| 1. A circuit comprising:
a first valve coupled to a fluid line;
a second valve coupled to the fluid line; and
a supplemental line coupled to the fluid line downstream of the first valve and upstream of the second valve and the second
valve coupled to the fluid line in series with the first valve and in parallel with the supplemental line to provide fluid
flow to a supplemental circuit in parallel with the second valve and the fluid line downstream of the second valve being coupled
to the supplemental line or circuit in parallel with a drain line or tank to provide fluid flow to the supplemental circuit
downstream of the second valve.
