Valve Body: Service and Repair
Cleaning
1. Clean all parts thoroughly in clean solvent and blow dry with moisture-free compressed air.
2. Inspect all valve and plug bores for scores. Check all fluid passages for obstructions. Inspect the check valve for free movement. Inspect all mating
surfaces for burrs or distortion. Inspect all plugs and valves for burrs or scores. Replace the control valve body if the bores or valve are scored
beyond the point of being cleanable.
3. Inspect all springs for distortion. Check all valves and plugs for free movement in their respective bores. Valves and plugs, when dry, must fall
from their own weight into their respective bores.
CAUTION: Do not sand, stone or polish valves and bores. This removes the anodizing treatment and destroys them.
4. Roll the manual valve on a flat surface to check for a bent condition.
