A position indicator with NAMUR mounting is atandard on all pneumatic actuator for. The hardened alloy steel pinion is precision ground and Nickel plated in order to reduce friction, provide maximum wear resistance. The aluminum extrusion is hard anodized to protect against wear and corrosion while reducing piston friction to absolute minimum. Epoxy coated die cast aluminum end caps provide maximum resistance potentially corrosive element. The precisely-balanced and hard anodized treatment die cast aluminum pistons are fitted with high quality rings and guides. The twin rack and piston design creates a constant torque output on all actuators. The high tensile steel springs are coated with Epoxy coated for long service.
