Valve Positioners
3582 and 3582i Valve Positioners (for 657 and 667 Actuators)
The 3582 pneumatic and 3582i electro-pneumatic
valve positioners are accurate, efficient positioners
for use with 657 and 667 actuators.
The field-proven design is fast to respond to input
signal changes and is able to withstand the
vibrations of most plants.
Options . . .
J Gauges and J bypass valve for
direct-acting positioners using full input signal range.
