Manually operated valves
Up to nominal size DN 65 manually operated valves can be operated either with hand lever or with rising hand wheel. DN 80 is operated with a rising hand wheel, too. As an option it can be designed with a rising stem. For bigger valves starting from DN 100 up to DN 400 a simple non-rising hand wheel with rising stem can be used.
Due to the low operation torques there’s no need to use an additional gear box. For an operation from behind a safety barrier a design with gear box or simple stem extension is possible though.
