Butterfly pneumatic valve gb model description < / div >

we there are many different kinds of pneumatic valve industry, the most commonly used pneumatic valve is a butterfly, a national standard butterfly pneumatic valve, butterfly valve, pneumatic valve, butterfly for sinopec below small make up to, in a nutshell, we commonly used national standard adjustment model of pneumatic valve, allowing you to look at a model to understand this adjustment the specific structure of the pneumatic valve, connection, material and so on, even if not understand pneumatic valves have you seen also probably understand butterfly pneumatic valve type.
first we will know how to prepare a butterfly, the make and model of the pneumatic valve pneumatic valve gb model is a complete adjustment by D ( On behalf of the butterfly pneumatic valve) + + connection + pneumatic valve drive pneumatic structure + pneumatic valve seat seal form + pressure pneumatic valve, pneumatic valve body material, so is a complete the pneumatic butterfly valve type, I again for concrete under the meaning of each number represents. A pneumatic valve, butterfly we are all in capital' D】 First letter said, so pneumatic valve pneumatic valve is D means is a butterfly. Second, pneumatic valve, transmission way is refers to the way we butterfly pneumatic valve open closed: manual ( Blank) , 3: turbine drive, 6: pneumatic transmission, 9: electric connection symbol: 4: flange connection, 6: welding connection, 7: four connected to the clamp, pneumatic valve structure symbol: 1: line form, 2: double eccentric forms, 3: triple eccentric form five, pneumatic valve seat seal form symbol: H: hard seal, X: four fluorine soft seal, F: line 6, pneumatic valve pressure symbols have national standard butterfly valve ( PN) And the adjustment of pneumatic valve ( Said the class) Points: butterfly gb pressure pneumatic valve symbol: 10:10 kg, archite, kg, kg, 40:40 kg when butterfly pneumatic valve American standard pressure symbol: 150 lb: 16 kg, 300 lb: 25 kg 【 LB on behalf of the butterfly pneumatic valve American standard unit 】 Seven, pneumatic valve body material symbols: Z: cast iron ( May also directly bring a blank) , Q: ductile iron, C: cast steel, P: stainless steel 304, R: stainless steel 316 is more than common butterfly pneumatic valve gb model shows that: for example, D941X - 10 p【 D941X- 10 p】 Butterfly: D 9 said electric, pneumatic valve, flange, 4 said 1 line form, soft seal, 10 X said said 10 kg pressure of 304 stainless steel material, P said hope the above explanation of butterfly pneumatic valve gb model can help to you, said the relatively simple, if you encounter more complex type also can ask our technical small make up directly.
