How to select quick coupling

Knowledge of selecting quick coupling

1. fluid types, temperature (please select the type, suitable for fluid temperature of the material and sealing material of quick coupling) According to the fluid, suitable for the ontology of material, the seal material is different. For example, quick coupling is the air. Recommend made of steel.If quick coupling is the water ,you can choose brass or made of stainless steel.
2. the liquid pressure (please select suitable for fluid pressure these properties of quick coupling) Fluid pressure is also the key to selected quick connectors. With oil pressure of quick coupling is 5.0 Mpa (51 KGF/cm 2)-68.6 Mpa (700 KGF/cm 2) formed between the series, corresponding to compression characteristic, the structure of the quick couplings are also different.
3. automatic switch valve structure (please select suitable for piping USES of the structure of the valve quickly joint) For the structure of the valve, have two way switch type, one-way switch type and the two way open. As in the separation in two road except outside switch mode, fluid with out from inside. So please note.
4. quick coupling the use environment of (please select suitable for use of the environment of the structure, materials of rapid joint) Using a combination of environment humidity conditions, the condition of the dust, and easy to use, the corrosion environment, to consider the selected the kinds of quick coupling, ontology material qualitative, seal material.
5. the shape and size of installation (please in determining the final shape, size order products after) Please be sure to quick coupling type and material, and appoint pipe characteristics corresponding to the assembly of shape and feet + inch. Please note that size is connected with the fluid flow
