Welding
Only the models that have connections designed for welding (ETO)
should be welded. Valves with clamp connections must not be
welded to avoid damages to the soft parts.
A1 Sanitary clamp
A2 Extended tube ends / ETO
The size, end connections and certification requirements must be
specified at the time of order placement.
Example: 1 off Spirax Sarco 4" M80iV ISO sanitary ball valve
complete with, sanitary clamp (ASME BPE) end connections,
