Keystone Figure 79U/E Pneumatic Actuator

Features

• Compact rack and pinion design utilising the whole piston area to develop output torque.
• Pistons with integral rack drive reducing the number of dynamic seals, minimising air leakage.
• Double pistons nullify sideloads on the pinion shaft, minimising bearing wear.
• Springs epoxy painted and colour coded for additional corrosion protection and ease of identification.
• Hard anodised aluminium body, with external ESPC finish, protects against corrosive environments including saliferous atmospheres.
• Alternative finish: electroless nickel plating.
• Female output drive enabling direct mounting in certain applications, thereby eliminating special connections and guaranteeing correct alignment.
• Bottom entry pinion shaft.
• Anti-friction piston pads ensuring no metal to metal contact, providing a smooth operation. Ideal for modulating or on/off control applications.
• Adjustable travel stops in both directions on certain models.
• Grease lubricated for life.
• ATEX certified II 2 GD.
