2)The sealing face of gate and seat is overlaid-welding with carbide alloy for erosion and corrosion resistance;
3)The imported lip-type composite gate and seat, stem seal provide reliable sealing, safety and minimize operational torque;
4)Back seal structure of the stem allows the replacement of the packing under the working pressure;
5)Valve structure include two kinds:rising stem ad non-rising stem, with visible sign for opening and closing the valve;
6)Gate structure:Integral or split;
7)The seat is classified into floating and fixed structure;
8)Driving model: Manual, Hydraulic and gear drive;

Spring energized seal and metal O Ring offer the highest sealing performance in the harshest industrial environments. These seals feature outstanding chemical compatibility, low friction, long service life and durability in low temperature or cryogenic applications. Typical uses include compressed gas waterless fracking seals, LPG, and liquid nitrogen, as well as rotary, reciprocating, and oscillatory motions. Spring energized seals and metal o-rings deliver the ultimate sealing performance in a wide range of demanding environments.
