In the pipeline industry, pneumatic butterfly valve is the most familiar but not a device system. How does the quality of the product determine the quality of the project? What requirements does a good quality pneumatic valve meet and how to test its performance?

In order to ensure the quality of products, the manufacturer should first carry out authoritative testing on the performance of the products when producing the type and specification valves required by the project.

Product quality inspection:

Valve Flow Resistance Coefficient Detection: Valves to enter the pipeline for water delivery. The opening and closing moment of the valve only keeps the valve under normal working pressure to ensure that the opening and closing times of the valve are normal, tight and continuous when closing.

Pre-factory inspection:

Internal pressure testing should be carried out when the pneumatic valve is open and running, testing whether the valve body can withstand the working pressure from the valve 2 times. Whether the valve can withstand 1.1 times of the working pressure from both sides when it is in closed operation to ensure that the valve is well sealed and leak-free.
