1. It has stable sealing performance under high temperature and high pressure conditions. Its special sealing system can guarantee high sealing performance from ultra-low temperature to ultra-high temperature.

2, three-dimensional eccentric sealing system plus the optimized design of the valve, the valve opening resistance is small. The sealing surface of the butterfly plate is an upwardly convex cone. When opening, the points on the circumferential surface of the butterfly plate are simultaneously separated from the sealing ring, and the solid matter is not easy. Stacking on the sealing surface. The valve closing process is completed by the elastic compression of the sealing ring.

3. There is no phase-card phenomenon between the butterfly plate and the sealing ring.

4. The sealing performance of the valve is not affected by temperature changes.

5. The stem diameter of the valve stem is sealed by graphite. The above-mentioned guarantee ensures zero leakage. The metal seal is zero leakage before, during and after the fire, so it is an essential fire safety type.

(1) The double eccentric structure is adopted, and the sealing function is tighter and tighter, and the sealing performance is reliable.

(2) The sealing accessory material is matched with stainless steel and nitrile oil resistant rubber, and has a long service life.

(3) The rubber sealing ring can be located on the valve body or on the butterfly board, and can be applied to different media for users to choose.

(4) The butterfly plate adopts a frame structure with high strength, large flow area and small flow resistance.

(5) The overall baking varnish can effectively prevent rust and can be used for different media as long as the sealing seat sealing material is replaced.

(6) The valve has a two-way sealing function, which is not controlled by the flow direction of the medium during installation, and is not affected by the spatial position. Can be installed in any direction.

(7) It has small volume, light weight, reliable performance, simple matching and large circulation capacity, especially suitable for medium is clean liquid and gas.

It is widely used in industrial process automatic control systems for food, environmental protection, light industry, petroleum, chemical, water treatment, municipal engineering, papermaking, electric power, water treatment and other industries. Electric butterfly valves are suitable for the HVAC and refrigeration industries, as well as for industrial applications, general service areas and water treatment.
