The following question is a very practical issue encountered in the field of engineering – can process engineers solve it? A DN400 double-acting pneumatic valve that can only operate in fully open or fully closed positions. The required air supply pressure is 3-6 kilograms. The problem we are facing at present is that the valve opens and closes too quickly (compared to the user’s requirements). Now, is it possible to reduce the opening and closing actions of the valve? Everyone, please take a look; experienced experts on site are welcome to offer their guidance! The method aims to be simple and practical! This is a project example I saw online; it’s very useful, and I believe those who have spent a lot of time on site will encounter it. The forum is filled with discussions about documents on desks all day long; today, let’s try something different and go to the actual site. Prerequisite: The meter reader isn’t on site; nobody knows where he went to drink, haha.
Double-acting pneumatic valve actuators are generally of the piston-cylinder type; by reducing the pressure of the process air entering the cylinder or by partially blocking the exhaust port, the exhaust speed can be decreased
This is a common issue; reduce the gauge air pressure a bit
