A diverting mechanism constructed from polyvinyl chloride (PVC) that uses a spherical closure to control the flow of fluid through three separate ports represents a versatile plumbing component. Rotation of an internal ball with a bore through it dictates which ports are connected, allowing for fluid to be directed to different destinations or to be shut off completely. An example application involves directing water from a single source to either a pool filter or a bypass line, based on operational needs.
These valves offer a cost-effective and durable solution for fluid control, particularly in applications where corrosion resistance is paramount. Their widespread adoption stems from the ease of installation, relatively low maintenance requirements, and ability to withstand various chemicals. Historically, these valves have replaced metallic alternatives in many applications due to the reduced cost and improved resistance to degradation from corrosive substances, contributing to longer service life and reduced operational expenses.
