German Patent Branch standard pull-wedge gate valve block structure, really protect water piping systems 100% unchanged, to solve the industry's internal use of shut-off valve, and the quantity of water pipeline system greatly reduced to less than 25% seriously can not guarantee that serious design flaws lose water. Greatly improved the water through the pipeline to ensure a stable water pressure.
Gate-type structural features all-copper contacts, instead of the normal valve plastic gasket to avoid water leakage caused by defects in plastic aging rotten, to maximize the elimination of leakage risk.
For ergonomic handwheel design, feel comfortable;
For the PTFE washer, not afraid of high temperature, the use of safety;
For ISO228 100% GB aperture design, water transport, avoid water closure defects;
For the closed gate patent, mechanical seal, anti aging;
