C Type Pneumatic Actuator

CH-air C Type/ 01 Jan 2008

Competitive ATEX 4th Generation Actuator

Quick guide to the
CH-air C Type standard features : Externally adjustable end of travel adjustment
The CH-air C Type actuator is assembled using machined internal components which produces a finished product with a low friction coefficient. This produces an actua-tor that offers durability and reliability in service. The actuator is of rack and pinion design with an anti blow-out proof pinion, and its extruded aluminium body is hard anodized to protect it against oxidization in non-aggressive atmospheres. It is compliant with all the usual actuator norms making it compatible with similarly compliant valves, and position monitoring, control and feedback devices. The C Type is of the 4th generation design whereby the end of travel adjustments can be made externally for both open and closed positions. This is achieved with lock-able adjusting bolts striking an internal cam. Safety is a key feature, particularly in spring return models, where the use of pre-loaded spring capsules which fully relax before the actuator’s end cap is removed, protect engi-neers when servicing the actuator. An impressive 13 models make up the range of the aluminium version, offering a maxi-mum double acting torque output of 3500Nm at 6 bar air supply, and 1300Nm end of spring torque for the largest spring return model, based on 6 bar air supply. The C Type actuators are CE marked and ATEX approved making them safe to install in hazardous atmospheres. Robust rack and pinion con- struction ATEX Ex II 2 GD Approved for use in hazardous areas CE Marked Hard anodised aluminium body Safe to dismantle for routine maintenance Compliant with all actuator standards Position feedback and control devices are quick and easy to mount.
In all but the smallest and largest actuator sizes, the actuator has dual ISO:5211 drill-ings and a double square drive, making the mounting of the C Type actuators flexible and easy.
