With the upgrading of the industrialization era at home and abroad, valve product types and materials used are emerging in an endless stream, and valve model compilations are also increasing. Valve models provide a lot for users to purchase valves. Convenience, it also ensures the safety of use, and enables more precise selection. Although there are a series of valve preparation methods in China, some factories still produce their own factory standards, but as long as they do not deviate from the valve preparation standards, the product category can still be identified. When compiling the valve model, the valve category, driving method, connection type, Market Brass Ball Valve pipeline structure, rated pressure, sealing and valve body materials should all be described. The meaning of the valve model should be composed according to the following arrangement.
Valve category-drive method-connection method-valve structure-sealing material-used pressure-valve body material such as Q41F-16P What does it mean? The Q41F-16P model disassembled is the following meaning: Q-ball valve-here is empty, that is, manual 4-flange connection 1-through F-soft seal 16-PN16P-stainless steel 304 material valve model can be applied to all kinds of gates , Cut, stop, butterfly, ball, cock, plunger, pressure reducing, water barrier, safety valve and other different products. It is very convenient for manufacturers to classify products and product positioning on a large scale. 1. Valve category (model designation) 2. Valve driving method (model designation)
3. Valve connection type (model designation) 4. Valve structure (model designation) Butterfly valve structure model meaning Gate valve structure model meaning Ball valve structure model meaning Check valve structure The meaning of the model is the meaning of the cut-off, throttling, and plunger valve. The meaning of the structure of the diaphragm and the plug valve is the meaning of the safety valve structure. The meaning of the pressure reducing valve is the meaning of the trap valve.
6. Valve pressure (model designation) The value in the valve model represents the nominal pressure value, which needs to be represented by Arabic numerals. 1MP is PN10. 7. Valve body material (model designation)
