By adopting a special packing structure, it can meet the requirements of leakage levels below 100ppm, while reducing the friction on the valve stem by about 20%.
◆Valve structural characteristics
1、Adopting a threshold rod anti flying structure can ensure that the valve stem does not fly out and cause accidental injury.
2、The valve seat adopts waveform spring or cylindrical spring and double scraper structure, which can clean the spherical surface and ensure sealing.
3、Adopting a dual sealing structure can ensure that the medium does not come into contact with the spring, ensuring valve sealing.
4、The sealing performance of the soft seal valve seat is more stable and reliable.
5、Design a sewage blowing structure to clean the valve and prevent it from getting stuck.
6、Meets the requirements of API607 standard and has fire and anti-static functions.
