What are the key performance indicators of dispensing valves in fluid control?

In modern industrial manufacturing, dispensing valves are important components in the field of fluid control, and their performance is directly related to product quality and production efficiency. Whether it is the precision assembly of electronic products, the packaging of semiconductor devices, or the sealing process in automobile manufacturing, dispensing valves play an indispensable role. Therefore, a deep understanding of the key performance indicators of dispensing valves in fluid control is of great significance to improving the stability of production lines and product quality.

Flow accuracy
Flow accuracy is one of the primary indicators for measuring the performance of dispensing valves. It refers to the degree of deviation between the actual output flow and the theoretical set flow under the set conditions of the dispensing valve. Dispensing valves with high flow accuracy can ensure that the amount of glue dispensed each time is accurate, thereby ensuring the consistency and stability of the product. In the field of precision manufacturing, such as semiconductor packaging, a small flow deviation may lead to a decline in product performance or even scrapping, so the importance of flow accuracy is self-evident.

Repeatability
Repeatability is another key performance indicator that reflects the stability of the output flow of the dispensing valve in multiple repeated operations. Excellent repeatability means that no matter how many times the dispensing operation is performed, the output flow rate can be highly consistent each time. This is crucial for production lines that require a large number of repetitive dispensing operations, and can significantly improve production efficiency and product quality.

Response time
Response time is an important indicator for measuring the dynamic performance of dispensing valves. It refers to the time required from receiving the dispensing instruction to actually starting to output the fluid. On an automated production line, a fast response time can reduce waiting time, improve production rhythm, and thus increase overall production efficiency. Especially in high-speed dispensing operations, the length of the response time often becomes a key factor restricting production speed.

Sealing performance
Sealing performance is directly related to the leakage problem of the dispensing valve. Excellent sealing performance can ensure that the dispensing valve can still maintain a stable sealing state and prevent fluid leakage under harsh working conditions such as high pressure, high temperature or corrosive media. Leakage not only leads to material waste and environmental pollution, but may also cause damage to other equipment on the production line and even cause safety accidents. Therefore, sealing performance is a key link that must be strictly controlled during the design and manufacturing process of the dispensing valve.

Durability
Durability refers to the ability of the dispensing valve to maintain its stable performance during long-term use. This includes wear resistance, corrosion resistance, fatigue resistance and other aspects. Excellent durability can extend the service life of the dispensing valve, reduce replacement frequency and maintenance costs. At the same time, it can also improve the stability and reliability of the production line and avoid production interruptions and losses caused by equipment failure.
