Axial flow check valve is a high-performance check valve designed in accordance with API 6D and ASME B16.34. It is widely used in pipeline systems to prevent liquid backflow hazards and protect mechanical equipment. It not only has the functional characteristics of general check valves, but also has superior features such as reducing water hammer hazards, noise, pressure drop, and rapid response. According to the different working temperatures and pressure differentials, Nujing can provide corresponding solutions and professional technical services.
