5.2
Piston Outlet Valve, Ref. Figure 9
See Section 5.3 to service the diaphragm outlet valve.
5.2.1
All service on the outlet valve must be done with
the air off and the air supply locked-out and tagged-out.
5.2.2
Remove the control hose from the valve bonnet.
5.2.3
Use a large wrench to loosen the bonnet from
the valve body, until it can be removed by hand.
5.2.4
As the bonnet is removed, lift it straight up until
the piston stem clears the spindle.
5.2.5
Remove the spindle, plug assembly, and spring
from the valve body.
5.2.6
Remove the piston from the bonnet, by pulling
the piston stem.
5.2.7
Inspect all parts for wear and damage as
follows:
•
Inspect the valve plug washer, valve plug, and plug
retainer for damage. Replace all damaged parts.
When reassembling the valve plug assembly,
tighten the retainer enough to compress the washer,
but not so tight to cause it to bulge.
•
Examine the body casting for wear. If the body or
the machined seat is worn, replace the body.
•
Examine the spring guide-bolt and nylon washer. If
either is worn, replace both.
•
The spring is approximately 1-5/8
″
long, if it is
abrasive worn, rusted, or compressed, replace it.
•
The piston cup should fit snug against the bonnet’s
cylinder wall. If it does not, replace the piston
assembly.
•
The piston stem should be free of deep abrasion
and move freely in the spindle bore. If it is badly
abraded, drags in the bore, or loose in the bore,
replace the piston assembly.
5.2.8
Lubricate the cylinder wall and piston cup, with
lightweight machine oil or tool oil.
5.2.9
Install the piston into the bonnet cylinder.
Cocking the piston so it enters the bonnet at a slight
angle, and rotating it while applying pressure makes
assembly easier. Do not push the piston fully into the
bonnet; the stem should be even with the opening.
5.2.10
Place the spring over the guide-bolt, and place
the plug assembly (retainer down) on the spring.
5.2.11
Place the spindle in the body. The large opening
faces down, and fits over the plug fins. The spindle
shoulder will not rest on the valve body due to the force
of the spring.
5.2.12
To assemble the bonnet to the valve body, first
insert the piston stem into the spindle guide hole. While
keeping the bonnet, spindle, and body aligned, screw
the bonnet onto the body. If all parts are correctly
aligned, the body will screw-on hand tight until it is
seated.
NOTE: If the bonnet does not screw on hand tight,
do not force it. Recheck alignment and repeat.
5.2.13
After the bonnet is fully seated on the body,
tighten the assembly with a wrench.
5.2.14
Attach the control hose to the fitting on the
bonnet.
5.3
Diaphragm Outlet Valve, Ref. Figure 10
See Section 5.2 to service the piston outlet
valve.
5.3.1
All service on the outlet valve must be done with
the air off and the air supply locked-out and tagged-out.
5.3.2
Remove the cap by unscrewing the four cap
screws.
5.3.3
Remove the diaphragm and inspect it for
damage. Replace as necessary.
5.3.4
Inspect the seat in the body. If worn, replace the
body.
5.3.5
Reassemble in reverse order.
5.4 Abrasive
Trap
5.4.1
All service on the abrasive trap must be done
with the air off and the air supply locked-out and tagged-
out.
5.4.2
Clean abrasive trap screen and trap twice daily.
NOTE: Failure to clean the abrasive trap on a regular
basis is a major cause of system malfunction.
5.4.3
To check the abrasive trap screen, loosen the
top thumb screw and swing the lock bar off the cap, and
remove the cap.
5.4.4
Remove the screen and inspect it for wear and
blockage. Replace it when it is clogged or worn. Keep
spare screens on hand. Do not install the screen in the
trap until the bottom section of the trap is cleaned per
the following instructions.
