The packing of this valve adopts a composite structure of upper and lower gland rings, which is characterized by excellent stability. There will be no leakage fluctuations even under alternating hot and cold conditions. The usage cost is less than one-fourth of that of European and American brands. Therefore, if you specify the use of our low-leakage packing, it will significantly reduce costs while ensuring reliable sealing performance. We also provide professional technical guidance for the installation of the packing and the overall machining process.
