Two-way ball valve for potable water

The Viega 79933 is a manual two-way ball valve with a bronze body and stainless-steel ball designed for potable water systems. It uses a press connection and a full-port design to maintain flow. A locking lever handle prevents accidental operation. The valve is rated for 200 psi maximum operating pressure and 29.2 in Hg vacuum service.

Upgrade from threaded or soldered valves

This valve replaces traditional threaded or soldered bronze ball valves where a press connection speeds installation and reduces leak paths. The jump is worth it when labour savings and a secure mechanical joint outweigh the cost of press tooling. It is not for steam lines, combustible gas piping or systems requiring 3-A sanitary compliance.

Check pipe size and press-tool compatibility

Verify that the existing piping matches the nominal 1 in size required for the press ends. Confirm the press tool and jaw set are approved for the fitting profile used on this valve. Ensure the system pressure and vacuum demands stay within the 200 psi and 29.2 in Hg limits. The valve is not rated for steam or combustible gas applications.

Questions about this item

What pipe size does the 1 in nominal valve fit?

The valve body is sized for 1 in nominal pipe and uses a press connection that requires the matching Viega press tool and jaw for a leak-free joint.

Which step is most often missed when pressing the 79933 valve?

Installers sometimes forget to fully seat the press jaw on the fitting bead before activating the tool, leaving an incomplete crimp that can leak.

What component will need replacement if the stem seal begins to weep?

The two-piece bronze body uses a replaceable stem packing set; swapping that packing restores the seal without removing the valve from the line.
