The Conoflow Full Reversal Positioner is used with springless piston or diaphragm
actuators. This unit utilizes a force-balance principle providing accurate positioning
of an actuator stem. The totally enclosed design allows use in various indoor or
outdoor environments.
This unit incorporates a two-stage pilot which offers stability, fast response and
excellent positioning accuracy. The spool valve section of the positioner permits
full reversal of the supply pressure to either actuator chamber allowing use of
maximum supply air pressure, thereby developing greater thrust.
Modified forms of this positioner offer direct or reverse acting modes of operation.
Refer to the chart below for details.
These Full Reversal positioners are adjustable for actuator stroke lengths of 1/4
to 10 (other strokes are available, consult the factory) and instrument spans of 6
to 24 PSI (41 to 166 kPa).
Performance of these positioners is backed by Conoflows years of experience as
a leading producer of precision instruments.
