H. Spring (11)
Replace the spring if:
1. The ends are not ground flat and parallel.
2. The coils are bent, pitted or unevenly spaced.
3. The spring cannot be properly identified
(spring chart).
ATTENTION! !
19000 Series valve springs do not have sufficient wire
diameter to allow permanent spring marking.
The Set Pressure of the Consolidated 19000 series
valve should be within the spring range of the valve
spring. However if there is Constant Superimposed
Backpressure, the Cold Differential Test Pressure should
be within the Spring range of the Valve Spring. If the Cold
Differential Test pressure is only established because of
elevated temperature, then the Set Pressure should be
within the spring range of the valve spring and the valves
should be set at the Cold Differential Test Pressure.
I. Spring Washers (10)
Replace the spring washers if:
1. The bearing surface is galled, pitted or scratched.
2. Corrosion affects the centering of the spring.
J. Adjusting Screw (12)
Replace adjusting screw if:
1. Threads are torn, stripped or galled.
2. The bearing surfaces are galled, pitted or scratched.
3. The adjustment flats are damaged or rounded.
K. Bonnet Top (7)
The bonnet top should be replaced if:
1. The threads are stripped, torn or galled.
