Performance

This product has logical structure, reliable seal, excellent performance and nice design.
The seal surface is build-up welding with Co hard alloy, which is attrition-resistant, corrosion-resistant, has good friction resistant and long life.
The stem is quenched and tempered, and its surface is treated by nitriding treatment, thus it has good corrosion resistant and friction resistant.
It has double seal capability, thus is more reliable.
The stem may show the position of lift, thus it is clearer.
Small flowing resistance and low pressure drop.
The part material, flange and butt weld end dimension may be selected according to current operating condition and users' requirement, so that meet the requirements of various engineering.
