The metal hard sealing abrasion-resistance ball valve, a distinctive product researched and developed by our company, is applicable for tough working conditions like high impurity, viscosity, temperature and pressure as well as strong corrosion. It adopts reasonable, applicable and high-quality materials, brand-new design concept, advanced production and processing procedures, and whole-process quality control to make every valve satisfied by customers. It has been widely applied In such industries as petrochemical(PE, PP, He-catalytic cracking, cracking, ethylene, synthetic resin, silicon powder, etc. ); Water drainage of main steam pipeline in power plant; Coal powder, deslagging and desulfuration of steel mill; High-pressure melting and slurry filtering system in alumina plant; And coking coal to oil transfer.

Design Concept
1 Our company adopts different valve designs in accordance with different working conditions:
The valve seat and ball sealing surface adopt the metal to metal seal while its ball and seat adopt the special hardening treatment to ensure reliable seal, resistance to high temperature, abrasion and corrosion and a long service life. Its ball and seat are provided with good cutting and self-cleaning functions, applicable for the control over media containing grains and fibers.

2 The seat adopts the plate or compression spring load so that it can avoid the jamming between its ball and seat caused by thermal expansion and cold shrinkage, especially in a state or high or low temperature, in which the flexible seat structure with the automatic compensation function is adopted so that the amount of deformation of its ball and seat can be absorbed by the plate or compression spring, thus it can be opened or closed freely in that state with the reliable seal.

3 Its seat seal can adopt the O-ring, graphite gasket or pretightening graphite seal in accordance with working conditions and temperature; These structure types can be adopted reasonably in accordance with actual working conditions to get a satisfactory result. Our hard sealing fixed ball valve adopts the pre-ball seal structure generally with double block and bleed functions (DBB structure). Generally the Floating Ball Valve adopts the post-ball seat seal structure, which is a kind of one-way seal structure; The floating double-way seal structure can also be adopted in case of special requirements by users.

4 The stem seal of hard sealing ball valve adopts the flexible graphite packing while the flange adopts the flexible graphite with stainless steel wire or the metal twisted graphite gasket, thus boasting the functions of intrinsic safety for fire (conforming to AP1607) and electrostatic prevention (conforming to API607). It adopts the bottom-mounting and blowout-proof structure so as to avoid the blowout of stem caused by the valve misoperation.
