【Product Introduction:

Bi-directional triple offset butterfly valve no matter which direction the medium comes from, the two-way sealed three eccentric butterfly valve sealing butterfly valve can be sealed.

The butterfly valve uses a high-performance composite sealing pair, or a surfacing alloy steel sealing pair, zero leakage, and long life. Bidirectional Triple Offset Butterfly Valve's sealing surface materials are alloy steel, polylactide, rubber, and PTFE seals; the connection type is flanged and wafer type. 

The butterfly valve is suitable for which require two-way sealing, frequent opening and closing, high reliability, pure pipelines and important pipelines in petrochemical, electric power, alloy, transportation, large-scale construction and other fields.

Product Features

1. Bidirectional Triple Offset Butterfly Valve solves the problem of two-way sealing of metal hard seal butterfly valves with three eccentric structures.

2. The butterfly plate adopts a truss type structure with good rigidity and small deformation.

3. The sealing surface of the valve plate and the valve seat is an oblique conical structure, and the temperature-resistant and corrosion-resistant alloy material is deposited on the inclined conical surface of the valve plate.

4. It adopts soft T-shaped multi-layer stainless steel sheets on both sides to form a sealing ring. It has zero leakage sealing performance under low temperature and high temperature conditions.

Nowadays, the two-way sealing butterfly valve produced by many manufacturers adopts the same structural design as the ordinary one-way sealing butterfly valve, only increases the diameter of the valve stem and increases the thickness of the sealing ring. Although this structure can be sealed, it is limited to small diameter valves, and the flow rate in the pipeline is small.
