The product must not be used in this region.

High temperature packing required for use on

this region.

Extended cover is required for use in this region

Notes: 1. Where the process fluid temperature is sub-

zero and the ambient temperature is below

+5 °C (+41 °F), the external moving parts of

the valve and actuator must be heat traced to

maintain normal operation.
