A flow control apparatus includes a body, a door, a drip chamber holster, and a valve. The door is pivotally coupled to the body. The drip chamber holster is coupled to one of the body or the door to retain a drip chamber. The valve is disposed within the body and is configured to receive a fluid line coupled to the drip chamber when the door is in an open position. The valve is operatively coupled to the door to secure the fluid line within the valve when the door is in a closed position.
