D943H electric butterfly valve for gas

First, electric gas butterfly valve structure and performance introduction
This product is composed of valve body, control plate, sealing ring, transmission mechanism and other main components. Its structure adopts three-dimensional eccentric principle design, elastic seal and hard and soft multi-layer seal compatible processing technology, so that the butterfly valve in operation, reduce its torque force, to achieve labor saving, energy saving functions. Thus ensuring overall corrosion resistance. High temperature resistance. , the reliability of anti-degradation.

Second, the main performance characteristics of electric gas butterfly valve are:
1. Structure, small and light, flexible operation, labor-saving, convenient;
2. Reliable sealing, can achieve gas seal without leakage;
3. The flow characteristics tend to be linearly regulated.
4. The three-eccentric principle is adopted to make the sealing surface approximate zero loss and extend the service life of the valve.
5. Wide range of applications. Such as: can be used for water, steam, oil, air, gas and other media.
6. Applicable to different temperatures and pressure levels below 6.4MPa, corrosion resistance and other medium pipelines.
