Product Overview
The American Granby CVNL150BS is a 1-1/2 in. spring check valve for compatible well pump, pressure tank, and water-system installations. It is used where liquid should continue through the line in one direction while reverse movement is restricted after a pump cycle ends or system pressure changes. The spring-assisted closing action can help maintain the intended piping operation and reduce backward flow through connected equipment.
This model combines a rough no-lead brass body with stainless steel spring, washer, and locknut components and a Buna-N O-ring. Its 200 PSI pressure rating supports use within the stated system limits. Because correct performance depends on proper sizing and orientation, confirm the connection requirements, operating pressure, media, and flow arrow before installation.
