Feature:

1.This product has logical structure,reliable seal,excellent performance and design.

2.The seal surface is build-up welding with hard alloy,which is attrition-resistant,corrosion-resistant,has good friction and long life.

3.The stem is quenched and its surface is treated by nitriding treatment,thus it has good corrosion resistant and friction resistant.

4.It has double seal capability,which becomes more reliable.

5.The part material,flange and butt-weld ends dimension selected according to current operating condition and user's requirement to meet various engineer solution projects.

6.We use flexible graphite packing, reliable sealing, light and flexible operation.

7.Simple shape, short structure length and wide application range.
