Compact combi switchbox valves with high air output
GEMÜ has added to its range of combi switchboxes and has adapted an existing type to enable a combi switchbox range to be available to meet specific requirements.
In comparison to external types, the integrated pilot valve is said to offer both functional and cost benefits, including fast reaction times, automatic programming of end positions and lower compressed air consumption.
The GEMÜ 4242 combi switchbox is now also available with an increased air output, which makes it possible to equip valves with a stroke of 2 to 75 mm with this product. The new size includes features of other products in the range, including a high visibility display and position indicator, interfaces such as AS-Interface, DeviceNet, IO-Link and 24V.
Both new GEMÜ 4240 and GEMÜ 4241 types work with mechanically adjustable sensors and are said to offer a cost-effective alternative compared to versions with electronic position detection. The proximity switches can be adjusted quickly and safely using a grid adjustment. In addition, this product type offers explosion protection approval in accordance with ATEX.
All combi switchboxes have a manual override to enable the activation of the valve without electronic support. This is especially helpful when performing servicing work.>
