Pneumatic ball valve manufacturers production requirements

Pneumatic ball valve is a commonly used control valve with the advantages of fast switching, good sealing, small flow resistance, etc. It is widely used in petroleum, chemical, aviation, aerospace and other industries. In order to ensure the quality and use of pneumatic ball valves, pneumatic ball valve manufacturers need to meet certain requirements in the production process.

First, the material requirements

Pneumatic ball valve materials should comply with national standards. Ball, seat, bearing end caps and other parts should be high-strength, corrosion-resistant alloy materials, such as stainless steel, carbon steel, cast steel and so on. Sealing materials should be selected according to the characteristics of the medium used, such as fluoroelastomer, polytetrafluoroethylene and so on. The use of high-quality materials can ensure the service life and safety of pneumatic ball valves.

Second, process requirements

Pneumatic ball valves should be manufactured in accordance with the relevant process requirements. Ball, stem and other parts of the machining accuracy should meet the national standards, such as the ball surface should reach Ra1.6. sealing surface should be ordinary turning, grinding and fine drilling process to ensure sealing performance. The surface of the valve should be treated with persimmon acid degreasing, sand blasting and cleaning to ensure a clean and smooth surface.

Third, the test requirements

The test of pneumatic ball valves should be in accordance with relevant standards, such as GB/T13927-92 standard. The testing process should be carried out in strict accordance with the program, and the test data should be accurate and reliable. The test includes sealing, torque, pressure resistance test and so on. The product can be shipped only after passing the test.

Fourth, packaging requirements

Pneumatic ball valves should be packaged before leaving the factory to ensure that they are not damaged during transportation and use. Packaging should be in line with relevant standards, such as GB/T20081-2006 standard. Packaging should use appropriate materials and methods, including wooden boxes, cartons and foam, etc., to ensure the safety of the valve in transportation and storage.

V. After-sales service requirements

Pneumatic ball valve manufacturers should provide high-quality after-sales service, including technical advice, installation guidance, maintenance and so on. In the use of the valve in the process of problems, manufacturers should respond positively and provide timely service. And provide customers with comprehensive after-sales protection to meet customer needs.

In summary, pneumatic ball valve manufacturers should meet the requirements of materials, process, testing, packaging and after-sales service in the production process to ensure the reliable quality of pneumatic ball valves from the factory. Pneumatic ball valve manufacturers need to continuously explore new technologies and processes to improve the performance and efficiency of pneumatic ball valves to meet the growing market demand.
