There are many factors that affect the price of air valves, such as market conditions, brand, 등. 하지만, if we only consider the product itself and exclude external factors, even if two air valves have exactly the same design, 크기, and appearance, the two main factors that determine their price differences are still material and function.
Taking our air valves as an example, there are two material options: nylon and polypropylene (PP). In terms of function, they are divided into two types: combination type(Triple Effect Air Valve) and kinetic type(Double Effect Air Valve). 다음, I will explain the differences between them in terms of material and function, and how these differences affect the price of air valves.
Material of Air Valves
Our air valves are mainly available in two materials: nylon (PA) 그리고 폴리프로필렌 (PP). Although air valves made of these two materials may look exactly the same in appearance and structure, their mechanical strength and pressure resistance are different.
Nylon is stronger and more durable, and its pressure rating can reach PN16 (16 술집). PP is relatively weaker, with a pressure rating generally up to PN10 (10 술집). 그러므로, air valves made of nylon are usually more expensive.
그래서, which material should you choose? We generally recommend that customers choose nylon. 이는 다음과 같습니다., in an irrigation system, although the working pressure of the end irrigation equipment may not be very high, the main pipeline usually needs to withstand higher water pressure. Air valves are generally installed on the main pipeline. 그러므로, choosing nylon, which has better pressure resistance, is a safer option in actual use.
게다가, buyers should pay more attention to some air valves on the market that are sold at significantly lower prices. Such low prices may mean that the manufacturer has reduced costs by using lower-quality raw materials, thinner material, or making compromises in the product structure. When purchasing, don’t focus only on appearance and price. You should also check the actual material and pressure rating of the product.
Functions of Air Valves
Air valves can be divided into two types according to their functions: Triple Effect Air Valves（dynamic type） and Double Effect Air Valves（combination type）. The functional differences between them are mainly determined by their internal structures, specifically the differences in their valve floats. 아래에, we provide a disassembled comparison image of the two types of air valves. As you can clearly see, although they look exactly the same from the outside, their internal valve floats are different. This is also the main reason for the differences in their functions and prices.
The Triple Effect Air Valve is more sensitive to air inside the pipeline. When air accumulates inside the pipeline, it can release the air in time. Even when only a small amount of air enters the pipeline, it can continue to release it. In comparison, the Double Effect Air Valve is less sensitive to air. It needs to wait until the accumulated air inside the pipeline reaches a certain amount before starting to release it.
그래서, what do Double Effect and Triple Effect mean? Simply put, Double Effect refers to air intake and air release, while Triple Effect adds a controlled air release function. As shown in the disassembled comparison image, the valve float of the Triple Effect Air Valve on the left has an additional small air release device compared to the Double Effect Air Valve on the right. When there is air inside the pipeline, this small device rises slowly first to gradually release the accumulated air. 이후, the entire valve float rises to further complete the air release process. The Double Effect Air Valve on the right does not have this additional device. It can only release air by lifting the entire valve float.
Since the Triple Effect Air Valve has an additional controlled air release function and is more sensitive to air inside the pipeline, its production cost and selling price are usually higher. This is also the type of air valve we mainly promote.
그러므로, when purchasing air valves, don’t just look at their appearance. Even if two air valves look exactly the same, you should always check their internal structures and actual functions to avoid paying a higher price for a Double Effect Air Valve with relatively simpler functions.
Tips
Air valves can have many different names based on their functions, which can be confusing, especially for people who are not very familiar with these products. Regardless of the names used, there are actually only two types. To sum up:
Combination Air Valve = Three Function Air Valve = Triple Effect Air Valve
Kinetic Air Valve = Two Function Air Valve = Double Effect Air Valve
지금, when you come across these names, you won’t get confused anymore!
결론
요약하면, material and function are the two main factors that affect the price of air valves. When purchasing air valves, you should first pay attention to whether the product is made of PA (nylon), as this directly affects the strength and durability of the air valve. 둘째, you should check whether it is a Triple Effect Air Valve or a Double Effect Air Valve, as this directly affects its air release performance. Don’t judge an air valve only by its appearance or price. Understanding its actual material and functions will help you make a better purchasing decision.
