Valve Type and Application

The Legend Valve 450-834P is a 3/4" no-lead DZR forged brass press-by-FNPT union valve designed for potable water plumbing installations. It connects press-fit copper tubing to female NPT threads in residential or light commercial systems. The union end allows straightforward disassembly for maintenance or fixture replacement without cutting pipe.

Connection Constraints

This valve joins a press connection on one side to an FNPT thread on the other, so both joint types must be compatible with the piping material and system pressure. The press end requires a calibrated press tool and approved jaws for a watertight seal. The FNPT side demands proper thread sealant and engagement depth to prevent leaks. California Proposition 65 warnings indicate the presence of chemicals linked to cancer and reproductive harm.

Installation Verification

Confirm that the piping system uses 3/4" copper tubing approved for press fittings and that the mating component has a matching 3/4" male NPT thread. Verify that the press tool and jaw set are rated for this valve size and DZR brass body. Ensure local codes permit press-to-thread transitions in the intended application and that installers follow the manufacturer's press procedure for a secure joint.
