Wat is better yn Water Valve? Stop Valve of Ball Valve

Hoewol ûntwikkelders ynstalleare in haadwetterklep yn 'e piipput yn' e korridor foar elke húshâlding by hûsrenovaasje, de behearsput is faak ticht, and the residents themselves cannot open this pipe well to control the water pipes in the home, so they will add an indoor main water valve under the kitchen sink during renovation. This makes it possible to keep the water pipes in the house closed at all times and in all places, facilitating daily maintenance. A selective question arises: Is it better to install a shut-off valve or a ball valve on the PPR main pipe?

Which should be chosen:When installing shut-off valve or ball valve on PPR main pipe

To determine whether it is better to install a stop valve or a ball valve on the water PPR main pipe, I think it is necessary to analyze in detail from three aspects: the characteristics of the two valves, the material of the water valve, and the convenience of maintenance and replacement in the later stage, so as to get a comprehensive answer.

Characteristics of shut-off valve & ball valve

Both stop valves and ball valves can be installed on the main PPR water pipe as valves, so to know which one is better, start with the characteristics of the two valves.

Stop valve: Stop valve is a rotary opening and closing valve that uses the closing principle to control the opening and closing of the valve. There is a Z shape inside the stop valve, and the pressure of the stem is used to make the sealing surface of the disc and the sealing surface of the valve seat fit tightly, and the opening and closing are achieved by the lifting and lowering of the gasket valve core.

Advantage of stop valve

1. Good fluidity. Due to the unique design inside the stop valve, it is less likely to be blocked by debris in the water when the valve is open, so it has good fluidity;
2. Easy to maintain, as the design principle of the stop valve is simple and there is no overly complex structure, it is very convenient to repair;
3. Good sealing performance. Since the sealing design of the stop valve is inside, there will be no damage caused by use and wear, which naturally ensures the integrity of its sealing performance. Because of these advantages, many people choose to use the stop valve as the main water valve for PPR water pipes during decoration.

Ball valve: Ball valve is a type of valve that uses a hole in the center of a ball as the valve core, and controls the opening and closing of the valve by rotating the ball valve core. There is also a clear definition of ball valves in the national standard GBT21465-2008. And there are many types of ball valves used on PPR tap water, so special attention should be paid in this regard.

Advantage of ball valves

1. Easy to install, especially for the ball valves without union available on the market now;
2. Good sealing performance, as the ball valve is designed with a ball core inside, it has good sealing performance;
3. Moderate price. One of the important reasons why many people like to use ball valves nowadays is the wide variety, strong selection and moderate price;
4. Low flow resistance when opening and closing by rotating the ball valve core, the ball valve has the least flow resistance among all valves.

Material of the water valve

The main reference factor for choosing whether to install a stop valve or a ball valve on the main PPR pipe for tap water is the material of the valve, which is also a key point that directly affects which valve to use.

Material of the stop valve

For the stop valve used on the main PPR water pipe, copper and stainless steel are the most commonly used materials at present, and there is basically no significant difference between these two materials, which can be chosen by yourself. But only two materials are recommended for PPR water pipes, only in this way can the quality of the fittings be guaranteed. At this point, you can choose one of them based on your personal usage habits and preferences, as well as the common types used by plumbers. Here it should be noted that the quality of the stop valve varies greatly. Even when used on the main PPR water pipe, there is a significant quality difference. It is recommended to purchase a stop valve produced by a big brand merchant that costs around 100 yuan. This is the best and most suitable stop valve.

Ball valve material

For ball valves, there are many types available on the market for PPR water pipes, including PPR one-piece formed ball valves and PPR live ball valves. And among PPR one-piece ball valves, there are two types, with and without union, so it is particularly important to distinguish them. For now, PPR one-piece ball valves without unions are being phased out because they are disposable products and cannot be replaced or maintained; The PPR type ball valve with a union, although replaceable, is far from meeting the standard for long-term use in normal households and is mostly used for short-term water pipe use; The PPR live ball valve is the most suitable for household use at present. There are also two materials, copper and stainless steel, and there is no significant difference between the two materials, which can be chosen freely. The recommended price is between 75 en 150 yuan. As long as it meets this standard and belongs to a big brand, it can be suitable for household use.
