Product Description:

Hot Sells Forged Steel Piston ANSI Swing Flanged Check Valve 

 

Design Feature Of Hot Sells Forged Steel Piston ANSI Swing Flanged Check Valve:

 

The products feature a reasonable structure, reliable seal, good performance and nice modeling.

Either soft or hard seal can be selected for the product upon different working conditions. The sealing face is built up with Co-based carbide alloy, leaving a better wearability, corrosion and scrap resistance and a longer duration.

Small opening pressure, the disc can be opened fully with a very small pressure differential.

Inside-set bolt-bearing structure reduces leakage and reliable use.

Class≥1500LB, the middle cavity uses a self-tightening sealing structure to have the sealing performance reinforced along with the pressure rise so as to ensure the sealing performance.

Different parts materials and different sizes for flange, butt-welding are available for sensible combination according to different working facts and customers' requirement.

Q:Check valve and check valve
Check valve in English check valve, also known as check valve, the English non-return valve is the same valve different name
Q:Can the check valves fit two in one tube? One up, the other down
Launching, then you'd like to have a Sheung Shui at the front of the Sheung Shui
Q:How many kinds of structure are there in the check valve?
2. The swing check valve rotates around the shaft. Its fluid resistance is generally smaller than the lift check valve, it applies to larger caliber occasions. According to the number of valves can be divided into single swing type, double valve swing and multi valve swing type of three. Single swing check valves are generally applicable to medium calibre applications. Large diameter pipeline using single swing check valve, in order to reduce water hammer pressure, it is best to use water hammer to reduce the pressure of the slow closing check valve. Double check valves are suitable for large and medium diameter pipelines. Double check swing check valve with small structure and light weight is a kind of fast developing check valve. Multi valve check valve is suitable for large caliber pipeline;
Q:The check valve for the printer doesn't have any air in it, but it doesn't come out. It still doesn't work
1. Do you have ink in the ink cartridge? If not, you can't hit it;2, the ink box installation is in place, let the printer self check to see whether the instructions are normal;3, everything is normal, "maintenance" in the print head, not, deep cleaning;Generally normal, no, that might be a cup, change cartridgesIn addition, the check valve must be opened when printing, the cartridge is not placed high, and so on after processing
Q:What's the difference between the check valve and the stop valve?
Check valve is also called check valve or one-way valve, single-phase closed, individual hydraulic control one-way valve, plug valve also has a combination of controllable changes.The cut-off valve has the possibility of variable flow, two-way action, throttling possible, there can be two-way closed applications.
Q:If there is no check valve, there will be a reverse flow of water, what is the damage to the pump?
LZ said that the case does not matter with the check valve, in that case, in addition to affecting performance, it does not matter.
Q:Is the check valve installed at the inlet or outlet of the pump? Why?
The function of the check valve is to prevent the backflow of water and cause the phenomenon of air embolism, so the check valve is the water inlet of the water pump, and the first time the check valve must be filled with water above the check valve. In order to check the following air and water slowly discharged. Your phenomenon may be the pump power is too small, pressure can not open the check valve.
Q:The self-priming pump with check valve (check valve, water valve)?
Self suction pump reverse water valve is a check valve.Check valve refers to rely on the flow of the media itself and automatically open and close the valve flap, used to prevent media backflow valve, also known as check valve, one-way valve, counter flow valve, and back pressure valve. The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium. The check valve can also be used to provide a supply to the auxiliary system where the pressure may rise above the system pressure. The check valve can be mainly divided into swing check valve (rotating by gravity center) and lift check valve (moving along the axis).The function of this type of valve is to allow the medium to flow in one direction and to prevent flow in the direction. Usually the valve is automatically work, fluid pressure flow in one direction, the valve open; the opposite direction of fluid flow by gravity, fluid pressure and valve closing effect on the valve seat, thereby cutting off flow.
Q:What does the check valve "H44Y-160" mean?
H- check valve, 4 flange connection, 4 spiral structure, Y- sealing surface material is hard alloy. 160 table nominal pressure 16MPa
Q:The principle of the check valve
Check valve refers to rely on the flow of the media itself and automatically open and close the valve flap, used to prevent media backflow valve, also known as check valve, one-way valve, counter flow valve, and back pressure valve. The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium.
