CLA-VAL 100-01 HYTROL Valves operate with maximum efficiency when mounted in horizontal piping with the cover UP, however, other positions are acceptable. Due to size and weight of the cover and internal components of 8 inch and larger valves, installation with the cover UP is advisable.

  • Page 13 MAINTENANCE PREVENTATIVE MAINTENANCE The CLA-VAL Model 100-01 HYTROL Valve requires no lubrication or packing and a minimum of maintenance. However, a periodic inspection schedule should be established to determine how the operating conditions of the system are affecting the valve. The effect of these actions must be determined by inspection.

On 8” and larger valves there are 4 holes (5/8” - 11 size) where jacking screws and/or eye bolts may be inserted for lifting purposes.
  • Page 15 CLA-VAL 100-01 Installation - Operation - Maintenance NGE - GE - AE INSPECTION OF PARTS After the valve has been disassembled, each part should be examined carefully for signs of wear, corrosion, or any other abnormal condition. Usually, it is a good idea to replace the rubber parts (diaphragm and disc) unless they are free of signs of wear.
