture can plug or freeze the
internal filter or valve seat. This can occur when
up-stream dryers are not changed or remain
unused for long periods allowing corrosion
materials to accumulate. In critical applications
where it is important not to lose flow, a larger
particulate filter should be used upstream. Also
an orifice such as the Aqua model 796 should be
used downstream. This reduces the tendency to
freeze when moisture is present. Consult factory
for details.
The user should establish
intervals for changing the valve cartridge, filter and
upstream dryers based on experience and
service conditions. No representation is made
herein concerning such time intervals as each use
is unique. Back-up systems should be used in
very critical applications since field maintenance is
hard to insure. The poppet cartridge 832 is a
factory assembled item and should be replaced if
required and not disassembled unless absolutely
necessary.
Spare cartridges are available at a
nominal cost and should be kept on hand if rapid
repairs are required. IN ALL CASES THE UNIT
CAN BE RETURNED TO THE FACTORY OR
DEALER FOR REPAIR UNDER WARRANTY IF
APPLICABLE OR AT A NOMINAL CHARGE.
Maintenance or repairs should only be done by
qualified personnel in a clean environment by
following the drawings herein.
