What type of valve should be used to add hydrochloric acid drop by drop?
Thread Content
During the production process, 10% hydrochloric acid must be added drop by drop, and the addition rate should not be too fast. What type of valve should be used for pipes with an inner diameter of less than 10 MM? Help me!
I’ve used glass and PVC ones.
Glass won’t do; it’s fragile. Could someone with more experience give some advice?
PP valves, as well as valves lined with PTFE, will work fine.
Polyolefin valves will do. Of course, the temperature cannot be too high.
Non-metallic valves are acceptable for temporary use, but for long-term stable operation, it is recommended to use steel-lined PE or PTFE ball valves
Glass obviously won’t work, because it’s fragile! Polyolefins, PP valves, as well as valves lined with PTFE are all suitable
