Quick disconnect fittings (abbreviated as “QDCs” or “QDs”) are used to provide fast and easy connection and disconnection of fluid lines. These fittings are also known as quick connects or quick release couplings. They often are used to replace fitting connections which require tools to assemble and disassemble.
Directional control valves are used in pneumatic systems to direct or stop the flow of compressed air or oil to their appliances. They are probably the most used elements in pneumatic systems and can be used for example to actuate a cylinder, a larger industrial valve, or air tools. The valves can have two or more ports and fulfil various circuit functions. The function and behaviour of the valve can be indicated by a symbol. The symbol however doesn't explain the construction of the valve. Directional control valves can be actuated by different means, such as manual actuation or solenoid actuation. This article focuses on the different directional solenoid valves for pneumatic systems.
The Push - In One Touch Fittings series pneumatic piping joints excelling in quick fitting, accurate jointing and compact design are suited to the pneumatic systems necessary for automation and labor saving. The tube can be fitted and detached easily, so that workability is remarkably improved. Pressure loss is reduced. A large volume of compressed air can be fed with least pressure loss without air leak. Moreover the joints have a compact design. Thus the joints will satisfy strict user's demands.
