ARB Pressure Control Airflow

[jeronimo]

Hello guys, I decided to post this here hoping there would be someone who knows the math behind calculating airflow better than me.

To cut the story short I bought into the ARB Pressure Control and while planning on installing it for use with my ARB twin compressor I noticed the tiny input/output holes of the solenoids. Both solenoids have three 2.1mm diameter holes as input and a single 2.1mm diameter hole as output obviously regulating the pressure.

I am planning to use this with a four tire system to inflate and deflate my tires simultaneously, but I am trying to figure out if and how airflow would be affected by the the solenoid input & output.

Any ideas are highly appreciated. Here are some picture of the manifold and its components:

To make the question more clear I am wondering how this ARB Pressure Control manifold and valves would affect inflation and deflation times given previously I would inflate straight off the ARB twin compressor with a four tire system and deflate through the four tire system alone

Hey
I use the same systems as you tagged
Arb Twin Turbo
four tire system kit
The system works fine; there is no need to change anything, just a little slower in filling the air because the system stops for a few seconds to check for pressures.

You can get similar control valves with larger ports on Amazon. Used in pneumatic control systems.

Reviving this; what ever happened? Worth using the Pressure Control system with a four-tire inflation/deflation system? Thanks.

a single 2.1mm hole will flow more (greater than 6 scfm) than the output of the ARB twin at inflation pressures, so its not a restriction there, deflating will restrict to around 4 scfm. more likely that any restriction really comes from any obstruction of those hole from the actual solenoid valve.
