Product Name: worm gear transmission wafer butterfly valve
Product description:
Product use:
I company for clip-on butterfly valve product is used in the petroleum, chemical, metallurgy, electric power, food, pharmaceutical, water supply and drainage, gas delivery pipes of different media such as for regulating the flow of fluid, cutting off or switching on the best device.
The choice of different materials, which were applied in the petroleum, natural gas, water, sewage, water, air, steam, gas, combustible gas, corrosive medium, oil and food and other media, the highest working temperature can reach 650 ℃, maximum pressure up to 3.0MPa
Product features:
The butterfly is my company independent research and development of new type butterfly valve products, with three eccentric metal sealing structure, no mechanical abrasion, can achieve zero leakage, good sealing function.
Butterfly valve sealing surface of the valve plate is spherical (material 304 or 316 stainless steel ) with the elastic ring seat in a circular arc (material 304 or 316 stainless steel ) contact sealing effect, this is the best line sealing effect, so that the sealing surface friction is reduced to the minimum, the shaft torque force came to the small. Because the elastic ring seat of the special structure, the butterfly valve has good anti " explosive decompression " effect, the other valve plate sealing surface and an elastic ring seat surface after special hardening, hardness above HRC60, so that the service life of the butterfly valve and corrosion resistance are fully get promotion. This butterfly valve according to the respective material configuration, high temperature from -39℃-- 650 ℃, pressure 3.0MPa. specification is DN50-DN1200.
Connection: clamping type drive mode: manual, worm gear drive, electric, pneumatic
