The Union Insert Valve is the threaded pipe counterpart of the Flange Insert Valve. Designed for insertion into most standard 45º ground joint unions, it provides the simplest and most economical way to install a check valve in a threaded pipe system.

A check valve may be installed anywhere in the system where there is a union. The valve works equally well in either a horizontal or vertical position with proper spring selection.

Each Union Insert Valve is furnished with a metal tag, which is quickly attached to the union. The tag is attached when the valve is installed and provides a permanent record that the union contains a check valve.
