Viega ProPress ball valve 1/2" x 1/2
This Viega ProPress ball valve is a manual two-way shut-off device designed for potable water lines. Its bronze body and stainless steel full-port ball provide a straight-through flow path with minimal restriction. The lever handle offers direct on-off control without a locking mechanism. It suits residential and light-commercial plumbing installations.
Replaces threaded or soldered 1/2" valves
The ProPress press-fit ends eliminate the need for threading pipe or applying heat with a torch. This speeds up rough-in and retrofit work where open flame is impractical or prohibited. The jump is worth it when labour savings and consistent joint quality outweigh the cost of press tooling. It is not for systems requiring a locking handle or steam service above the rated limits.
Verify 200 psi pressure rating and vacuum tolerance
Confirm the system operating pressure does not exceed 200 psi and that vacuum conditions stay within 29.2 in Hg. Ensure the piping material is compatible with bronze and stainless steel wetted parts. The valve carries no 3-A sanitary rating and is not rated for combustible gas. Buyers needing a locking handle or steam-rated valve should select a different model.

Questions about this item
What pipe diameter does the 1/2" ProPress end fit?
Each end is sized for 1/2" copper tube and presses directly onto it with a ProPress tool — no threading or soldering required
What is the correct pressing sequence to avoid a leak path?
Cut the tube square, deburr inside and out, mark the insertion depth, press once with a calibrated ProPress jaw — pressing twice or rotating the jaw creates a leak path
When should the stainless-steel ball or EPDM seals be inspected or replaced?
Inspect annually for seepage at the press joint or stiff lever operation; replace the valve if the 200 psi rating can no longer be held or vacuum drops below 29.2 in Hg
