Fluorine lined ball valve FAQ answers



Fluorine lined ball valve is a kind of more common ball valve, mainly in the pipeline of corrosion resistant media play a role in opening and closing, but in the purchase or use, customers will encounter some more difficult problems, listed below several fluorine lined ball valve related problems.

1. What is fluorine lined ball valve, what is fluorine lined ball valve?

A: Fluorine lined ball valve has a common ball valve movement structure principle (with a round through hole ball as the opening and closing parts, the ball with the stem around the center line of the valve body rotation to realize the valve open and close), used to control a variety of strong corrosive media. Fluorine lined ball valve, first of all, "fluorine lined" refers to "fluorine plastic, ptfe" material, fluorine lined ball valve is in the ball valve and fluid contact interface coated with this material of anticorrosion ball valve.

2 lining fluorine ball valve lining material in "PTFE" and "PFA" that is a bit better, a bit more expensive?

Answer: PTFE and PFA are essentially fluorinated plastics, "PTEF" is polytetrafluoroethylene, "PFA" is a copolymer of tetrafluoroethylene and perfluoroxyethylene ether (good solubility). There is no big difference in performance, but PTFE is much higher than PFA in processing temperature and use temperature. In terms of price, "PFA" is a little more expensive.

3. What is the difference between tetrafluoro-lined ball valve and fluorine lined ball valve?

Answer: four fluorine ball valve and fluorine lining ball valve is no difference, but fluorine lining is a general term, and four fluorine indicated which kind of fluorine. It should be said that tetrafluoride is one of the fluorine lining. But tetrafluorin (F4) should be one of the best fluorine at present. The temperature can reach 180 degrees. The F46 is 150 degrees.

4. What internal components does fluorine lined ball valve have?

Spool type: ball spool

Spool material: 2Cr13 lining F46

Flow characteristics: approximately equal percentage

Rated stroke: full open 90°

5 fluorine lined ball valve cleaning should be how to maintain?

A: The decomposed individual parts can be washed by immersion. Metal parts that remain undecomposed non-metallic parts can be cleaned with a clean and fine silk cloth impregnated with cleaning agent (to avoid fiber shedding and sticking to the parts). When cleaning, remove all grease, dirt, glue, dust and so on that adhere to the wall.
