Motor- and Gearbox Valves

If the valves are installed behind a concrete protection wall an operation with bevel gearbox or, for smaller valves with simple stem extension can be the solution.

As an alternative, if a slow opening and closing is required, the automatic operation can be performed with electric motor drive.
Especially for long-distance pipelines with valves distant from the control centre this is quite a common solution.
