Product Description

The main parts of electric BW metal seated butterfly valve include valve body, butterfly plate, sealing ring, transmission mechanism, etc. The structural design adopts two-dimensional or three-dimensional eccentric principle, and applies new processing technology compatible with elastic seal or soft and hard multi-layer seal, which helps to reduce the torque in valve operation, achieve the purpose of saving labor and effort, and does not affect the overall corrosion resistance, high temperature resistance, and wear resistance.

This butterfly valve can be used in different industrial fields and has received praise and recognition from many factory customers. We are well aware that preferential prices are inseparable from mature upstream and downstream supply chain systems and excellent processing equipment. This is also what we have always attached great importance to. We will increase investment every year to keep Waits valves reliable quality and preferential prices.

Performance Features

1. The electric BW metal seated butterfly valve is more lightweight and flexible in structural design, saving effort and being convenient.

2. The sealing performance is reliable and meets various standards.

3. The valve has adjustable function and good flow characteristics.

4. The eccentric principle is adopted, the wear of the sealing surface is close to zero, and the service life is longer;

5. It can be used for a variety of different media, such as water, steam, oil, air, gas, etc.; it can also be used for pipelines of various working conditions such as different temperatures, grades, corrosion, etc.

6. The valve body and the valve seat are connecting parts, and the sealing surface layer of the valve seat is welded with heat-resistant and corrosion-resistant alloy materials.

7. The center line of the shaft deviates from the center line of the sealing surface, the center line of the shaft deviates slightly from the center line of the pipeline, and the center line of the valve body sealing surface (oblique cone) is at an angle with the center line of the pipeline. The above three are three eccentric designs.

8. There are multiple layers of sealing rings fixed on the valve plate, which are easy to operate, no friction when opening and closing, and the torque of the transmission mechanism increases when closing, compensating the seal.

9. The multi-layer sealing ring adopts soft and hard laminated metal sheets, which has dual advantages.
