High Stability Tungsten Carbide And Stainless Steel Stem And Seat Assembly
Detailed Product Description:
Valve stems connects the actuator and disk for positioning the disk in accordance with requirement. Stems are typically forged and connected to the disk by threaded or welded joints. For valve designs requiring stem packing or sealing to prevent leakage, a fine surface finish of the stem in the area of the seal is necessary. Typically, a stem is not considered a pressure boundary part.
The features:
1. Good wear and corrosion resistance
2. Long lifetime
3. Good working performance
4. One stop customized service
5. Standard export package
Main product line:
