ASSEMBLY (cont.)
1.
Install stop (31), dowel (30) and
new preformed packing (29) in
body (32, Figure 14-108).
NOTE
To change pressure on springs, spacers must be changed.
Spacer 5M3492 is 0.010 inch thick and will change
pressure 2.01 psi. Spacer 7M1396 is 0.062 inch thick and
will change pressure 12.5 psi. Spacer 7M1397 is 0.036 inch
thick and will change pressure 7.25 psi. Adding spacers will
increase pressure required to open valve and subtracting
will reduce pressure requirement.
2.
Install six spacers (28), spacer (27), springs (26 and 25)
and piston (24, Figure 14-107).
3.
Install spool (23) and spring (22, Figure 14-106).
4.
Install new preformed packing (21) in cover (20).
