price: 279.00 Dollar US$

Hard seal butterfly valve, wafer type consists of precise J type elastic sealing ring and three eccentric multi-level metal hard seal structure, which is widely used in metallurgy, electric power, petrochemical, and water supply and drainage and other industrial pipe (medium temperature ≤ 400 ℃) for regulating the flow and cutting off the fluid
1. There is almost no wear in the seat and disc and has been a tighter sealing function becasue metal hard seal butterfly valve employs three eccentric seal structure, 2. The sealing ring, made of stainless steel, has double advantages
of elastic seal and metal hard seal. Whether in low temperature or in high temperature, it has corrosion resistance, excellent sealing performance, long service life, etc.
3.Large size disc uses lattice structure, with high strength, large flow area and small flow resistance.
4. Metal hard seal butterfly valve has a two-way sealing function.It is neither subject to the flow direction of medium nor affected by the spatial location when installed. It can be installed in any direction.
5. The actuating device can be installed with multi-station (rotated 90 ° or 180 °), ease for the users
