Process Conditions
Process temperature range Œ
Steam applications:
-20° to +500° F (-29° to +260° C)
Non-steam applications:
-20° to +600° F (-29° to +315° C) 
Process pressure range
5100 psig @ +100° F
(351 bar @ +38° C)
Œ Maximum process temperatures are based on ambient temperatures less than or equal to +120° F (+49° C).
Higher ambient temperatures require reduced process temperatures.
 Consult factory for low temperature applications down to -330° F (-200° C).
