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.

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.
