Product structural features
Bellows globe valves are ideal for nominal pressure PN1.6~4.0 Mpa,working temperature-20℃~350℃of petroleum,chemical,pharma-
ceutical,chemical fertilizer,the electric power industry under various working conditions such as pipelines,cut off or connect piping medium.
1、This product has logical structure,reliable seal,excellent performance and nice design.
2、The seal surface is build-up welding with Co hard alloy,which is attrition-resistant,corrosionresistant,has good friction resistant and long life.
3、The stem quenched and tempered,and its surface is treated by nitriding treatment,thus it has good corrosion resistant and friction resistant.
4、It has double seal capability,thus is more reliable.
5、The stem may show the position of lift,thus it is clearer.
6、The part material,flange and butt weld and dimension may be selected according to current operating condition and Users'requiremnt,so thatmeeting the requirements of various engineering.
