The new GP range of coaxial gearboxes allows manual valve operation or automation via an actuator, that is mounted by means of an adapter flange. The illustrated versions (photo) are equipped with handwheel and square for power-tool operation. GP gearboxes can be used to operate gate and globe valves, but also partial-turn valves like butterfly valves and ball valves. Coaxial design allows centered gearbox mounting onto valve flange and avoids radial force impact to the valve. The gearboxes are available in four sizes with three reduction ratios each, and cover the torque range between 100 and 2,500 N-m. Reduction ratios are implemented by planetary gearings. — AUMA Riester GmbH & Co. KG, Muellheim, Germany
