1. The pressure/temperature limits in this manual and any applicable standard or code limitation for valve should not be exceeded.
2.Usethisvaluetodeterminethemaximumtorqueoutputallowed.
3. Volume when the diaphragm is in the up position.
4. Includes clearance volume.
5. NBR (nitrile) O-rings are used in the optional top-mounted handwheel and in the optional up travel stop assembly.
6. For higher temperature ratings, contact your Emerson Process Management sales office.
7. This maximum casing pressure is not to be used for normal operating pressure. Its purpose is to allow for typical regulator supply settings and/or relief valve tolerances.
Do not install, operate, or maintain a 1051 or 1052 actuator without being fully trained and qualified in valve, actuator,
and accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is important
to carefully read, understand, and follow all the contents of this manual, including all safety cautions and warnings. If
you have any questions about these instructions, contact your Emerson Process Management sales office before
proceeding.
Description
1051 and 1052 Size 33 spring-and-diaphragm actuators are used on rotary-shaft valve bodies for throttling or on-off
applications. The 1051 may be used for on-off service without a positioner or for throttling service with a positioner.
