motor operated double butterfly valves
The Envalve VK21 butterfly valves are designed to isolate or regulate flow. The double butterfly valves are made of PVC and have an EPDM gasket, which makes them resistant to many aggressive substances.
The 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.
