Characteristics:
Reasonable structure,reliable sealing, fine performance.
Sealing face of valve flap and valves 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, anti-corrosion,
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 gasket can be mated
according to practical construction,it is suitable for kinds of pressure,
temperature and medium construction.
