The Hualinkena PFA diaphragm valve process mainly includes the following steps:

1. Material selection: According to customer demand and working condition requirements, select PFA materials with corrosion resistance, high temperature resistance and wear resistance as the main material of valve body and diaphragm.

2. Valve design: according to the actual working conditions, the valve structure and flow channel design, determine the specification and size of the valve.

3. Diaphragm making: advanced processing equipment and technology are adopted to process the diaphragm with uniform thickness and smooth surface on the PFA material to ensure that it has good sealing performance.

4. Assembly and debugging: Assemble and debug all parts of the PFA diaphragm valve to ensure its stable and reliable working performance.

5. Quality inspection: Conduct strict quality inspection on each PFA diaphragm valve to ensure that it meets customer requirements and relevant standards.

6. Packaging and transportation: According to customer needs, the appropriate packaging and transportation methods are adopted to ensure that the products are not damaged during transportation and delivered to customers on time.

When selecting a PFA diaphragm valve, the following factors should be considered:

1. Flow characteristics: Select the PFA diaphragm valve with appropriate flow characteristics according to the fluid characteristics and flow requirements used. For example, for cases requiring regulated fluid flow, a PFA diaphragm valve with regulatory function can be selected.

2. Unbalanced force: When selecting PFA diaphragm valve, consider the influence of unbalanced force on the valve performance. The magnitude of the unbalanced force depends on the shape and structure of the core and seat, as well as the nature and flow of the fluid.

3. Wear resistance: when the fluid contains a high concentration of wear substances, the joint surface of the valve core and the valve seat will be subject to severe friction. To ensure proper operation and service life of valves, PFA diaphragm valves with smooth flow and hard internal material shall be selected.

4. Corrosion resistance: because the fluid may be corrosive, in order to ensure the function and stability of the valve, the relatively simple PFA diaphragm valve should be selected to reduce the damage of the fluid to the valve.

5. Temperature and pressure of the medium: when the temperature and pressure of the medium is high and the change is large, the PFA diaphragm valve with the spool and valve seat less affected by the temperature and pressure change should be selected.

6. Flash and cavitation: In the actual production process, flash and cavitation phenomenon may affect the calculation of the flow coefficient, and produce vibration and noise, and shorten the service life of the valve. To avoid these problems, PFA diaphragm valves that prevent flash and cavitation should be selected.

7. Manufacturers: When choosing PFA diaphragm valve, we should consider choosing a regular large and professional manufacturer to ensure the quality of the valve and after-sales service.
