Flanged Electric Actuated Butterfly Valve is suitable for industries with temperature below 150℃ and nominal pressure less than 1.6 MPa. It is suitable for drainage, sewage, food, heating, gas, ship, water and electricity, metallurgy, energy system and light textile industry especially suitable for two-way seal and valve body easy to rust occasions, as the regulation of flow and intercepting medium.
Metal-sealed valves generally have a longer life than resilient-sealed valves, but are difficult to completely seal. The metal seal can adapt to the higher working temperature, while the elastic seal has the defect limited by the temperature.
The Flange Electric Actuated Butterfly Valve is usually composed of angle stroke electric actuator and flange butterfly valve through mechanical connection, after installation and debugging.
The disc of the electric flanged butterfly valve is installed in the diameter direction of the pipe. In the flange electric actuated butterfly valve body cylindrical channel, disc around the axis of rotation, rotation angle of 0 ~ 90, rotation to 90, the valve is in full open state.
Flange electric actuated butterfly valve with simple structure, small size, light weight, only a few parts. The valve can be opened and closed quickly by rotating only 90°. The operation is simple and the valve has good flow control characteristics. When the flange butterfly valve is in full open position, the disc thickness is the only resistance when the medium flows through the valve body, so the pressure drop through the valve is very small, so it has better flow control characteristics. Butterfly valve has elastic seal and metal seal two types. Elastic seal valve, the seal ring can be embedded in the body or attached to the periphery of the disc.
Metal-sealed valves generally have a longer life than resilient-sealed valves, but are difficult to completely seal. The metal seal can adapt to the higher working temperature, while the elastic seal has the defect limited by the temperature.
There are two kinds of electric flanged butterfly valves: wafer butterfly valve and flanged butterfly valve. Clip-on butterfly valve is a double-headed Bolt connecting the valve between the two pipe flange, flange-type butterfly valve is a valve with flange, with bolts on the two ends of the valve flange in the pipeline.
In the fully open position, the disc thickness is the only resistance to the flow of media through the valve body, so the pressure drop through the valve is very small, so it has good flow control characteristics. Electric flanged butterfly valve has elastic seal and metal seal two types. Elastic seal valve, the seal ring can be embedded in the body or attached to the periphery of the disc.
Metal-sealed valves generally have a longer life than resilient-sealed valves, but are difficult to completely seal. The metal seal can adapt to the higher working temperature, while the elastic seal has the defect limited by the temperature.
The flanged butterfly valve has the following 9 advantages:
1. Small and lightweight, easy to disassemble and repair, and can be installed in any location.
2. The structure is simple, compact, operation Torque is small, 90 turn on quickly.
3. Flow characteristics to a straight line, good regulation performance.
4. The connection of the butterfly plate and the valve stem adopts the pin-free structure, which overcomes the possible internal leakage point.
5. The outer circle of the butterfly plate adopts spherical shape, which improves the sealing performance and prolongs the service life of the valve, and keeps zero leakage even more than 50,000 times of opening and closing with pressure.
6. Seals can be replaced, and reliable sealing to two-way seal.
7. Butterfly plate can be based on user requirements spray coating, such as nylon or PTFE class.
8. The valve can be designed as flange connection and clamp connection.
9. The drive mode can be manual, electric or pneumatic.
