1. Wafer Type Butterfly Valves
Wafer Type Butterfly Valve's butterfly plate is installed in the diameter direction of the pipeline, and the valve is fully open.
Wafer Type Butterfly Valve has simple structure, small volume and light weight. Butterfly valve has elastic seal and metal seal two sealing forms. Resilient sealing valve, the seal ring can be set in the valve body or attached to the butterfly plate around.
2. Flanged butterfly valve
Flanged butterfly valve is a vertical plate structure, the valve stem is a monolithic metal hard seal valve sealing ring for the flexible graphite plate and stainless steel plate composite structure, mounted on the valve body, butterfly plate sealing surface surfaces surfacing stainless steel. The sealing ring of the soft seal valve is made of nitrile rubber, which is installed on the butterfly plate.
3. Welded butterfly valve
Welded butterfly valve is a non-closed butterfly valve, widely used in building materials, metallurgy, mining, electric power and other production processes in the medium temperature ≤ 300 ℃, the nominal pressure of 0.1Mpa pipeline, used to connect, open and close or adjust the amount of media.
4. Screw Butterfly Valve
Button butterfly valve refers to the valve body with internal or external threads, and pipeline threads connected to the butterfly valve.
5. Clamp butterfly valve
Clamp butterfly valve to be installed on the valve stem reducer, so that the butterfly plate stops in any position, to improve the operating performance of the valve, clamp butterfly valve nominal diameter is large, the valve body is made of carbon steel, its cost is higher, the sealing ring of the valve plate using a metal ring instead of a rubber ring.
