11.4.1 Welding isolation valve to pipe

For the Safe-Drive™ Isolation valve, two holes – 50 mm (2") and 25 mm (1") – are
drilled to the pipe and the bridge between the holes is then removed. To help you
place the holes correctly, Vaisala delivers with the valve an installation guide sticker
(see Figure 11.6).
