Page 8: Notes On Possible Severe Personal Injury
Risk of personal injury due to moving parts on the valve. During operation and when the solenoid valve is triggered, the actuator stem moves through its entire travel range. Injury to hands or fingers is possible if they are inserted into the valve. Î While the valve moves, do not insert hands or fingers into the valve yoke and do not touch any moving valve parts. EB 3969 EN... -
