BD343H insulated butterfly valve, insulated butterfly valve,butterfly valve

The BD343H insulated butterfly valve, also known as the jacketed butterfly valve, is based on the common three-eccentric metal hard-sealed butterfly valve. A metal jacket is welded to the outside of the valve body. On both sides of the valve body of the insulated butterfly valve, there are jacket interfaces, which can be used to insert steam or other superheated gases to prevent the medium from solidifying or crystallizing at normal temperature. The flange of the insulated butterfly valve is one to two specifications larger than that of the ordinary metal hard-sealed butterfly valve. It is mainly used in various systems such as petroleum, chemical engineering, metallurgy, and pharmaceuticals.

Working principle of BD343H insulated butterfly valve:

The valve body and butterfly plate of the BD343H insulated butterfly valve are designed based on the three-dimensional eccentric principle, which idealizes the spatial movement trajectory of the sealing surface. There is no wear or interference between the sealing pairs. In addition, the sealing material is reasonably selected and the valve seat is overlay welded with stl alloy, thus reliably ensuring the sealing performance, high-temperature resistance, wear resistance and corrosion resistance of the entire valve seat.

Product features of BD343H insulated butterfly valve:

It has the advantages of good heat preservation effect, energy saving and consumption reduction, and long service life. Currently, it is a relatively ideal product for sulfur recovery devices.

2. It is designed based on the three-dimensional eccentric principle to achieve the most ideal spatial movement trajectory of the sealing surface.

3. It has a small opening torque, is flexible and convenient, and the three-dimensional eccentric structure enables the butterfly plate to close tighter and tighter, making the sealing performance more reliable.

4. There is no wear or interference between the sealing pairs. Coupled with the reasonable selection of sealing materials and the valve seat surfacing with stl alloy, the sealing performance, high-temperature resistance, wear resistance and corrosion resistance of the entire valve seat are reliably guaranteed.
