More information
The VDEG Envalve VK21 butterfly valves consist of two valves and one motor. The run times of the valves range from 36 to 90 seconds (depending on the type) through a rotational angle of 90 degrees. They have a large throughput capacity and bi-directional flow. The electric motor means that the valves can be operated remotely. The motor has a supply voltage of 24VAC/DC as standard, but a 230V version is also available on request.
