Pressed steel 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.
