GB50/GB55 Series Pneumatic Piston Actuators

GB50/GB55 Series Pneumatic Piston Actuators
Product Description

Conoflow’s Pneumatic Piston Actuators are compact units designed to function in today’s high performance instrument systems. Piston diameters of 3” to 12.5” are available with standard strokes up to 10” (for stroke lengths greater than 10”, consult the factory). Integral positioners are standard for modulating service.

Force produced is a function of the supply pressure which can be varied from 20 to 100 PSI (138 to 690 kPa). Fast stroking speeds are made possible through the use of a high capacity positioner coupled with a unique cushion-loading regulator. The GB50 Series Piston Actuators are designed for use in corrosive atmospheres or adverse weather conditions.

Datasheets

Specifications

  • Piston Diameter: see data sheet for details
  • Effective Area: see data sheet for details
  • Stroke Length: 1/4” to 10”. Longer strokes are available, consult the factory.
  • Supply Pressure: 20 to 100 PSI (138 to 690 kPa)
  • Air Consumption w/Positioner:
    • Static: 0.30 SCFM (0.008 m3/min) at 40 PSI (275 kPa) supply
    • Dynamic: 5 SCFM (0.142 m3/min) (max) at 100 PSI (690 kPa) supply
  • Thrust: Thrust, T, equals the product of piston effective area, A, multiplied by supply pressure differential, ∆P, [up to 100 PSI (690 kPa)]. T=(A)∆P. Example: Develop the thrust of a GB51 actuator with a 100 PSI (690 kPa) supply and a 20 PSI (138 kPa) cushion load. 12 in2 x 80 PSI = 960 lbs. (77.42 cm2 x 551 kPa = 435 Kg) of thrust.
  • Positioner: Suitable for all standard instrument air signals; direct or reverse acting, top or bottom loading
  • Standard Accessories: Integrally piped cushion-loading regulator and gauge (for units with positioners only)
  • Approximate Shipping Weight: see data sheet for details

Materials of Construction

Cylinder: Aluminum
Piston: Aluminum
Stem: 303 Stainless Steel
