In the H44H check valve, each symbol or number represents a different meaning. The first h, which represents the check valve. The second number, 4, indicates the connection method, which belongs to the flange connection.

The third number, 4, indicates the structure, which belongs to the structure of the spiral single lobe. And the last character h, which represents the material, represents the stainless steel sealing material.

Check valves, also known as check valves, are classified as automatic valve types. It can effectively prevent the reflux of liquids. Moreover, the disc has the function of closing quickly, the service life is very long, and the performance is also very good.

Attention should be paid to the installation of check valves.

1. In the process of arranging the pipeline, it is necessary to control the importance of the check valve, and try to be within the range of compliance, so as to avoid crushing. Moreover, the large check valve needs to have independent support, so that it will not be affected by the pressure generated by the pipe system and bring unnecessary trouble.

2. In the process of installing the check valve, it is necessary to pay attention to the flow of the medium, and try to make it the same place as the direction marked on the surface of the check valve, so as to ensure normal use.

3. If the vertical flap check valve is installed, special attention needs to be paid to ensure that it is perpendicular to the pipeline. If it is a horizontal valve, it should be placed on the horizontal pipe, so as to ensure that the check valve plays a normal role, and the use effect will naturally be more.

H41H-64 Check Valve Model Letter Meaning:

The first h represents the check valve;

The second 4 represents the flange connection;

The third 1 represents the check valve is a lifting valve plate, DC channel;

The fourth h represents that the sealing surface of the valve seat is stainless steel;

The number 64 represents the nominal pressure of 64 kg;

Therefore, H41H-64 represents a flanged connection with a maximum pressure of 64 kg lifting check valve.

The second H in the check valve H44H-16C indicates that the material of the seal is stainless steel, that is, the valve is hard sealed. H44H swing type steel stop valve is suitable for the pressure of -29 +550 working temperature of petroleum, chemical, manufacturing, fertilizer, power industry and other working conditions of the pipeline, the applicable medium is water, oil, steam, acid medium, etc. It is a valve that controls the unidirectional flow direction of the medium in the pipeline to prevent the medium in the pipeline from backflowing.

Check valve refers to the valve that automatically opens and closes the valve disc by relying on the flow of the medium itself to prevent the medium from backflowing, also known as check valve, check valve, reverse flow valve, and back pressure valve. The check valve is an automatic valve, and its main function is to prevent the backflow of the medium, prevent the pump and the drive motor from reversing, and the discharge of the container medium.

Check valve H41W-16P refers to the name of the valve and the model number of the valve.

Check valve model compilation method (in order: H41W-16P).

Check valve type: H generation change table check valve.

Check valve connection: 4 flanges, 6 welds, 7 pairs of clamps.

Check valve form: 1 lifting type, 2 vertical type, 4 rotary opening type, 6 double valve type, 8 butterfly type.

Check valve seals: B babbitt, F fluoroplastic, H stainless steel, M monel, X rubber, Y carbide.

wDirect machining.

Check valve pressure.

Check valve material: T stands for cast iron, H stands for cast steel.

W stands for stainless steel and Y stands for tungsten carbide.

Check valve refers to a kind of valve that has a circular disc opening and closing parts and relies on its own weight and several ballast medium pressure to block the backflow of medium. It is an automatic valve, also known as check valve and check valve.

Return valves or isolation valves. The disc movement mode is divided into lifting type and swing type. Lifting check valves and globe valves.

The structure is similar, with only the stem that drives the disc missing. The medium flows in from the inlet (bottom) and out from the outlet (top). The valve is opened when the inlet pressure is greater than the sum of the disc weight and its flow resistance.

On the contrary, the valve is closed when the medium flows backwards into the nucleus. Swing-open check valve.

There is a disc that is angled and rotates around the shaft and works similarly to a lift check valve. Check valves are often used as foot valves for pumping devices to stop the backflow of water. The check valve is used in combination with the globe valve to play the role of safety isolation.

The disadvantage is that the resistance is high and the sealing is poor when closed.

H stands for check valve, 4 stands for flange, 1 stands for lifting, T means sealed, and 16 stands for pressure.

h represents check valve, 4 represents flange 1 represents form 16 represents pressure This is a cast iron lift check valve.
