Stainless steel check valves are designed and manufactured strictly in accordance with the GB12236 standard. The pin shaft and valve disc are connected using an internal structure, which has excellent performance and more reliable sealing. The product is widely used in pipelines in various working conditions such as petroleum, chemical, pharmaceutical, and power industries.
Features of stainless steel check valves:
1. By adopting excellent hydraulic models and manufacturing processes, the performance and service life of pipeline pumps are greatly improved.
2. Due to the use of mechanical seals made of hard alloy and fluororubber, the performance of pipeline pump operation and the temperature of the conveying medium can be improved.
3. The overflow part of the pipeline pump is made of stainless steel plate stamped and welded, making it suitable for mild corrosive media.
4. The overall structure is compact, small in size, light in weight, low in noise, significantly effective, and easy to maintain.
5. The inlet and outlet of the pipeline pump are located on the same horizontal line as the pump seat, and can be directly used in the pipeline.
6. Using standard motors, users can easily equip motors according to their needs.
7. Intelligent protectors can be equipped according to user needs to protect pumps from dry rotation, phase loss, overload, etc.
