The Union Insert (UV) valve is the threaded pipe counterpart of the Flange Insert Valve. 

Designed to be inserted into most standard and hammer type 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 when the valve is installed. 

This provides a permanent visual notification that the union contains a check valve. The UV valve can also be used as a low pressure relief valve or vacuum breaker by using the desired spring settings.
