ProPress ball valve 79923 for potable water

The Viega ProPress ball valve 79923 is a 1/2 in nominal size two-piece bronze valve designed for potable water systems. Its full-port stainless steel ball and lever handle with locking feature suit residential and light commercial plumbing installations. The valve carries a 200 psi maximum operating pressure rating and a 29.2 in Hg vacuum service rating. It is supplied new and ready for press connection.

Press installation and common issues

Installation uses the ProPress press-fit system, which eliminates threading or soldering and reduces labour time on site. A properly calibrated press tool and the correct jaw size for 1/2 in tubing are required to form a leak-free joint. The most frequent problems are incomplete press cycles, debris on the sealing surface, or misaligned tubing that prevents the O-ring from seating fully. The locking lever helps prevent accidental operation after installation.

Checks before ordering

Verify that the piping material and diameter match the 1/2 in press-end specification for this valve. Confirm the system pressure does not exceed 200 psi and that the media is compatible with bronze body and stainless steel ball materials. Ensure the installation location allows enough clearance for the press tool and lever handle movement. This valve is not rated for steam or combustible gas service.
