A special gas valve is a type of valve used to control and regulate the flow of special gases. Specialty gases usually refer to gases that have some special components added to ordinary gases, such as inert gases, gas mixtures, etc. Special gas valves usually use high-precision control systems and materials to ensure their accuracy and stability in controlling and regulating the flow of special gases.
These valves usually have the characteristics of high strength, corrosion resistance, good sealing, etc., and can adapt to a variety of harsh industrial environments. Special gas valves are widely used in semiconductor, optoelectronics, aerospace, medical and other fields, such as chemical vapor deposition (CVD) and physical vapor deposition (PVD) processes in semiconductor production, vacuum evaporation process in the manufacture of photoelectric display devices, fuel filling and exhaust emission control in aerospace, etc.

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:
The following influential first-line brands of water system valves and industrial valves can be used as a reference, but for reference only: Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Su Yan, 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.
These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

wcd?It should be a WCB valve, which has a steel sewage valve, which is the valve that mainly takes the medium of sewage, and there are two common models of fast sewage valve: Z44H and P48H.

The 44 blowdown valve is an open rod balanced double ram.
48 blowdown valve is a dark rod balanced double gate.
The biggest difference between these two types is that one is a bright rod and the other is a dark rod.
The structural form code of the gate valve.

Z41H-25C is a cast steel gate valve with a pressure of 25 kg. Here's an explanation of what each character in this model means.
Z represents the gate valve, 4 represents the flange connection, 1 represents the open rod structure, H indicates that the sealing surface is made of stainless steel, 25 indicates that the maximum pressure of the valve is 25 kg, and C indicates that the valve body of the valve is made of carbon steel.
-
Z is the gate valve (the first letter of zha), 4 is the flange connection, 1 is the open rod wedge rigid single gate, h is the material code of the valve seat sealing surface or lining (the first letter of the alloy steel of HE) 25 is the nominal pressure of the valve, that is, the maximum working pressure under normal operation is 25 kg, and the one with C behind it should be cast steel.
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. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves, etc.), chrome-molybdenum steel valves, chrome-molybdenum vanadium steel valves, duplex steel valves, plastic valves, non-standard customized valves, etc.
The valve is a control component in the pipeline fluid transportation system, which is used to change the channel section and the direction of medium flow, and has the functions of diversion, cut-off, throttling, check, diversion or overflow pressure relief. Valves for fluid control, from the simplest globe valves to the most complex automatic control systems used in a variety of valves, its varieties and specifications, valves from the very small instrument valve to the diameter of 10m for industrial pipelines.

The working condition of the blowdown valve is different from the ordinary situation, and there will be corrosion, wear, etc., so the ordinary ball valve will not work if it is not anti-corrosion and wear-resistant. Moreover, if the switching frequency of the blowdown valve is relatively large and the colleague needs a long life, the structure and material selection of the ball valve will be different.

I don't know what kind of salt there is.

Your model number should be written wrong, or I am lonely, it should be D671F, this model means butterfly valve (D) pneumatic (6) clamp type (7) sealed type center line type (1) lined fluoroplastic (F). There should also be a pressure number and the code name of the body material. For example, D671F-10C is followed by 10 kg (or C is for carbon steel.
