I have used Volkswagen copper ball valves, I don t know if Volkswagen has a PPR valve?

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.

I don't know if Volkswagen has a PPR valve, but I have a production on my side.

The outer diameter of the body of the PPR union copper ball valve is not the same at all, and only the welded pipe made of PPR material is unified.

If it is produced according to the national standard, the thread buckle of different manufacturers is the same.

In terms of cost performance: first, brand, second market share, third sales, fourth project evaluation; Quality product ranking: Amico, Edgedun, DunAn, Jackron, Ropes, Ropes, Ri'an.

001 Amico.

002 Jack Dragon.

003 Ning Anchor.

004 Nanyang.

005 Crown.

006 Yongdexin.

007 Ropes & Gray.

008 Lishui.

009 DunAn.

010 Jimbo.

Basically, there are not many fakes, and many of them are counterfeits.

Jimbo can, ***, good service.

With the PPR pipe, there is a double-live cast copper globe valve, as evidenced by the figure

The double-active globe valve is a copper ball valve, and there is PPR at both ends, and the PPR is fastened with wire! Detachable.

Double-live shut-off valve.

It is a copper ball valve with PPR at both ends. It is threaded with a middle flange.

The two ends of the branch pipe are flanged connections.

structure, which can be used with imported equipment.

Connection method: 1, PPR and double-active cast copper globe valve directly adopt hot-melt connection, and ordinary cast copper globe valve to add two supporting PPR inner (outside) filament street, change the ordinary cast copper globe valve to double-active cast copper globe valve, and then connect.

2. If it is a large diameter, replace the joint with a flange and connect it.

Turn off the main valve, remove the broken valve, take the valve to the market, and buy one in reference to the broken one. When removing the valve, pay attention to measuring the distance between the connections on the pipe. Otherwise, the valve bought back cannot be installed.

1. The rust in the pipeline gathers on the ball, and after a long time, it sticks firmly to it, increasing the torque of the valve switch.

2. When you want to close the valve, the valve stem can be broken due to excessive force, and the valve stem can rotate freely.

3. Remove the packing gland (unscrew the pressure head on the valve stem), and the water will leak out from the side of the valve stem. (The function of the packing gland is to seal and lubricate).

4. I bought two valves with the same appearance from the market and wanted to install them, but I couldn't install them. It is not that the valve factory is to blame, but the valve interface model bought is wrong, the connection form of the valve is very many, and the reference standard is different for different interfaces.

The PPR ball valve is disposable, according to what you said, the stem and valve have been disengaged, and the ball valve cannot be disassembled, so it can only be replaced with a new one.

Because the original lock of the valve rod fails, the original fixing screw is unscrewed and the handle is removed, which will expose the metal handle rod on the valve and rotate it with a plier to close it. However, the original handle will be replaced, or a new valve will be replaced in the future.

Know the nature of the materials in the reactor and whether there are special requirements for the faulty ball valve, so only according to the general situation; 1. You can try to hit it directly, but if the valve stem is rounded, you can't bring the ball to spin when you hit it.

If the seat ring is broken, you can buy RPTFE or PEEK for the valve seat, which has better wear resistance and good mechanical properties, and can be used for a long time!

The reasons for this problem are: 1. The connection between the valve stem and the valve body is slippery or slippery.

The best solution is to simply replace the valve.

Of course, a palliative way is to remove the valve stem, treat it with a hammer and other tools, restore it to its original state, and then spray the rust lubricating oil at the valve.

It's obviously broken, and now most of the homes are pre-embedded pipes, valves, and small opening and closing space, and it is recommended to use elbows to connect them. It just affects the aesthetics. Call the installer and he can handle it for you.

Because the valve stem has been loosened, it can't be linked to the valve, how can it be closed, use pliers, if it's not this problem, then it should be that the ball valve inside is broken, and this has to be replaced.

Quite simply, does the water flow become smaller?

If there is no trace of getting smaller, you can also rotate it relatively easily, it must be that the handle is loose and buttoned.

No matter how you twist it, the ball with holes in it doesn't turn at all!

You can screw it with hand pliers, and replace it with a new one if it can't be repaired.

Inferior products are like this, change to a new one, don't try to be cheap.

It's not that the ball valve is not used, it is the landlord who bought inferior products, like this valve body, with a lifetime will generally not have any problems, unless the weather is too bad will affect the life, as for the rust you said, then you have to consider whether some parts are copper, the same size of the globe valve can be pressed, there is no strategy you said, if you want to change next time it is recommended that you buy a better brand, I use Cheng Sheng at home, their globe valve and ball valve are good in China. I hope you can buy something that you are happy with.

You can buy a patch by yourself and use a wrench to remove the original replacement.

The stem is broken, and the boss's main problem is in the stem.

My home is a PPR ball valve, I'm afraid of being bad, a total of 2 times, but recently I want to close the valve, but I found that the valve stem can rotate freely, but the valve can't be closed at all, I put the pressure head on the valve stem down, the water leakage. I bought two valves, but I found that the valves with the same appearance could not be installed! I heard from netizens that this is a strategy launched by different manufacturers, so that you can't use other people's things!

I want to repair it by disassembling it myself, but it still doesn't work well after repairing, and it's full of rust! I don't seem to understand, why is there rust in the obviously copper valve? I just want to change the valve quickly, but the most worrying thing is that the melting ppr is not long enough, which is disturbing!!

I don't understand now, why is the ball valve so inhibitable!?

As you described, the phenomenon is that the core is slippery, and it can only be replaced as a whole.

It may be that you haven't used it for a long time and it's blocked with dirt, and you can't change it.

Is it stuck, broken?

It's supposed to be broken, and I need to get a new one.

PPR ball valves are based on PPR pipe specifications. The specifications of the PPR pipe are based on the outer diameter of the pipe, such as the PPR pipe with an outer diameter of 20mm, because the wall thickness is different, it is divided into 4 specifications, such as 20*, 20*, 20* and 20*, but because the outer diameter of the pipe is the same, the specifications of the PPR pipe and the ball valve of the same outer diameter are the same.

After cutting the pipe, directly weld the 50 straight wire outer joint to screw the stainless steel pipe on, and it is best to wrap the raw material belt after twisting the pipe, so that the effect is the best.

Hope it helps.

There is PPR direct inner wire, that is, one end of the inner wire and the other end of welding.

The difference between the PPR ball valve and the PPR live ball valve is: between the two sides of the PPR live ball valve valve and the pipeline (hot melt) connection, a (hot melt) union and (link) nut are added, and it is convenient to disassemble and replace the valve during maintenance.
