The sophisticated U-shaped elastic ring and three eccentric multi-level metal seal mechanism is widely used in medium temperature of ≤ 425 ℃ occasion,in the field of  metallurgy, electric power, petrochemical, as well as drainage and municipal construction etc. to regulate mediation flow and truncate fluid use. The valve is with three-eccentric structure, and its seat and disc plate are made of cast steel and stainless steel, has  good corrosion resistance property, long life-span, and  has  two-way sealing function, the valve producted according to  GB/T13927-92 pressure test standards.

the valve adopts  three eccentric structure, no friction between seat and disc plate, with the function of close tighter when operating many times. |||
The sealing material is made of stainless steel, has the both advantage of metal sealing and plastic sealing, and function well in both low and high temperatures, corrosion resistance, long life-span. |||
The disc sealing surface using cobalt-based alloy welding, has the feature of  wear resistance. |||
The valve has a bi-directional sealing function, can be installed in any direction. |||
 The drive device can be multi-bit (90 ° rotation or 180 °) to install, to convience the users.|||
