Control Valve Body: Inspection
- Clean all parts, except non-metallic check balls, thoroughly in clean solvent. Blow dry with compressed air.
- Inspect all valve and plunger bores for scores. Check all fluid passages for obstructions. Inspect all mating surfaces for burrs and scores. If necessary, use crocus cloth to polish valves and plungers. Avoid rounding sharp edges of valves and plungers with crocus cloth.
- Inspect all springs for distortion. Check all valves and plungers for free movement in their respective bores. Valves and plungers, when dry, should fall by their own weight in their respective bores. Roll manual valve on a flat surface to check for bending.
