What determines which metering device is active?
What will be an ideal response?
The active metering device is determined by the internal check valve inside the metering device. When liquid flows from the liquid line into the metering device, the check valve closes, and the metering device becomes active. When liquid flows from the coil out of the metering device, the check valve opens allowing full, unrestricted flow.
