Characteristics:
Reasonable st ructure, rel iable seal ing, f ine performance,
fine look.
Sealing face of valve flap and valve base adopts iron base
alloy or Stellite cobalt base alloy with bead welding to form,
i t has good performance such as ant i-abrasion,anti-high
temperature,anti-corrosion,and even long service life.
Stem treated by tempering and cementing has good performance
such as anti-corrosion,scraping resistance.
Adopt kinds of piping flange standard and sealing face type
of flanges,satisfy the project demand and user' s requirement.
Variety of valve body materials can be mated according to
practical project,it is suitable for kinds of pressure,temperature
and medium construction.
