1. • • Also known as one-way valves or check valves. They have elastomeric edges, or lips, shaped in a way that resembles a duck’s bill (hence their name). Designed for unidirectional, forward flow, any reverse pressure results in the lips closing to a seal, blocking backflow. As forward flow resumes, the sealed lips part again.
