In exemplary embodiments, a bi-directional valve for a bi-flow filter drier includes a valve body and a movable valve member disposed within the valve body. The movable valve member is movable within the valve body between a first position and a second position. In the first position, the movable valve member permits fluid flow in a first or forward flow direction through the valve while blocking or inhibiting fluid flow in a second or reverse flow direction through the valve. In the second position, the movable flow member permits fluid flow in the second or reverse flow direction through the valve while blocking or inhibiting fluid flow in the first or forward flow direction through the valve. The direction of fluid flow through the other filter drier components may be essentially the same whether the movable valve member is in the first position or the second position.

A thermostatic expansion valve includes an operating rod, a recessed receiver portion, and a first metering pin positioned at least partially within the receiver portion to selectively contact the operating rod. The first metering pin includes a base diameter, an overall length, and a taper portion. The taper portion is tapered at a specified degree relative to a longitudinal axis of the first metering pin. The thermostatic expansion valve is adapted to operate at a first specified refrigeration tonnage when the first metering pin is positioned at least partially within the receiver portion, and to operate at a second specified refrigeration tonnage when the first metering pin is replaced with a second metering pin including a different taper portion than the first metering pin.
