ProPress ball valve for potable water

The Viega 79935 is a manual two-way ball valve designed for potable water systems. Its bronze body and stainless-steel ball provide corrosion resistance in residential and light commercial plumbing. The full-port design maintains flow capacity through the 1-1/4 inch connections. Installers seeking a press-compatible shut-off device will find this model suitable.

Verify press tool and tubing compatibility

Confirm that your press tool and jaw set are approved for the ProPress system before ordering. The valve ends accept 1-1/4 inch tubing prepared to the manufacturer's insertion depth and profile. Ensure the piping material is listed as compatible with the ProPress sealing element. No threading or soldering equipment is required for the joint itself.

The valve is rated for a maximum operating pressure of 200 psi in water service. It holds a vacuum service rating of 29.2 in Hg for drainage or suction applications. The non-locking handle allows quick manual operation without a padlock provision. Steam and combustible gas pressures are not rated for this model.
