Actuators

Pneumatic Actuator: Rack and Pinion Design Construction, Double Acting, Spring Return

Features:

Indicator - A position indicator with Namur mounting is standard on all OVC pneumatic actuators for mounting accessories.
Pinion - The hardened alloy steel pinion is precision ground and Nickle plated (over 24um)in order to reduce friction, provide maximum wear resistance. Full conformance with newest standards of ISO5211 & DIN3337. The dimensions can be customized and as options stainless steel and aluminum are also available.
Actuator Body - The aluminum extrusion is hard anodized (over 30um) to protect against wear and corrosion while reducing piston friction to the absolute minimum. Other option such as Nickel plating,PTFE and power polyester painting are available.
End Caps - Epoxy coated (over 200um) die cast aluminum end caps provide maximum resistance against potentially corrosive elements other treatments such as Nickle plating & PTFE painting are available.
Pistons - The precisely-balanced and hard anodized treatment (over 30 um) die cast aluminum pistons are fitted with high quality rings and guides.the twin rack and piston design created a constant torque output on all actuators.
Travel Adjustment - The standard adjustment is +/-5 in both the open closed positions through easily accessible external adjustment bolts.
High Performance Springs - The high tensile steel springs are coated with zinc phosphate for corrosion resistance and longer service. The pre-loaded springs can be safely & rapidly disassembled.
Bearings & Guide - The highly durable compound material provides high trust stability with minimum friction and long life.
O-Rings - NBR O-rings provides trouble-free operation at standard temperature ranges.Viton and Silicone O-rings are available for high or low temperature applications.
