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,corrosion-resistant,has good friction resistant
and long life.
3.The stem is 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 chearer.
6.The part material,flange and butt weld end dimension may be
selected accordng to current operating condition and
users'requirement,so that meet the requirements of various
engineering.
