GC31/GC34 Commandaire® Positioners

 GC31/GC34 Commandaire® Positioners
Product Description

Conoflow’s Commandaire® Positioner is a top mounted, integral positioner used with piston or spring and diaphragm actuators. Utilizing a force balance principle this unit provides proportional positioning of an actuator with stroke lengths up to 10”. The completely enclosed design eliminates exposed levers or linkages making the Commandaire® Positioner rugged and reliable.

Specifications

  • Supply Pressure Effect: Less than 0.15% per PSI
  • Power Amplification - (Proportional Band): Less than 5.0% deviation in signal or stroke produces full output pressure change
  • Ambient Temperature Range: -20°F to +150°F (-29°C to +66°C)
  • Flow Capacity (Dynamic): Up to 5.0 SCFM (0.14 m3/min) in either direction with a 100 PSI (690 kPa) supply
  • Air Consumption (Static): 0.3 SCFM at 40 PSI supply (0.008 m3/min at 276 kPa)
  • Air Supply: 20 PSI to 100 PSI (138 to 690 kPa)
  • Controller Signal: All standard spans and split ranges available.
  • Zero Suppression: 0 to 18 PSI (0 to 124 kPa)
  • Control Actions: Direct or reverse, top or bottom loading
  • Actuator Travels: 1/4" to 10" (6.35 to 254 mm)
  • Connections: 1/4" NPT
  • Adjustment: Zero adjust is external and can be made without tools.
  • Mounting: Mounted integrally to top of cylinder or spring and diaphragm actuator with 2-1/4" dimension between positioner mounting flange and actuator stem in retracted position.
  • Weight: Approximate Shipping Weight: 2-3/4 lbs. (1.25 Kg)

NOTE: Specifications are typical values based on the use of a Conoflow GB50 Series Actuator. Use of other actuators may affect performance
