Relief Valve Inspection

• Remove the relief valve.

• Check to see if the steel ball inside the valve slides smoothly when pushing it in with a wooden or other soft rod, and see if it comes back to its seat by valve spring pressure.

NOTE

OInspect the valve in its assembled state. Disassembly and assembly may change the valve performance.

• If any rough spots are found during above inspection,
wash the valve clean in a high flash-point solvent and
blow out any foreign particles that may be in the valve
with compressed air.

Clean the parts in a well-ventilated area, and take care that there is no spark or flame anywhere near the working area. Because of the danger of highly flammable liquids, do not use gasoline or low flash -point solvents.

• If cleaning does not solve the problem, replace the relief
valve as an assembly. The relief valve is precision made
with no allowance for replacement of individual parts.
