16kg floating ball valve, construction length is 280mm

DN refers to the diameter of the male car, DN100 is the inch flange: the outer diameter of the flange is 220mm, the bolt hole spacing is 180mm, the bolt diameter is 18mm, the number of bolts is 8, and the flange thickness is 22mm. It is specified as a flange size table (GB9119).
-
1. Due to historical reasons, some length units still use the unit of inches. The conversion between inches and metric (also known as meters) is: 1 inch = millimeter = 8 cents, and DN10 is equivalent to 3 cents in the metric system.
Others, such as: DN25 is equivalent to 1 inch in the British system; DN20 is equivalent to 6 points on the British scale; DN15 is equivalent to 4 points on the British scale; --Wait a minute.
2. DN10 is the difference code of pipe diameter, which does not represent the outer diameter or the inner diameter, and cannot be used for calculation.
-
DN10 refers to the valve whose mouth is very ten millimeters and should be three points, as shown in the figure below, the diameter is eighty millimeters, and the pressure is sixteen kilograms.
-
This valve size chart is for you! DN10 = 3 8 inches.

DN50 valve corresponds to a diameter of 2 inches, that is, a diameter of 50mm.
A valve is a pipeline attachment used to open and close pipelines, control the flow direction, regulate and control the parameters (temperature, pressure and flow rate) of the conveyed medium. According to its function, it can be divided into shut-off valves, check valves, regulating valves, etc.
Valves are control components in fluid transportation systems, which have the functions of shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves for fluid control systems range from the simplest shut-off valves to the most complex valves used in automated control systems.
Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, slurries, oils, liquid metals and radioactive media. According to the material, the valve is also divided into cast iron valves, cast steel valves, stainless steel valves, etc.), chromium-molybdenum steel valves, chromium Wanghe molybdenum and vanadium steel valves, duplex steel valves, plastic valves, non-standard customized valves, etc.
The valve model should usually indicate the valve type, drive mode, connection form, structural characteristics, sealing surface material, valve body material and nominal pressure and other factors. The standardization of valve models provides convenience for the design, selection and sales of valves. Nowadays, there are more and more types and materials of valves, and the type preparation of valves is becoming more and more complex.
Valve model preparation method":
The standard is applicable to gate valves, throttle valves, ball valves, butterfly valves, diaphragm valves, plunger valves, plug valves, check valves, safety valves, pressure reducing valves, trap valves, etc. It includes the model compilation of the valve and the nomenclature of the valve.
The specific preparation method of the valve model, such as the valve model: "Z961Y-100IDN150", this is a complete gate valve model, and the preparation does not include the final "DN150", which is the meaning of the valve diameter of 150mm, which is easy to understand. Front Section:
Z961Y-100i" is seated according to the sequence diagram above, as follows:
Z" is 1 unit; "9" is 2 units; "6" is a 3-unit; "1" is for 4 units; "Y" is for 5 units; "100" is 6 units; "i" is the meaning of the valve model of unit 7: gate valve, electric drive, welded connection, wedge single ram, cemented carbide seal, 10MPa pressure, chromium-molybdenum steel body material. <>

Summary. DN50 gate valve on how big the flange head, dear, hello is happy to answer for you, 50 gate valve with ppr63 flange piece. Because the inner diameter of the PPR63 pipe is 50 mm, the nominal diameter and inner diameter of the 50 gate valve is 50 mm, and because of the nominal diameter of the valve with the nominal diameter of the pipe in the pipeline installation specification.
That is, the 50 gate valve should be equipped with a PPR63 pipe. This is because the inner diameter of the flange of PPR63 is 63 mm, while the outer diameter of the tube of PPR63 is 63 mm. So 50 gate valves use FPR63 flanges.
DN50 has a large flange head on the gate valve.

You can follow my steps to try it, and if you have any questions, you can give me feedback in time!
How big is the PE flange head.
You can follow my steps to try it, and if you have any questions, you can give me feedback in time!
Dear, hello, I am glad to answer for you, DN50 pipe fittings with PE50 pipe is just right. Because the inner diameter of the PEDN50 pipe is 50 mm, and the outer diameter of the PE50 pipe is 50 mm, then the inner diameter of the PEN50 pipe fitting and the outer diameter of the PE50 pipe are exactly the same. Therefore, DN50 fittings with PE50 pipes are just right.
For example, the pipe fittings of PEDN63 are suitable for PE63.
