 Positioner
Series
5000
Electro/pneumatic
or Pneumatic
The Posi-flate Series 5000 Positioner provides
accurate valve positioning with advanced features. It may be
used with 3-15 PSI pneumatic control signals (as shown), or fitted
with one of three current-to-pressure transducers for 4-20 mA
signal inputs. The pneumatic positioner is available with many
options including limit switches, position feedback transmitter
and a visual dome indicator.
Applications
A high spool valve, plus an adjustable gain system, make the pneumatic positioner well suited for use with all pneumatic rotary actuator types including rack-and-pinion, heavy duty and others.
The positioner housing is constructed from durable die-cast aluminum and treated with a dichromate undercoat and polyester powder top coat for protection against the toughest applications in all process industries.
Features
- Non-interactive span adjustment. Reduces
calibration time.
- Adjustable gain. Allows positioner sensitivity
adjustment without removing or replacing components.
- Corrosion-resistant materials. All exposed
parts are constructed of heavy-duty anodized aluminum.
- Captive cover screws. Permits calibration
without potential for losing screws.
- Optional visual dome indicator. Provides
fully adjustable, high-contrast, full-angle viewing of valve
position.
- Field upgradable - to any of three electro-pneumatic
options without removing the cover. Switches or a position transmitter
can be installed in the field by replacing the shaft and adding
modular cards.
- Vibration resistant. Low spool mass, outboard
spool bearings and locking calibration adjustments provide reliable
operation under high vibration.
