Manual operation
●
Handwheel made of aluminium
●
Handwheel with ball handle
Standard:
●
Handwheel made of GJL-200
●
Handwheel lockable
●
WSH limit switching device for signalling position and end positions
Options:
Primary reduction gearing
●
Type GZ as coaxial spur gear with various reduction ratios for reducing the input torques .
●
Combination with GK bevel gearbox directly on GS or on GS with GZ possible (90° deflection of input
shaft)
Primary reduction gearing
Valve attachment
Dimensions according to EN ISO 5211: The maximum torques of mounting flanges according to EN
ISO 5211 are to be met.
Valve attachment
●
With spigot
Standard:
●
With pilot bore
●
Worm gearbox can be mounted at 4 x 90° increments on coupling
Standard:
Splined coupling for connection to
the valve shaft
Finish machining with bore and keyway, square bore or two-flat with grub screw for secure
fixing to valve shaft.
Options:
Limit sensing for signalling position and end positions
●
WSG valve position indicator (hall sensors) for position and end position signalling to ensure precise
and low-backlash feedback for swing angles ranging between 82° and 98°.
●
WGD valve position indicator (counter gear mechanism) for position and end position signalling for
swing angles > 180°
