Specification, price and manufacturer introduction of gate

Valve is the most common industrial equipment, its main function is to control the fluid delivery system, and its characteristics are also very obvious, such as very shut-off, adjustment, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. It is precisely because of this characteristic that the valve can effectively control air, water, steam, various corrosive media, mud, oil and liquid metal. But many friends are not very familiar with valves, so let's talk about valves, hoping to help you.

Valve specification

DN means check valve, which is a kind of valve.

15. This is the specification of the valve. 15 means that this valve can be connected to a water pipe with a diameter of15 mm. 20 and 25 are the same as 15. The difference is that these two figures refer to the diameter of 20 mm and 25 mm water pipes.

4. Main pipe refers to the pipe with the diameter of 15 mm, and the actual pipe diameter is15.4 mm. In practical application, the numerical value after the decimal point is of little significance, so, except for accurate calculation, most of them take the approximate value of15 mm..

6 main pipe refers to a water pipe with a diameter of 20 mm, with an actual diameter of19.7 mm.

1 inch pipe refers to a water pipe with a diameter of 25, with an actual diameter of 25.4 mm ..

1.5 inch diameter is 40 mm, 2 inch diameter is 50 mm, 3 inch diameter is 75 mm and 4 inch diameter is 100 mm. ..

Valve price

The valves used in the fluid control system, from the simplest cut-off valve to various valves used in the extremely complicated automatic control system, have quite a variety of varieties and specifications. Valves can be used to control the flow of various fluids, such as air, water, steam, corrosive media, mud, oil, liquid metal and radioactive media. Valves are divided into cast iron valves, cast steel valves and stainless steel valves (20 1, 304, 3 16, etc. ), chrome-molybdenum steel valves, chrome-molybdenum steel valves, dual-phase steel valves, plastic valves, non-standard customized valves, etc.

The above is the knowledge about valves introduced by Xiaobian. The valve has a good effect on fluid control. Moreover, the appearance of valves has greatly improved the efficiency of industry. The valve is not only convenient to operate, but also very safe to use. It is for this reason that it is very effective in controlling water, oil, steam and liquid metal. In addition, the flexibility of the valve is also very good, but we must pay attention to the maintenance of the valve when using it, otherwise the valve will be easily damaged or seriously deformed.
