Inspect
• The interior and exterior of all metal parts for
severe corrosion, pitting, and cracks. Replace as,
needed.
• All non-metallic components for cracks, wear, or
distortion. Replace as needed.
• The bores of the valve main body (51) and valve
cover (52) for deep scuffing or gouges. Replace as
needed.
Install or Connect (Figures 21 and 22)
