Accurate Valve Positioning
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.
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.
- 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.
