It’s a fluorocarbon-lined ball valve used for heating titanium dioxide slurry; everyone, please analyze the reasons and suggest some alternative solutions! The medium conditions for fluorine-lined valves should not contain hard particles, crystals, impurities, etc., to prevent wear of the fluorine lining on the valve core, seat, or PTFE bellows during opening and closing operations. For media containing hard particles, crystals, or impurities, ceramic linings can be used for the valve core and valve seat when selecting components, from the Haichuan Pump and Valve series
Crystallization causes wear on the ball and seal ring, resulting in poor valve sealing. It is recommended to use fluorine-lined insulated ball valves.
To what temperature should it be heated? Path and pressure parameters, let’s hear about them
In such cases, our company’s coaxial valves are quite suitable. These valves can handle media in gaseous, liquid, gelatinous, or granular states, and they can maintain a sufficient service life even when the media is mud or abrasives. For similar process conditions involving media with granular or powdery solids, if the temperature level is not increased, coaxial valves remain the more suitable choice. If you're interested, you can send me a private message or check out this post: http://bbs.hcbbs.com/thread-1320253-1-1.html
Crystallization causes wear on the balls and seals
It’s unbearable to gamble with a sphere that has been worn away by erosion. The correct operating conditions determine the right selection. When faced with a problem, solve it. Learned* it

The medium is an acid-containing slurry, which is quite troublesome
Using a hard-sealed ball valve can solve this issue
The slurry contains crystalline particles, and its hardness is greater than that of the rubber lining. Suggestions for solutions: 1. If the pressure is not high, could a ceramic lining be used? 2. If the process conditions permit, could a metal ball valve be employed?
It’s not worth taking the risk of having the sphere worn away by erosion; I’ve learned that too – when there are corrosive substances present, it’s necessary to use corrosion-resistant seals
