Therefore achieve satisfied the needs of customers, different check usage and application method is different also, for everybody below a: gap type check valve gap type check Industrial Valves suitable for easy to breed hair not boiled water hammer on the pipeline, gap can be better to eliminate medium backflow when the occurrence of water hammer, it is also commonly used on low pressure pipe at room temperature, the practical in conduit road, never the same general medium temperature in - things 12 - - Between 120 ℃, pressure & lt; 1. 。 【 Q 】 Diaphragm type check valves and ball check valves difference [ A 】 According to the check valve shall confirm the relevant provisions of the corresponding size, valve supply business will supply the size of the selected numerical data, so you can find under a given flow valve the paper thickness of the valve size. Therefore achieve satisfied the needs of the customer. supply business will supply the size of the selected numerical data, so you can find under a given flow valve the paper thickness of the valve size. 6 mpa, but gap type check valve can achieve large caliber, DN can biggest to more than 2000 mm; Ball check valve ball check valves and practical in the low pressure pipe, can be made into large diameter; Ball check Industrial Valves shell material can be made of stainless steel, the health level of tightly closed a hollow spherical stereo molecular compound ptfe can package engineering plastic, to is in the same general corrupt media could also be used on the pipeline, temperature in - things 101 - - Between 150 ℃, its nominal pressure of 4 or less. In 200-0 mpa, nominal menstruation category 1200; Dealing with the compressibility of the fluid in check valve selection, first of all to the indispensable closed efficiency evaluation, the second step is to select or roughly satisfy the indispensable instances of check valve closing efficiency; Dealing with compressible fluid in check valve selection can certificate not compressibility of fluid with a check valve to hold the same points selection, category is very large, if the media activities are available for compressible fluid check a Marine valve to reduce the speed device, if the medium flows out in a row not quickly stop and start to work, such as the export of compressor that appearance, with rising land type check valve. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you. Second, if the valve has been selected by design unit of our company model, please order according to the valves parameters directly with our sales center. Three, it is very important when you use the occasion or the environment is more complex, would you please provide design drawings and detailed parameters, our engineers experts will concentrate on review and analysis for you.
