product features
1. the selection of materials is exquisite, in line with relevant domestic and foreign standards, and the overall quality of materials is high.
2. it meets the requirements of domestic and foreign standards, with reliable sealing, excellent performance and beautiful appearance.
3. the matching of sealing pairs is reasonable. the sealing surfaces of the gate and valve seat are made of stellite cobalt-based hard alloys with different hardnesses. the sealing is reliable, high hardness, wear resistance, high temperature resistance, corrosion resistance, good scratch resistance and long life.
4. the valve stem has good corrosion resistance, scratch resistance and wear resistance after quenching and tempering and surface nitriding treatment.
5. the wedge-type elastic ram structure is adopted, the medium and large diameters are provided with thrust bearings, the friction force is small, and it is equipped with an impact manual, which can be opened and closed easily.
6. various piping flange standards and flange sealing surface forms can be used to meet various engineering needs and user requirements.
