What is this?

What role does this play in the pneumatic circuit diagram? The air supply on the right side comes in through a pressure reducing valve; it is connected to the positioner above, and goes directly to the cylinder below
Power air enters the cylinder; the positioner outputs a signal to control the opening degree of the pneumatic amplifier, thereby regulating the amount of power air supplied to the cylinder
Ah! Go and watch my short video on that topic; my first video is one that breaks down this thing, and you’ll understand it as soon as you watch it
It seems to be a retention valve, also known as a locking valve……

The third floor answer is correct; this device is called a booster, or pneumatic speed increaser, and it is generally used in actuators with large cylinders or diaphragms. This is commonly used on cut-off valves, connecting to solenoid valves; in the original post, it was connected to a positioner? It’s uncommon to do this.
