Product Name: Keystone Figure 79U Pneumatic Actuator

Product Description

Features and benefits: - Compact rack and pinion design utilizes the whole piston area to develop output torque. Pistons with integral rack drive reduce the number of dynamic seals, minimizing air leakage. Double pistons nullify sideloads on the pinion shaft, minimizing bearing wear and extending life. Internal air porting eliminates external tubing. Hard anodized aluminum body with external electrostatic powder coating (ESPC) finish protects against corrosive environments. Female output drive enables direct mounting of most Keystone valves, eliminating special adaptation connections and assuring correct alignment. Bottom entry pinion shaft simplifies assembly and provides anti-blowout feature. Anti-friction piston pads ensure no metal-to-metal contact, providing smooth operation. Ideal for modulating or on/off control applications. Adjustable travel stops standard in both directions on sizes 065 through 091. An extensive range of standard accessories are available for direct mounting: - - Solenoid valves - Limit switchboxes - Positioners - Declutchable manual override gearbox - High visibility indicator General applications: - For remote control of any quarter-turn application; for example, ball, butterfly or rotary plug valves, dampers, etc. Technical data: - Max.
