Arrow on Pneumatics regulator


#1

The tubing coming out of the port with the arrow is the low pressure side or high pressure?


#2

Yes.


#3

The arrow points to the low pressure side, high pressure enters where the arrow originates, it signifies the flow from high to low


#4

^^ This. The high-pressure input is the port across from the arrow. The regulated outputs are the port with the arrow, and the ones on either side of it.
