What is a good drive method for a DN200 butterfly valve? Is it difficult to open manually? If manual operation is not convenient, electric or turbine options can be used. I would like to know that an electric actuator is required for the electric option – is the turbine version smaller in size? The main consideration is ease of installation; I don’t want to connect cables or gas lines.
We don’t turn them on and off very frequently here, so we use manual controls; in larger places like boiler rooms, electric controls are used.
If not used frequently, manually operate directly； Frequent operation; add a turbine.
Can the DN200 one also be opened? If a turbine is used, what would its size be approximately, and by how much would the cost increase?
The DN200 butterfly valve is relatively easy to open; if precise control is not required, a turbine can be added. For many of our circulating water systems, butterfly valves are used; some with a diameter of 300 also use turbine valves
No problem; a DN200 butterfly valve can be fully operated using a manual turbine.
Using a turbine, what would the approximate volume be, and by how much would the cost increase?
Our unit is DN700 and it is electric. . . The valve opening time is approximately 90 seconds
