 Notes Normal (Outdoor) Condenser De-energized application. With the pilot valve de-energized,
high side pressure is prevented from entering the cavity above the piston-seat assembly.
At the same time the upper pilot port is opened to suction pressure. The resulting pressure
differential across the piston moves the piston-seat assembly to close the reclaim (upper)
main port. When the upper pilot port is open, the cavity above the piston is open to
suction. Pump out of the reclaim condenser is controlled by the bleed rate through the
piston. After the reclaim condenser has been pumped out, and the valve continues to
operate in the normal condenser mode, all flow ceases, thus eliminating high to low side
bleed and the resulting capacity loss.

Reclaim (Reheat) Condenser Energized application. When the pilot valve is energized,
high side pressure is permitted to flow thru the lower pilot port. At the same time the
upper pilot port is closed to suction. High side pressure on top of the piston moves the
piston-seat assembly to close the normal condenser port and open the reclaim (upper)
main port. With the upper pilot port closed there is no high to low side bleed loss with
the system operating in the reclaim mode.
