COMMERCIAL CONTROLS Pneumatics

Pneumatic Piston Actuators • Multipurpose positioning device that operates ventilating dampers in response to output signals from a pneumatic controller • Two-way swivel connection on cylinder head insures non-binding movement • Telescoping piston rod allows easy linkage to damper attachment points up to 8-3/4" away from actuator face • Includes swivel ball joint and slotted crank arm connector for optional damper linkage methods • Provides two positions on pivot post allowing direct actuation force on linkage not

perpendicular or parallel to actuator mounting plane • L86-277 comes with L38-313 positioner kit to enable sequential or two-stage actuator control (see below) Specifications: • Spring range: 8–13 PSIG • Maximum actuator force 8–13 PSIG: 105 lbs. power stroke, 120 lbs. return stroke • Air connection: Barb for 5/32" or 1/4" O.D. poly tubing WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov
