1. type, temperature of fluid (please select suitable type of fluid and the temperature of the camlock coupling made of the body material and seal material) According to fluid, suitable body materials and seal materials are different. For example, the camlock coupling is air hose coupling, recommend steel system. Water kind while choose brass or stainless steel. 2. fluid pressure (see the select pressure for fluid pressure in the performance of the camlock coupling) The fluid pressure is also key to the selecting camlock coupling. Hydraulic camlock coupling is used to 5.0Mpa (51kgf/cm ²)-68.6Mpa (700kgf/cm ²) formed between the series, the corresponding features on the pressure, rapid construction of joints are different. 3. the structure of automatically switches valve (Please select camlock coupling for appropriate use of valves piping constructed) For the construction of the valve, there are two-way switch type, one-way switching and two-way open. Since the separation, inter-type other than the two-way switch, there is outflow of fluid from inside the piping. Therefore, please pay attention. 4. use environment of camlock coupling (please select camlock coupling for suitable environment, construction and materials) Combination of environmental conditions, humidity, dust conditions, and easy to use environment corrosion, to consider the selection of quick joint type, body material, seal material. 5. the shape and size of the installation (please after determining the final shape and size to order products) Make sure camlock coupling type and material, and specify the corresponding piping assembly characteristics of the shape and size. Please note that size is connected with the fluid flow.
