Structural Characteristics
Instructions
Fully welded structure
the fully welded structure has light weight and compact structure, eliminating potential leakage channels
Anti-blowing valve stem
upper packing function structure to prevent the valve stem from blowing out, can realize online replacement of filler.
Packing loading and sealing
the packing place adopts the disc spring loading design, and the long-term sealing is more reliable.
Stem seal
use low leakage packing (through API 622 certification), O-ring, emergency fat injection seal at the stem for multiple seals, with more reliable seal.
Double group thrust pad design
it can reduce the valve torque, prevent the valve from stuck after using for a long time, and prolong the service life of the valve.
