High temperature switchbox
19 October 2015
Soldo Controls, the specialist manufacturer of position feedback devices in the Rotork Instruments Division, has introduced a high temperature extension to its LSB range of compact limit switchboxes for valves and dampers.
Manufactured with an aluminium or stainless steel enclosure, the new switchbox has been tested for operation in temperatures up to 250ºC for 2 hours or 300ºC for 70 minutes. High temperature applications include tunnel ventilation dampers, HVAC plant rooms and other building services environments.
Teflon coated stainless steel bushings ensure smooth and low friction shaft rotation, whilst precision end-of-travel switches guarantee normally open (NO) and normally closed (NC) logics.
