Product Overview
The American Granby CVNL125BS is a 1-1/4 in. spring check valve for compatible well, pump, pressure tank, and plumbing systems that need flow to move in one intended direction. Its spring-loaded internal assembly responds as pressure changes, closing when forward flow stops to help reduce reverse movement through the line. This makes the valve useful in pump discharge piping, pressure-system service, and replacement work where a threaded brass check valve is required.
The rough no-lead brass body is paired with stainless steel spring, washer, and locknut components plus a Buna-N O-ring. Female pipe-thread ends support connection to matching threaded piping, while the 200 PSI rating provides a clear selection limit. Verify media, pressure, thread size, and installation direction before ordering.
