Description
Barberi® ball shut-off drain valves are used to fill or drain the systems. They are normally used in heating systems, heat generators (wall-mounted boilers, solid fuel generators, heat pumps). The valve is equipped with a plug that, when unscrewed, becomes a knob to open or close the control stem. The control stem of the ball shut-off valve features also an anti-tamper function. By using a screwdriver is indeed possible to position and block the stem in a static position (ball shut-off valve open or closed) to avoid manual or accidental manoeuvres.
