 D941X Electric Soft Sealed Flange Butterfly Valve

 

D941X electric soft-seal flange butterfly valve is a new generation of speed-regulating butterfly valve. This valve has changed the traditional mode of changing the speed of butterfly plate switch by mechanical speed change from the design idea. According to the action characteristics of different positions of butterfly plate, a brand-new design has been made from the electric drive control. This series of butterfly valves adopt to change the frequency of input current of electric device, and then adjust the rotational speed and output torque of electric device, so as to control the speed of butterfly plate start-up and shut-down, and realize the purpose of butterfly plate fast-closing, slow-closing or slow-opening and fast-opening. It has the same function as the hydraulic butterfly valve.

 

Application of D941X Electric Soft Sealed Flange Butterfly Valve

 

This valve is suitable for outlet position of pump in pipeline with medium of water and sea water. It has the characteristics of both closed-circuit valve and check valve. It can avoid and reduce backflow of medium in pipeline system and water hammer impact, and protect pipeline. It is especially suitable for power plants and water plants where working power supply is very reliable.

 

3. Characteristics of D941X Electric Soft Sealed Flange Butterfly Valve

 

1. Electric starting and closing, with arbitrary adjustment, check and cut-off functions. Easy to operate, safe and reliable.

 

2. The valve can realize the action of slow opening, fast opening, fast closing and slow closing continuously, and effectively prevent the medium backflow at the outlet of the pump and the production of water hammer.

 

3. Energy-saving drive, the same drive motor as the ordinary butterfly valve, can realize the functions of high speed, small torque in fast-closing section and large torque in slow-closing section.

 

4. Installed at the outlet of the pump, the butterfly valve has the common function of check ah and gate valve at the same time, so it can replace two valves with one valve, save installation space and save the cost of pipeline network.

 

5. the flow resistance is small. When the valve is fully open, the flow resistance coefficient does not exceed 0.3, so the energy can be saved and the running cost of the pipeline can be reduced.

 

6. When an accident or power failure occurs, butterfly valve can be opened and closed by manual operation.
