When the A/B piping port is facing toward you, the D side is on your left.
The wiring of the standard specification manifold is for double solenoids (double wiring specification), and the output number is assigned from the A side to the B side. If single valves are being used, the B side output will be empty.
The ZH□B series (box type) was discontinued in August 2020.
The new ZH□B□A series is compact and lightweight, and the mounting variations have been expanded. For metric sizes, the mounting thread size and pitch are interchangeable.
For AC-A/AC-B/AC-D series modular F.R.L. units, the regulator is from the AR-A/AR-B/AR-D series.
For the part number of the round pressure gauge, refer to the AR-A/AR-B/AR-D series catalog. The modular F.R.L. unit catalog can be found here.
