Three eccentric multi-level seal butterfly valve profile
ã€Product Overview】 Three eccentric hard sealing butterfly valve based on advanced foreign technology, the use of sophisticated J-shaped elastic ring and three eccentric multi-layer metal hard seal structure, is widely used in the medium temperature ≤ 425 ℃ of governance gold, electricity, oil Chemical, and plumbing and municipal construction and other industrial pipelines, for regulating the flow and breaking the fluid to use. The valve adopts three eccentric structure, the valve seat and the disc sealing surface are made of different hardness and stainless steel, has good corrosion resistance, long service life, the valve Jun mail two-way sealing function, the product complies with national GB / T13927-92 valve pressure Test Standard. ã€Features】 The valve adopts three eccentric sealing structure, the valve seat and disc almost no wear, with the more the more tight sealing function. Sealing ring made of stainless steel, metal seal with a double seal and flexible advantages, both in the case of low temperature and high temperature, have excellent sealing performance, with corrosion-resistant, long service life and so on. The sealing surface of the disc is made of cobalt-based hardfacing alloy, the wearing surface of the sealing surface is wear-resistant and the service life is long. The large-sized disc adopts the structure of the brackets, which has the advantages of high intensity, large flow area and small flow resistance. The valve has a two-way sealing function, the installation is not subject to restrictions on the flow of media, but also space location, can be installed in any direction. Drive can be multi-station (rotated 90 ° or 180 °) installation, user-friendly. ã€Main technical parameters】 Nominal through DN (mm) 50 ~ 2000 Nominal pharmacology PN (MPa) 0.6 1.0 1.6 2.5 Sealing test (MPa) 0.66 1.1 1.76 2.75 Strength test (MPa) 0.9 1.5 2.4 3.75 Applicable temperature Carbon steel: -29 ℃ ~ 425 ℃ Stainless steel: -40 ℃ ~ 650 ℃ Applicable medium Water, air, natural gas, oil and weak corrosive fluid Leakage rate Complies with GB / T13927-92 standard Drive Worm drive, electric, pneumatic, hydraulic More key Word search: butterfly valve
