We deal in water-based paints, and a constant flow rate is required when adding monomers. Do you have any constant-flow valves?
Regulating valves serve this purpose: to regulate flow rate

Dude, your question actually isn’t about a constant current valve. It is a flow controller ； Theoretically, if all external conditions remain unchanged, any opening degree of any control valve corresponds to only one flow rate. However, when the external conditions change, the flow rate also changes; for example, if the process is based on gravity flow, as dripping continues, the liquid level gradually drops and the flow speed slows down. Therefore, the solution to this problem is 1 automatic control valve + 1 flow meter; through automated control, the reading from the flow meter is compared with the desired flow rate, thereby controlling the opening degree of the control valve and ensuring stable flow. If the dosage added is very small, 1. the selection of the flow meter needs to be considered ； 2. Precision of adjustment ； Wait for the requirements. If you need it, you can send me a private message and I’ll help you get in touch with them for a phone number. (If it’s not my phone, I won’t put it outside.)
Hehe, using a high-precision metering pump + flow meter for monitoring is also an option
This is not a valve issue; a flow-limiting orifice plate can be used for constant current control, or flow-rate customization controls can also be employed
If it’s a constant flow rate, a pump should be used
Hello, Shanghai Jingou has this type of valve, which is designed specifically for such applications. You can add me on QQ at 2885123323 so that I can help you select the right model and provide a quote
