29 Class 1 Valve Manual
p/n: 119138
• Remove both valve seals and visually inspect them for foreign debris, deterioration, or damage (cracks,
splits, flat spots, etc), especially around the valve ball / seal interface. Replace parts as necessary.
• Remove the valve ball and visually inspect the outer surface for scratches or marks that would prevent
full contact with the valve seal. Replace the ball if necessary.
CONDITION: Valve does not fully OPEN or CLOSE – manual operation.
REMEDY:
• Inspect the actuator lever or handle for proper installation on the valve stem. (The valve must open or
close fully before the stop plate makes contact with the valve body.) Adjust handle orientation as
needed.
• Inspect the valve ball and valve seals for foreign debris, deterioration, or damage that could cause
interference between the valve ball and seals or body.
If you require replacement parts for your Class 1 valve, please order the
appropriate repair kit, shown in Section 6.4.
