What is this on the regulating valve? What does it do?
377D locking valve, a regulating valve used to control the reversal of the air path during road closure.
Ok thanks I found the manual!
In layman's terms, it is an air source retaining valve.
The fisher 377 you have is a fisher double-acting valve. It is professionally called a multi-channel pneumatic converter. It may be matched with a positioner or a gas tank to achieve gas distribution or three-short protection functions.
That's quite right. It is difficult to adjust at the beginning of contact
In fact, it is a two-position five-way air control valve
I’ve seen it on the retaining valve and learned from it, thank you guys :)
What I also want to say is that this thing is very unfriendly to friends who come into contact with it for the first time, and it is too difficult to adjust:'(
There are too few photos, and all the pipelines need to be photographed for analysis.
