For a single-acting control valve with a positioner, if rapid spring return is required, should a pneumatic control valve or an electromagnetic valve be used?
Thread Content
For the shut-off valve, I used a gas control valve and a quick-release valve. Achieve rapid air intake and exhaust respectively. Of course, pneumatic control valves can also release air, but they certainly cannot reset as quickly as quick-release valves. But the control valve is not very clear. Are there any specific pneumatic requirements for quick-release valves? It’s still the case that the quick exhaust valve and the positioner don’t work well together. Just as pilot-operated solenoid valves cannot be used with positioners, there is a similar issue. If there are any experts who know the answer or have tried this, please help resolve my doubts
I got the title wrong. Is it a pressure control valve or a quick-release valve? The pneumatic valve must be installed together with the solenoid valve
Based on your description, if a single-acting control valve with rapid spring return is required, using a solenoid valve might be more suitable. The solenoid valve can be opened or closed quickly, allowing the spring to return to its position swiftly. A pneumatic control valve can also achieve a similar effect, but it may not be as fast as a solenoid valve. As for the pneumatic requirements for quick-release valves, the specific requirements may be related to the use of a positioner; it is recommended to consult the manufacturer or professionals for accurate information. .
