Change the valve. The steps are divided into two kinds, one is to disassemble the old valve, the other is to install the new valve, the user needs to consider their own situation, such as the use of product design, specifications and sizes and the parameters of the scope of application to determine the method that can be taken to replace. So considering that many friends do not have any experience in this operation, the following gives you the method and steps of replacing the valve and the general purpose of the product, and the content of the second half has reference value for friends who are interested in purchasing.

1. Change the valve faucet.

How it works

1. How to disassemble the old valve core.

Method 1: Close the main water valve first, and then turn the faucet.

There is a red and blue mark of about 8 mm on the handle, buckle it down, loosen the fixing screw counterclockwise with a flathead screwdriver, remove the handle, and use a live wrench.

Disassemble the valve core of the faucet, use a wrench to open the upper part of the gland, and take out the ceramic valve core inside.

Method 2: Close the main water valve first, you can use a screwdriver to insert under the handle of the faucet, pry left and right, pry it on the side, take it slowly, and the force is even and stable, so that you can remove the valve core.

Method 3: Close the main water valve first, unscrew the blue cover on the right handle, loosen the screws inside with a Phillips screwdriver, take off the handle, and the valve core will be exposed, and then use a movable wrench to unscrew the valve core.

2. How to replace the new spool?

After removing the spool, you will see a blue rubber ring on the bottom of the spool. It is generally customary to have a red rubber at the bottom of the left spool, while a blue rubber on the right spool. Therefore, when changing the valve core on the right, it is still necessary to use the blue rubber valve core, after the valve core is installed, the handle is plugged in, and the direction of the handwheel is adjusted.

Attach the screws and close the blue cap on the right, so that the new spool is replaced.

Second, how much does it cost to change the valve?

1. Ball valve welding.

Ball valves. **：

The pricing of replacement valves on the market varies greatly, which can mainly refer to the technical level of the manufacturer, the quality of the product, the specifications and sizes, the fields suitable for use, etc. In addition, there are many things that need to be paid attention to about the operation of a better valve, such as the steps of disassembling the old valve core, the precautions for replacing the new valve core, etc., which play a key and decisive role in the later effect.

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.

The maintenance station is limited, and the replacement is somewhat inconvenient, that's for sure. However, I noticed that there is a union at the rear butt of the ball valve, and the docking is a certain flexible PPR pipe, so it may be troublesome at that time, and the ball valve can still be replaced.

1. Cut off the water. 2. Loosen the union nut at the ball valve in a closed manner.

3. Remove the valve handle to avoid the handle blocking the rotation of the ball valve around the pipe shaft during the replacement process.

4. Use pipe wrenches and other related tools to remove the ball valve, and you may need to pull the PPR pipe back (right) a little bit to take out the ball valve.

5. There should be a direct head of the internal thread to the external thread in the ball valve, which is screwed out.

6. Install the ball valve of the same type according to the steps, and use the raw material belt at the corresponding threaded connection.

The main difficulty should be when screwing in the ball valve, as the ball linkage may push against the tiles at the back, making it difficult to align the threads.

You can also consider installing a three-piece stainless steel ball valve (pictured below), if the valve is damaged, you can remove and replace the middle assembly.

Have you ever thought about how to remove it if something goes wrong after installation?

You should be okay to unload this, but it shouldn't be so easy to install when you put a new one back on.

There is a live connection in the back, which can be replaced and repaired.
