3) Install the 1st stage regulator on the cylinder. Ensure
the relief valve and intermediate pressure gauge are
attached to low-pressure ports.
4) Wet the relief valve with soapy water to help indi-
cate gas flow
5) Slowly bring up air pressure while watching the
intermediate pressure gauge until the pressure gauge
indicates 180- 200 p.s.i.g. (12.40-13.78 bar). If the re-
lief valve starts venting at a pressure below 180- 200
p.s.i.g. (12.40-13.78 bar), secure the air supply and
adjust the adjustment screw (1) in (clockwise) 1/8th
turn. Slowly bring up pressure and recheck.
Continue this procedure as necessary until the relief
valve consistently vents at a pressure between 180-
200 p.s.i.g. (12.40-13.78 bar). If the valve does not
start venting when the gauge reads 200 p.s.i.g. (13.78
bar), slowly back out on the adjustment screw (coun-
ter clockwise) until the valve starts venting, forming
bubbles in the soap solution.
6) After the valve has been adjusted, adjust the 1st
stage regulator intermediate setting to 135 p.s.i.g.
(9.3 bar), re-wet the valve, then slowly increase the
intermediate pressure on the 1st stage regulator one
last time to recheck the lift pressure. The valve should
start forming bubbles or venting at between 180- 200
p.s.i.g. (12.40-13.78 bar).
7) After final lift check reset the regulator to the ap-
propriate over bottom setting. Remove the intermedi-
ate pressure gauge.
TROUBLESHOOTING
Problem: Valve pops open and will not stop flowing:
Check: If while setting the relief/bleed valve the valve
pops open and will not stop flowing, secure the air
supply valve and allow the valve to reseat. Try the
procedure again, ensuring that the supply valve is only
slightly cracked open, allowing full test pressure but
minimizing high flow potential.
Problem: After resetting the first stage to 135 p.s.i.g.
(9.3 bar), the valve continues to leak:
Check: This indicates the valve body, seating surface
or the soft seat is either dirty or damaged. Usually,
cleaning both the metal body, seating surface in the
116
valve body and the soft seat will fix the problem.
If, after cleaning, the problem persists, replace the
soft seat and spring and retest the unit. If the seat
continues to leak, then replacement of the complete
valve will be necessary.
The purpose of lift checking the valve is to ensure
the relief operates properly allowing excess pressure
to escape in the event the first stage develops a slight
leak. This procedure also explains the steps necessary
for readjusting after cleaning or overhaul.
