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.
