Product Description
1.
The F10 positioner provides the means for a pneu-
matic actuator to be positioned to any point between
full open and full closed position. This allows accu-
rate setting of rotary and linear control valves as
well as a wide range of dampers and similar de-
vices. The actuator’s movement is controlled in
proportion to a 0.2 to 1 bar (3-15 psi) incoming
pressure signal.
The Posiflex F10 positioner provides:
- A single model covers both single acting and
double acting actuators.
- External Zero Adjustment.
- High accuracy due to “high gain” amplification.
- Four Position Cam for Linear Actuators
provides for linear, quick opening, equal per-
centage and split range characteristics.
- Three Position Cam for Rotary Actuators
provides for linear, quick opening and equal
percentage characteristics. A special cam for
rotary actuator provides for split range.
- Direct or Reverse Acting.
F 10 positioners are available for both rotary and
linear applications and because of the standard-
ized mounting interface (VDI/VDE 3845 or IEC 534/
6), installation is simple and trouble free. Mounting
kits are available for most actuator types.
The purely Pneumatic mode of operation means
that F10 positioners may be used in explosion
hazardous areas without any additional protection
being necessary.
A wide range of modular control options are avail-
able: These cover the addition of gauges, indicat-
ing switches, position transmitters, etc.
