Stainless Steel Actuators

Series 22/23

Flow Line Series 22 double acting and Series 23 spring return actuators are technically advanced stainless steel rack and pinion actuators. The Series 22/23 incorporates seven sizes ranging from 147 to 9462 in pounds. Features such as fine tooth rack and pinion. Internal travel stops and stainless steel hardware ensure the standard of performance expected from Flow Line Controls valve automation products.

Series 22/23 Stainless Steel Actuator Body

  • Cast stainless steel body machined to fine tolerances
  • Internal porting is standard eliminating any need for external tubing
  • Valve mounting is accomplished with ISO drillings on all sizes
  • Limit switch, positioner and solenoid valve mounting comply with Namur standards

Series 22/23 Stainless Steel Actuator Pinion

  • Pinions are machined from a single piece of stainless steel
  • Fine-tooth gears eliminate hysteresis and lost motion
  • ISO female drives are standard on all sizes
  • Bottom entry pinion provides anti-blowout protection

Series 22/23 Stainless Steel Actuator Pistons

  • Piston o-rings are held in place by a precisely machined groove matching the o-ring diameter
  • Internal RTFE piston guide precisely aligns the piston to the pinion to prevent piston roll

Series 22/23 Stainless Steel Actuator End Caps

  • Cast stainless steel end caps machined to fine tolerances
  • End cap o-rings are captive on all actuator sizes

Series 22/23 Stainless Steel Actuator Air Supply

  • All actuator sizes are equipped with 3/4" NPT supply ports
  • Supply pressure on all sizes is rated up to 147 psi air, hydraulic oil, or water depending on seals used

Series 22/23 Stainless Steel Actuator Bolts and Fasteners

  • All fasteners are stainless steel for corrosion resistance

Series 22/23 Stainless Steel Actuator Travel Stops

  • Internal travel stops allow ±5 degrees adjustment at both ends of stroke

Series 22/23 Stainless Steel Actuator Springs

  • Springs are stainless steel

Series 22/23 Stainless Steel Actuator Position Indicator

  • Functions as a visual indicator for 2-way valves and also for 3-way applications with a simple change of built-in indicator tabs
