Inspection Procedure

    Object Number: 7628 Size: SH
  1. Inspect the valve body to spacer plate gasket for valve body channel witness marks. The witness marks should be complete. Incomplete witness marks may be caused by an uneven case surface. Incomplete witness marks may also be caused by cross-channel leaks.
  2. Inspect the valve body casting for the following conditions:
    3. • Porosity
    • Cracks
    • Damaged machined surfaces
    • Chips or debris

Cleaning Procedure
  1. Clean all the valves, springs, bushings, and the control valve body in clean solvent.
  2. Dry all the parts using compressed air.

Installation Procedure
