Name and function of the area marked with a circle on the valve

This post was last edited by gao*ang0217 on 2017-9-3 22:04. The names and functions of the areas marked with circles on the valves are indicated; a rough diagram of all the air pathways is provided. It’s not clear what the specific attachments are, so refer to the actual product images. This is why, when a positioner is used for the valve, there are two pneumatic amplifier circuits, and one of these circuits also has a bypass
Could someone explain how this valve works, and how the air flow takes place?
@Waneng, help me take a look at this
@jxhaio0 @chenhs @gasturbine
Could everyone help take a look and explain this?
What do the table notes \"time open\" and \"time close\" mean?
Behind this valve positioner, there are two separate paths leading to the cylinders; the path that leads to one cylinder has an additional bypass compared to the other path. There are two additional black valves marked as 1.2. Why is it designed this way
One of them might be a hold-back valve; as for the other two, I think there are also 2 solenoid valves – could those be control valves for the SIS system? !
There are no two solenoids; there is only one to control the air circuit
It is recommended to draw a detailed diagram of the gas circuit for analysis in order to gain a clearer understanding
