The valve has ends for welding as standard.
Weld carefully/aim at stressless welding to avoid deformation on sealing areas.
Check the valve for smooth operation after welding.

Dismantle the valve in accordance with the description of dismantling the valve, see 5.2 Dismantling of valve
Step 3
Before welding the valve into the pipe line please note:
1. Maintain the minimum clearances "A" so that the actuator with
the internal valve parts can be removed - please see later on
in this section!
If there is a risk of foot damage, Alfa Laval recommends leaving
a distance of 120 mm (4.7”) below the valve (look at the specific
built-in conditions).
