Which is the best manufacturer of valves in Shanghai? There are many valve manufacturers in Shanghai, specifically which one is the best, in fact, it is very difficult, this depends on where you can evaluate it conveniently, each manufacturer produces different valve products, and the fields involved are also very different, for example, some are doing water systems, some are doing industrial systems, and industrial systems are divided into many fields, such as: electric power, chemical industry, petroleum, pharmaceuticals and many other fields.
Here is a brief introduction to a few companies, Shanghai Qizhong valve in the field of water system, Suzhou Neway valve, Shanghai Guanlong valve this unit is not bad, industrial valve field can also be.
Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. Although the ranking may change due to time and market conditions, the following brands are generally considered to be one of the top brands in the valve industry: water system valves and industrial valves The following more influential first-line brands can be used as a reference, and the following are the top ten domestic first-line valve brand manufacturers in 2022-2023, but for reference only:
Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Suyan, Shentong, Su Valve, Nanfang, Jiang.
First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.
-
High-pressure needle valve with a diameter of 10 mm.
-
J61Y: Welded straight-through globe valve, PW54 17: Working pressure at operating temperature 540.
v: Chromium, molybdenum, vanadium, and vanadium.
If you don't understand the valve number, it is recommended to look at JB T308-2004
-
J--- globe valve 6--- welded type 1 -- straight-through y--- cemented carbide seal.
The use temperature is 540°C and the nominal pressure is 170kg cm2 of superalloy globe valve.
-
w- indicates that the sealing surface is the body material.
-
Power station shut-off valve, I don't know what it means.
-
The gate valve has z60w, and "0" is the elastic ram.
There is no J60W for globe valves, see "JB T 308-2004 Valve Model Preparation Method" for details.
-
It should be J961Y-P54 140V
J961 electric butt welding straight stop valve, Y cemented carbide (Stellite) sealing material, P54 working temperature is 540 degrees, working pressure 14MPa, valve body material CRMNV steel.
-
Generally, DN10 is a hose with 10 inner diameters, and DN German standard joints are used for assembly, and KJ10 is a hose with 10 inner diameters, and national standard joints are used for assembly.
-
J23W: Globe valve, manual opening, straight-through. Screw drive.
160p: The working pressure of the valve does not exceed 16MPa (160kg).
DN10: The nominal diameter of the valve is 10mm.
-
J - valve type code (globe valve).
2 - valve connection end connection form code (external thread connection) 3 - valve structure form code (three-way flow channel).
W - sealing surface material code (sealing sub materials are valve body) 160 - pressure code or working pressure code at working temperature (pressure level, 16MPa) P - valve body material code (chromium-nickel stainless steel, P generally refers to 304) DN - nominal diameter.
10 - caliber size (10mm).
The above is the meaning of each position, and this is generally the case with general-purpose valves.
-
The second floor is right, but! The globe valve has a three-way ??
-
This is not a standard, it should be the model or serial number of a certain brand of valve.
-
J: Globe valve 6: Welding 1: Straight-through Y: Cemented carbide I don't know later, it may be the factory standard!!
Hello,The United States imported electric high-pressure globe valve brand manufacturer: Keen Ke KNKEGlad for your question. >>>More
It's really rare for people to do this.
The national standard globe valve is a forced sealing valve, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak. When the medium enters the valve from the bottom of the valve disc, the resistance that needs to be overcome by the operating force is the friction between the valve stem and the packing and the thrust generated by the pressure of the medium, and the force of closing the valve is greater than the force of opening the valve, so the diameter of the valve stem should be larger, otherwise the failure of the top bend of the valve stem will occur.
Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry: >>>More
The opening and closing parts of the stop valve (globe valve) are plug-shaped discs, which are flat or sea cone surfaces on the seal, and the disc moves in a straight line along the center line of the valve seat. The movement form of the valve stem, (common name: dark rod), there are also lifting and rotating rod types, which can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. >>>More
