Product Introduction
The Flange Connection Globe Valve is suitable for pipeline of petroleum, chemistry,medicine,chemical fertilize,power industry etc. and so on with norminal pressure PN1.6-4.0MPa, working Temperature -29~425(C). The suitable medium are water, oil, steam,acid medium and so on.It can be mated driving mechanisms like manual, gear box, pneumatic, electric operator.
Product Features
1.Reasonable st ructure, rel iable seal ing, f ine performance, fine look.
2.Sealing face of valve flap and valve base adopts iron base alloy or Stellite cobalt base alloy with bead welding to form, it has good performance such as ant i-abrasion,anti-high temperature,anti-corrosion,and even long service life.
3.Stem treated by tempering and cementing has good performance such as anti-corrosion,scraping resistance.
4.Adopt kinds of piping flange standard and sealing face type of flanges,satisfy the project demand and user' s requirement.
5.Variety of valve body materials can be mated according to practical project,it is suitable for kinds of pressure,temperature and medium construction.
6.Easy maintenance, replacing packing can be changed easily and quickly under operating and no interference with the system.
