Seek solutions for electromagnetic control valves and proportional valves
Thread Content
The current air pressure inside the reaction chamber is 2–10 kPa (gauge pressure), and the air needs to be exhausted at a rate of 10 LPM. Please suggest suitable proportional valves, solenoid control valves, or other types of control valves for this purpose. I examined the options provided by many companies regarding proportional valves, mass flow controllers, pressure controllers, etc., but none of them were suitable since the differential pressure was only 2 to 10 kPa. Looking for recommended solutions. I’ve been driven crazy by my boss. .
I guess you’ll have to keep going crazy.
A self-acting micro-pressure control valve is selected; this type of valve is used in applications involving low pressures
LPM = liters per minute? I don’t see what’s difficult about that,,, What is the diameter of the exhaust pipe?
I’ve checked, and it seems that it’s not possible to precisely adjust the pressure inside the reaction chamber, right?
Expert, the diameter of the exhaust pipe is 12 mm. Is there a plan? It is necessary to precisely adjust the exhaust rate in order to control the pressure inside the cabin.

No one thinks it’s a big issue; just choose a small-flow single-seat control valve – the valve seat diameter should be around 5-6 mm, with a rated CV value of about 0.08. Since you don’t have any operational data, I’ve just made an estimate. Is there a flow meter?
