Valve Body: Service and Repair
Cleaning and Inspection
CLEANING
Clean the valve housings, valves, plugs, springs, and separator plates with a standard parts cleaning solution only. Do not use gasoline, kerosene, or
any type of caustic solution. (Fig. 128)
Do not immerse any of the electrical components in cleaning solution. Clean the electrical components by wiping them off with dry shop towels only.
Dry all except the electrical parts with compressed air. Make sure all passages are clean and free from obstructions. Do not use rags or shop towels to
dry or wipe off valve body components. Lint from these materials can stick to valve body parts, interfere with valve operation, and clog filters and
fluid passages.
INSPECTION
Inspect all of the valve body mating surfaces for scratches, nicks, burrs, or distortion. Use a straightedge to check surface flatness. Minor scratches
may be removed with crocus cloth using only very light pressure.
Minor distortion of a valve body mating surface may be corrected by smoothing the surface with a sheet of crocus cloth. Position the crocus cloth on a
surface plate, sheet of plate glass or equally flat surface. If distortion is severe or any surfaces are heavily scored, the valve body will have to be
replaced.
