HEAT RECLAIM
A 3-Way Heat Reclaim Valve directs the refrigerant to
either the Condenser or a Heat Reclaim Coil. When
the solenoid is de-energized, the valve directs the
refrigerant to the condenser.
The pilot valve, a check valve, is directional. When
the solenoid is de-energized the high pressure inlet is
stopped and the passage between suction and valve
chamber is open. When the solenoid is energized the
suction outlet is stopped and the passage between
high pressure and the valve chamber is open.
"B" version of the valve has a bleed port through
the drive piston to the suction manifold. The bleed
port provides a vent for fluids trapped in the Heat
Reclaim circuits during normal operation.
