 Notes The ORI head pressure control valve is an inlet pressure regulating valve and responds
to changes in condensing pressure only. The valve designation stands for on Rise of
Inlet pressure. As shown in Figure 5, the outlet pressure is exerted on the underside of
the bellows and on top of the seat disc. Since the effective area of the bellows is equal
to the area of the port, the outlet pressure is cancelled and the inlet pressure acting
on the bottom of the seat disc opposes the adjusting spring force. These two forces
are the operating forces of the ORI. When the outdoor ambient temperature
changes, the ORI opens or closes in response to the change in condensing pressure.
An increase in inlet pressure above the valve setting tends to open the valve. If the
ambient temperature drops, the condenser capacity is increased and the condensing
pressure falls, causing the ORI to modulate toward the closed position. The ORI valve
is used in conjunction with the ORD valve.
