Function: The rotary motion of the threaded spindle is converted into a linear motion of the pressure tube. Due to the piston rod principle, high axial forces can be realised, e. g. for shelf and dosing applications. Spindle and piston rod are aligned parallel.
The products can be used as follows, according to the marking:
a) In Zone 2 (Gas, Category 3G, EPL Gc) in explosion groups IIA and IIB
b) In Zone 1 (Gas, Category 2G, EPL Gb) in explosion groups IIA and IIB
The qualification with regard to the surface temperature is T4; for all gases, vapours and mists with an ignition temperature > 125 °C the product is not an ignition source.
