28, the owner of Furong Mountain in the snow Liu Changqing is far away in the twilight, and the white house is poor in the cold weather.

D is the butterfly valve, 4 represents the flange connection, 0 does not know what it means, generally it should be 1, the middle line, J stands for the rubber liner seal, 10 represents the working pressure of 10 kg, and C represents the valve body made of cast steel. Shuangde valve Xiao Li will answer for you, I hope it can help you.

There are many types of valves, so each valve has a specific model. Butterfly valve D41X-16 code D refers to butterfly valve, 4 refers to the connection form is flange, 1 refers to the driving mode is manual, X is the material of the valve sealing ring is rubber, 16 refers to pressure, 16 kg. The model of the valve is made up of seven elements:

Valve type, connection form, drive mode, structure, sealing ring material, nominal pressure, material. If you don't understand, you can ask me. [Double special valve].

In the case of the national standard, D is a butterfly valve, 4 is a flange connection, 1 refers to the center line structure, X is a sealing form of EPDM rubber seal, and 16 is a pressure of 16 kg.

D Butterfly valve 41 flange connection x rubber seal 16 kg pressure.

d--- stands for butterfly valve; 4--- refers to the flange connection form; 1--- refers to the valve stem and butterfly plate of the valve on the center line of the valve body, without eccentricity; W--- means that the material of the valve seat is the same as the material of the valve body, which is generally carbon steel. The last 1 --- refers to the nominal pressure of 1 kilogram square centimeter.

This butterfly valve is called ventilation butterfly valve in our factory, 4 represents the connection French is flange to flange connection, 41 in 1 represents the midline butterfly valve, W stands for body seal, that is, C is cast steel, in fact, the correct model of this should be D41W-1C. It is suitable for ventilation, flue gas and other media.

J stands for sealing surface and inner diameter lined with rubber, and rubber lined butterfly valve.

Generally, disc valves are unidirectional, which means that the input and output are specified. There are arrows on general one-way butterfly valves.

Bidirectional means that there are no input and output regulations, and it can be installed as it is. (Generally only used in places where the pressure is not too high).
