The double eccentric ball valve mainly has the following four characteristics:

1, sealing pair (valve core, seat) -- bimetal, metal spherical ring to achieve hard sealing, fire and explosion protection;

Two, tight seal, valve core and valve seat sealing is spherical line contact, by three-dimensional eccentricity to achieve zero leakage;

The valve core of the sealing pair has a compensation amount. When the valve is used for a long time and the sealing pair is found to be worn, it only needs to loosen the limit bolt on the side of the handwheel and turn a little when it is closed to achieve reliable sealing and prolong the service life.

Four, the pressure sleeve can be screwed off, adjust or replace the seat, the valve can still continue to use, to avoid the current many valve seal failure after the whole set of scrapped disadvantages.

At present, it has been sold well in the coal powder injection in the steel industry, the pulp, mother liquor and aluminum oxide powder transportation in the alumina industry, the hydraulic (or dry) ash removal in the electric power industry, the petrochemical industry, the gas industry and other occasions.
