Product Overview: D941X Electric Soft Seal Flange Butterfly Valve

D941X electric soft seal flange butterfly valve as a new generation of speed control type butterfly valve, this valve from the design idea to change the traditional mode of relying on mechanical speed to complete the butterfly switching speed change, according to the butterfly plate action characteristics of different positions, from the electric drive control on the new design. The electric soft seal flange butterfly valve adopts to change the frequency of the input current of the electric device, and then adjusts the rotation speed and output torque of the electric device, in order to achieve the control of the butterfly plate opening and closing speed, and to realize the purpose of the butterfly plate fast closing, slow closing two-stage closure or slow opening, fast opening two-stage opening. It has the same function with liquid-controlled butterfly valve.

Product use

Electric soft seal flange butterfly valve is suitable for the medium of water, seawater pipeline pump outlet position, as a closed-circuit valve with the characteristics of the check valve, to avoid and reduce the backflow of the medium in the pipeline system and the impact of water hammer, to protect the pipeline. For power plants, water plants and other very reliable power supply is particularly suitable for the occasion.

Product features

1. Electric opening and closing, with arbitrary adjustment, check and cut-off function. Convenient operation, safe and reliable.

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

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

4. when installed at the pump outlet, this butterfly valve has the common functions of check ah and gate valve at the same time, so it can be a valve instead of two valves, saving installation space and saving the cost of pipeline network.

5. Small flow resistance. When the valve is fully open, the flow resistance coefficient is not more than 0.3, so it can save energy and reduce the running cost of pipeline.

6. when an accident or power failure occurs, the butterfly valve can be manually operated to control the opening and closing.
