We offer hydraulic, electro-hydraulic, electric and pneumatic driven actuators. 

Our hydraulic actuators are both available with double acting design ( type GHA/D and single acting design with spring package ( type GHA/S)

Our butterfly valves are suitable for all liquids such as hot and cold water, seawater, sea cooling water, as well as oil and other neutral, non-aggressive fluids. They are available in cast iron, nodular cast iron, cast steel and bronze for pipes from DN 40 up to DN 800. The valves are absolutely sealed in both flow directions and require only little space in the pipe due to their compact mounting form. 

Quick closing valves and quick opening valves are used for sudden blocking or opening of piping systems in case of danger and on tanks with inflammable liquids.
