What does the globe valve model J21W 16C mean

This is another form of numbering, J21W needle valve, also known as external thread globe valve, external thread needle valve, external thread needle valve, the connection method is welded, and the connection with the valve body adopts external thread union type, so it is also called external thread globe valve. The latter is generally 16p, which represents 16mpa, and 16c has never been seen

Hello! Needle globe valve, male threaded connection, nominal pressure 16 kg, C for carbon steel.

Hope it helps, hopefully.

J in the globe valve model J61Y-25 refers to the globe valve, 6 refers to the connection method, 1 refers to the straight-through structure, Y sealing surface material, cemented carbide, and 25 refers to the nominal pressure.

The globe valve model is a symbol and number to indicate the structure and performance of the globe valve. The globe valve model is generally composed of the following 7 units: such as (WJ41H-16C).

Additional code for globe valves: W bellows, D low temperature, B insulation, ordinary omitted.

Unit 1 - Use the Chinese pinyin letter (j) to represent the structural category of the globe valve: for example, j represents the globe valve.

Unit 2 - use one digit to indicate the driving mode of the globe valve: such as 0 electromagnetic, 6 pneumatic, 9 electric, the unit code can be omitted when it is generally manual.

Unit 3 - Indicate the connection between the globe valve and the pipeline with one digit: such as 1 internal thread, 2 external threads, 4 flanges, and 9 ferrule connections.

Unit 4 - use one digit to indicate the valve structure type: such as 1 straight-through, 2 Z-type straight-through, 3 tee, 4 angle type, 5 Y type DC type, 6 balanced straight-through type, 7 balance angle type, etc.

Unit 5 – Indicate the material of the sealing surface or lining of the valve in Chinese pinyin. Such as F fluoroelastomer, H stainless steel, Nylon plastic, Y cemented carbide, M Monel alloy, T copper and copper alloy, W valve body direct processing.

Unit 6 – The nominal pressure value is directly expressed in Arabic numerals, which is 10 times the MPA, and is separated from the first 5 units by **.

Unit 7 - Use Chinese Pinyin code letters to represent the valve body material. Such as A titanium alloy, C carbon steel, I chromium molybdenum steel, P stainless steel 304, R stainless steel 316.

J11W-10T globe valve Hongxin, J Intercept rubber check valve, 1 internal thread connection, 1 straight flow channel, W sealing surface is body processing, 10 nominal pressure PN10, T body material is copper alloy.

J--indicates the valve type (globe valve); 1. --- connection form (internal thread) beam is peerless; 1--Structural form (straight-through); h--nitric acid corrosive medium); 16--Pressure level (16MPa); p--Body material (Incontinol).

Globe valve: Globe valve, also known as globe valve, is a forced sealing valve and is one of the most widely used valves.

The globe valve relies on the pressure of the valve bar to make the sealing surface of the valve disc and the sealing surface of the valve seat fit tightly, preventing the flow of the medium, because only the medium is allowed to flow in one direction, so the installation is directional. Globe valves can be divided into direct flow globe valves, angle globe valves, plunger globe valves, upper threaded stem globe valves, lower threaded stem globe valves, etc., they have durable, small opening height, easy to manufacture, convenient maintenance, not only suitable for medium and low pressure, but also suitable for high pressure.

According to the provisions of "JB T 308-2004 Valve Model Preparation Method".
