AV-800 Series Adapter Installation Considerations

1. TAC actuator and adapter dimensions may need to be checked to assure proper clearances are maintained.

2. The replacement actuator and adapter listed represent what TAC believes are an equivalent. Actuators do not

necessarily have the same physical size, range, wire codes, terminations, electrical ratings, etc. as the original

actuator. The emphasis has been placed on providing a replacement actuator of similar specifications to meet

the valve and system requirements. The user must determine the substitution acceptability by reviewing the

valve specifications, actuator specifications, and the application. When an actuator is replaced, make sure that

the capacity of the replacement unit will meet the requirements of the valve it is being mounted on and the sys-

tem in which it is being used.

Caution: For proper operation, make sure the stroke of the selected TAC actuator is equal to or greater than that

of the competitive valve.

3. TAC assumes no responsibility for guaranteeing the acceptability of any suggested replacements. The

suggestions contained herein should only be used as a guide.

4. Consult the valve manufacturer if the system pressures or temperatures are being changed to assure proper

performance.

5. Pneumatic actuator close-offs are based on 20 psig to the actuator diaphragm

6. All specified close-offs are nominal, and can vary based on the age of the valve, tightness of the stem packing,

and variations in stem drag
