D973H/Y Electric wafer flange hard seal butterfly valve product details

D973H/Y Electric wafer flange hard seal butterfly valve product description

D973H/Y Electric wafer flange hard seal butterfly valve produced and sold by Baigang valve group with a "U" stainless steel seal, the precision of the elastic ring and polished disc three-dimensional eccentric contact. It solves the defect that the traditional eccentric butterfly valve is still in sliding contact friction at the moment when the opening and closing is 0 ° ~ 10 °, so that the sealing surface of the butterfly plate can be separated at the moment of opening and the effect of closing the contact is sealed, thus prolonging the service life and sealing performance Good purpose. Therefore, it is widely applied to the pipeline of metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas and water supply and drainage corrosive media with medium temperature ≤550 ℃. It is the best device to regulate the flow and cut off the fluid.

D973H/Y Electric wafer flange hard seal butterfly valve product features

1, the butterfly valve structure is simple, compact, light weight, easy to install and disassemble, easy maintenance;
2, the butterfly valve with stainless steel "U" ring, with a certain flexibility in both high temperature and low temperature, All have excellent sealing;
3, the three-dimensional eccentricity of the butterfly valve, after rigorous calculations, "U" type ring and disc almost no friction, long service life
4, The sealing surface of the plate is cladded with cobalt-based cemented carbide, and the sealing surface is resistant to abrasion and long service life.
5, The butterfly valve has a unique structure and the "switch" can be completed by only rotating the valve stem by 90 °. Operation flexibility, convenience, effort, not affected by the level of media pressure, sealing performance and reliable;
6, high temperature, low temperature, corrosion resistance.
