Multi-layer hard sealed butterfly valve series products, long life, energy saving type butterfly valve. A tɛ̈n tɔ̈u në three-dimensional centering principle, valve seat tɔ̈u në multi-layer structure ye kɔc cɔl hard soft sealing. Kä ye looi aye looi në valve body, butterfly plate, multi-level valve seat, valve rod, drive mechanism, etc. O kɔrɔ la, a tɛ̈n luɔ̈ɔ̈i në metallurgy, electricity, petroleum, chemical, air, gas, combustible gases ku jɔl ya pipi ye kɔnɔ̈ɔ̈ŋ ye kɔnɔ̈ɔ̈ŋ ye kɔnɔ̈ɔ̈ŋ ye kɔnɔ̈ɔ̈ŋ ye kɔ
