1 Refer to the
VF Series High-Pressure, High-Temperature Butterfly Valves
Product Bulletin (LIT-977208) for actuator
specifications.
2 Types V and Z valves are
rated for 150 psig (1,034 kPa) saturated steam at 366°F (186°C)
for two-position applications, and 50 psig (345 kPa) saturated
steam at 297°F (147°C) for modulating applications. Refer to the
VF Series High-Pressure, High-Temperature Butterfly
Valves for Steam Service Application Note (LIT-977321)
for more information.
3 For 18 in. or larger ANSI
Class 150 valves and 16 in. or larger ANSI Class 300 valves,
consult the local Johnson Controls®
office.
4 The preferred orientation of
the seat retainer in dead-end service is against the
flange.
5 For pressures between 550 and
740 psig (3,790 and 5,099 kPa), consult the local Johnson
Controls office.
