What is the difference between the VAG A11N and the VAG TERRA® M1 drilling saddle (for steel pipes) and the A52K and TERRA K3 (for PVC pipes)?
All of the drilling saddles are comparable in terms of their area of application. The VAG TERRA® programme is the latest range of next generation products and has an integrated auxiliary ball shutoff. The VAG A11N and VAG A52K’s drilling saddle’s auxiliary shutoff must be created with a laterally connected eccentric auxiliary valve. This auxiliary valve must be fitted and removed before and after each drilling.
