Remote Control Electric 1200mm Ductile Iron Butterfly Valve

Remote Control Electric 1200mm Ductile Iron Butterfly Valve

The electric butterfly valve controls the switch through the power signal. The product can be used as shut-off valve, control valve and check valve of pipeline system. With manual control device, in case of power failure, it can be operated manually temporarily without affecting the use.

The electric butterfly valve is suitable for the occasion of flow regulation. Since the pressure loss of butterfly valve in the pipeline is relatively large, which is about three times of that of gate valve, the influence of pressure loss on pipeline system should be fully considered when selecting butterfly valve, and the firmness of butterfly plate bearing pipeline medium pressure when closing should also be considered. In addition, the working temperature limit of resilient seat material at high temperature must be considered. The structure length and overall height of butterfly valve is small, the opening and closing speed is fast, and it has good fluid control characteristics. The structure principle of butterfly valve is suitable for making large diameter valve. When butterfly valve is required to be used to control flow, it is important to select the size and type of butterfly valve correctly to make it work properly and effectively.

1. Small and light, easy to disassemble and repair, and can be installed in any position.

2. The structure is simple and compact, the operation torque is small, and the 90 ° rotary opening is quick.

3. The flow characteristics tend to be straight line and the regulation performance is good.

4. The connection between the butterfly plate and the valve stem adopts the structure without pin, which overcomes the possible internal leakage point.

5. The outer circle of butterfly plate adopts spherical shape, which improves the sealing performance and prolongs the service life of the valve, and keeps zero leakage after more than 50000 times of opening and closing under pressure.

6. The sealing element can be replaced, and the sealing is reliable to achieve bidirectional sealing.

7. Butterfly plate can be sprayed with coating according to user's requirements, such as nylon or PTFE.

8. The valve can be designed as flange connection and clamp connection
