Handwheels GN 227.7 feature high mechanical strength and a coating for increased corrosion resistance. They are also not affected by shock and knocks.
The conical square hole allows easy installation and firm seating on a spindle. The cast shape prevents injuries from sharp edges during handling. The engraved labels “SHUT” and “OPEN” help with safe and correct operation of the valves.
