Level metal hard seal structure, make the seat and disc plate sealing surface adopts different hardness and stainless steel, has a good corrosion resistance, the use of life

Life is long, this valve two-way sealed function. Wafer multi-level hard seal butterfly valve is widely used in medium temperature 425 °C or less of metallurgy, electric power, oil change

Work, and water supply and drainage and municipal construction, and other industrial piping, to adjust flow and load flow body use.

D373H - 16 c to clamp hard seal butterfly valve performance features:

1, body chooses the public sector of the carbon steel or stainless steel production, with metal hard seal and elastic sealed double advantages, no matter in low temperature and high temperature affection

Condition, all with excellent seal performance, and has corrosion resistance, long life and other characteristics.

2, the three eccentric seal structure, the seat and disc almost no wear, with the view of the tight seal function.

3, dish plate facing the overlaying cobalt base carbide, sealing surface wear resistance and long service life.

4, large size butterfly plate the supporting structure structure, high strength, flow area is large, small flow resistance.

5, this valve has two-way sealed function, can transfer installation are not affected by the flow direction of medium restrictions, not affected by the influence of the space position, can be in any direction Ann loading.
