MODULAR VALVE CIRCUITS

Use of Shuttle Valves
The R-603 is a three input shuttle valve sometimes called a three input “OR”. Actuation of V-1 or V-2 or V-3 will give an output at
port 6, of V-4, and extend C-1.

Two-Hand, No-Tie-Down
This circuit provides an output signal to power or pilot a piece of machinery when two push buttons are manually pressed simultaneously.
Neither button can be tied down. The output will cease if either button is released. See CM-023 in the Pneumatic Circuit Board
section for more details.
