Seeking help with valve selection

Material temperature: the highest temperature is 110°C, while the lowest temperature is at room temperature; however, sodium sulfate crystallizes in winter, and sodium chloride crystallizes when its concentration is high； pH value: between 10 and 13 ； Solid content is 40%-80% ； Main functions of valves: They are primarily used as control valves; a stop valve is required at the pump inlet. Internal leakage in the valves can cause the material to accumulate and crystallize inside the pump. We are currently using stainless steel ball valves, but after installation and replacement, internal leakage occurs after just a few openings and closings. Could you advise on what material and type of valve should be used in applications similar to salt washing?
It is recommended to try using ceramic valves; metal valves will definitely break down very quickly under such operating conditions
In terms of operating conditions, ordinary valves are not suitable for use; firstly, there is corrosion, and crystallization adds to the problems. Ordinary ball valves are prone to getting stuck due to crystallization; forcing them to rotate will inevitably damage the sealing ring, leading to internal leakage. Our company has experience in selecting suitable models for this purpose, and we have also successfully modified valves under similar operating conditions; the results were quite good. Please contact me so that we can discuss this further!
Could solvent cleaning or heating be added to the valve body?
Okay! Thank you! Let me find out.
