What does the gate valve model DN25X155 mean

DN25 caliber, X155 is not a model Is there a ** sent over to verify.

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.

Z45X-16Q, Z represents gate valve, 4 means flange connection.

5 refers to the dark rod gate valve, X refers to the rubber seal, and 16 refers to the nominal pressure.

RVHX means manual gate valve, 150 refers to the caliber of DN150, and 10 represents the nominal pressure. RVHX Dark Rod Resilient Seat Seal Gate Valve was the first to be crowned.

The valve factory is a special model, and the Z45X is a national standard model.

It is indicated that the rubber soft seal open rod gate valve,Flange connection, pressure 16 kg, body materialDuctile iron

Split the model number apart:

Z represents the gate valve, 4 represents the flange connection, 1 represents the open rod wedge single ram structure, X represents the sealing surface material is rubber, and 16 represents the nominal pressure.

is 16 kg, and Q indicates that the body material is ductile iron.

Merit. 1. Low flow resistance. The medium channel inside the valve body is straight, and the medium flows in a straight line, and the flow resistance is small.

2. It is more labor-saving when opening and closing. Yes with shut-off valves.

In contrast, the direction of movement of the ram is perpendicular to the direction of the medium flow, whether it is open or closed.

3. The height is large and the opening and closing time is long. The opening and closing stroke of the ram is larger, and the lifting is carried out by the screw.

4. Water hammer.

Not easy to produce. The reason for this is the long closure time.

5. The medium can flow in any direction on both sides, which is easy to install. The gate valve passage is symmetrical on both sides.

6. The length of the structure (the distance between the two connected end faces of the shell) is small.

7. The shape is simple, the structure length is short, the manufacturing process is good, and the application range is wide.

8. The structure is compact, the valve has good rigidity, the channel is smooth, the flow resistance is small, and the sealing surface is made of stainless steel and cemented carbide.

Long service life, PTFE packing, reliable sealing, light and flexible operation.

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.
