Characteristics:
Reasonable structure,reliable sealing,fine performance.
Sealing face of valve flap and valve base adopts iron base alloy or
Stellite cobalt base hard alloy for bead welding to form,it has good
performance such as anti-abrasion,anti-high temperature, anticorrosion,
and even long service life.
Adopt kinds of piping flange standard and sealing face type of
flanges, satisfy the project demand and user' s requirement.
Variety of valve body material is complete,the pad can be mated
according to practical construction,it is suitable for kinds of pressure,
temperature and medium construction.
Pin and valve flap adopts build-in structure,it hasn't existed outside
leakage point,it is more reliable during using.
