Performance

  • This product has logical structure, reliable seal, excellent performance and nice design.
  • The seal surface is build-up welding with Co hard alloy, which is attrition-resistant, corrosion-resistant, has good friction resistant and long life.
  • The stem is quenched and tempered, and its surface is treated by nitriding treatment, thus it has good corrosion resistant and friction resistant.
  • It has double seal capability, thus is more reliable.
  • The stem may show the position of lift, thus it is clearer.
  • The part material, flange and butt weld end dimension may be selected according to current operating condition and users' requirement, so that meet the requirements of various engineering.
