Note 1) * indicates elbow type only.
Note 2) □ indicates the control method (0 for meter out, 1 for meter in).
Note 3) Meter-out type and meter-in type visual differentiation.
Visually differentiated by lock nut. The lock nut on the meter-out type is zinc chromate plated (round-type lock nut is electroless nickel plated), while the meter-in type is black zinc chromate plated.
Note 4) Models marked with ◎ are nickel plated as standard.
