How to choose a fast joint

1, the type of fluid, temperature ( select suitable for the type of fluid, temperature of the body material and sealing material quick connector) According to rotating joints the fluid, is suitable for the body material. Sealing material is different. For example, quick joint is air. Recommend the steel, water is made of brass or stainless steel.

2, the pressure of the liquid ( select suitable for fluid pressure resistance of quick connector) The pressure of the fluid is selected fast joint key. Use of hydraulic quick connector is 5.0Mpa (51kgf/cm² -68.6Mpa (700kgf/cm&sup2);) is formed between the series, corresponding to the withstand voltage characteristic, fast joint structure is different.

3, an automatic switch valve structure ( select suitable piping purpose valve structure quick connector) The valve structure, two rotary union switch type, one-way switch type and two open. Due to the separation of two switch type except outside, with fluid from the pipe flow. So please note.

4, quick joints use environment ( select suitable environment structure, material of the quick connector) Combined use of environmental humidity, dust, and easy corrosion environment, to consider the selected fast joint type, body material, sealing material.

5, the installation shape, size ( please in determining the final shape, size of products of order) Please identify the fiber optic rotary joint fast models and materials, and specify the corresponding to the characteristics of the shape and size of the piping assembly. Please note that the size is associated with fluid flow.
