Recommended solution: Fitting with sensors Go-Switch

is the result of careful planning and experience in position control valves. Through the choice of materials, workmanship and quality treatment, CE srl guarantees: Reliability Impacts sturdiness High resistance to atmospheric and chemical events High protection in hazardous areas (Exd - Exi) Precision in indicating the position of the valve Rapid sensor adjustment Wide choice of configurations and custom solutions

During the design of the housing, our primary goal was to create a product capable of satisfying the most severe applications for petrochemical, chemical, refinery, oil & gas, power generation and water treatment. Therefore, particular care has been given to the choice of the material as well as to special the treatments to the material it self to obtain the highest level of protection against aggressive ambience typically present in the above applications. All housings series CF are manufactured with aluminium alloy with a very low copper content ( <= 0.1%) which, combined with the special chromate conversion coatings treatment and polyester painting process, guarantees an excellent protection against corrosive and aggressive agents typically present in the industrial environments. For applications in particularly severe environments, such as very low temperature and/or very high corrosion, we have a solution of 316L SST made housings with a special treatment of electropolishing.

We have improved the design of the housing by minimizing the maintenance lead times as well as the set up and fine tuning timing; this was also obtained with the “direct screw in” covers which do not require fixing screws, and without the necessity of removal of the three-dimensional (3D) visual position indicator. The set-up of the proximity sensor for open/closed position of the valves, thanks to the new internal actuation device, is completed quickly and very precisely, by an easy manual pressing on the actuation vanes inserted into the reference multi-marks sector with selectable position of 2° Furthermore, the new internal actuation device, con be provided with a third sensor and vane to control the intermediate position of the valve (partial stroke), with different test range. The set-up of the mechanical lever micro switches is performed with the regulation of traditional camme devices.

The housings series CF are available in the ATEX version (directive 94/9/CE) with the equipment. certification CE, Ex II 2 GD as they have an explosion-proof method of protection Exd/Exia IIC T6,T5,T4 Ex tD A21 IP66 T85/T100 /T135°C for ambient operating temperature from - 60°C to a maximum of + 100°C. The above-mentioned housings can also be used in plants classified as: GROUP II (surface plants) zone 1 / zone 21 (with redundancy ), zone 2 / zone 22. The level of protection IP 66/67 makes the housing totally protected against dust and water jets similar to waves. Also available with IECEx and GOST R Ex certified.
