subject: The use of quick couplings and pneumatic fittings [print this page] Pneumatic fittings series consists of: air pressure generating device,the pneumatic fittings air compressor. Pneumatic actuators. Pneumatic control components used to control the working fluid pressure, flow and flow way for the implementation of the necessary components to complete the movement characteristics of components, such as pressure, flow and directional control valves and various logic devices, etc.. Sensors and conversion devices will be charged into a pressure parameter detected and the signal of Qigong and the gas sensor signal and the electro-hydraulic components such as signal conversion with each other. Pneumatic accessories, including clean air source, component lubrication, component connections and components such as silencers.
