D371X 1 0 500 indicates what valves

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.

Indicates a soft-seal butterfly valve for the clamp type.

The desulfurization handle clamps the ball disc of the butterfly valve.

Desulfurization to clamp butterfly valve, valve plate.

It is only known that it is the handle to clamp the butterfly valve.

No. It is a pinch valve.

valves

The total of mechanical products with movable mechanisms used to control the medium in the pipeline.

Valves can be made by structureClassification, butterfly valve is a type of valve.

Butterfly valvesThe opening and closing parts (butterfly plates) are valves that are driven by the valve stem and rotate around the axis of the valve stem.

Valve connection formVarious ways of connecting valves to pipes or equipment (such as flange connection, threaded connection, welded connection, etc.). Ask the so-calledFlanged valvesThat is, the valve that is connected as a flange connection.

According to the valve model preparation method recommended by China's machinery industry standard JB T 308 "Valve Model Preparation", in the butterfly valve model D371X-10 DN100, the third digit "7" indicates that the connection form is "clamp", and the flange connection is identified as "4".

FlangesIt is a part that is connected to each other between shafts and is used for the connection between the ends of the tube. Flange connection orFlange joint refers to the detachable connection of flanges, gaskets and bolts connected to each other as a group of combined sealing structures.

The following is the flange and the flange connection butterfly valve

Due to the small size of the front and rear of the butterfly valve, it can be clamped and installed between two flanges like a gasket in a flange connection on some occasions, i.ePair clamp connection。The following picture shows the installation of butterfly valve clamp control.

Note: Some pair clamp valves have a flange-like structure, but instead of a flange, it is a locating hole.

No, this model is a turbine-to-clamp butterfly valve, and the flange valve refers to the flange plate on the valve body to connect.

According to your model name, it should be the right butterfly valve.

Valve D37L1X: D represents butterfly valve, 3 represents worm gear transmission, 7 represents clamp type, 1 represents mid-junction type, and X represents sealing surface material.

The valve (famen) is a control component in the fluid transfer system, which has 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.

According to the provisions of the "JB T 308-2004 valve model preparation method".

d== butterfly valve.

3== Worm gear drive.

7== Pair clamp type.

1== Mid-junction type.

x== Sealing surface material: rubber.

The difference between the D37L1X and the D371X is that the D37L1X disc is made of stainless steel and is more sealed (the seat is still rubber), while the D371X disc and seat are rubber sealed. See image below
