Management of Change
Management of Change (MOC) is a procedure used to proactively manage changes
that have the potential to impact safety or the process within a plant. Evaluating
new techniques for improving MOC approval procedures can have an impact on
plant efciency. Historically, upgrading obsolete products or replacing existing
process control equipment had been delayed or abandoned due to the extensive
paperwork involved in completing a complex MOC approval sheet.
Contained in the following sections are design comparisons between the obsolete
Jordan MV-1020 and VA-1020 electric actuators and the current CML-250 and
CML-750 electric actuators. These comparisons are intended to help end-users
understand the similarities and differences between the Jordan and CML electric
actuators and help facilitate an efcient and safe transition.
Background
Baumann 24000 valve assemblies have transitioned away from Jordan MV and
VA actuators to CML-250 and CML-750 actuators. Jordan MV-1020 and VA-1020
electronic modulating valve actuators featured state-of-the-art stepper motor
technology to provide unrestricted, continuous modulation and exacting position
control. The performance of those actuators rivaled the power of our pneumatic
diaphragm sliding-stem designs.

The CML electric actuator series leverages all of the features end-users have come
to know in the Jordan MV and VA actuators, along with improvements like increased
response time, a shorter and narrower prole, optional power backup, and a local
control option.

instrumentation diagram (P&ID)?
A: No.
Q: Does the proposed modication change process chemistry,
technology, or operating control philosophies?
A: No.
Q: Does the proposed modication change how the existing plant is
operated?
A: No, valve capacity is not affected by actuator revisions.
Q: Does the proposed modication change process ows?
4
A: No, valve capacity is not affected by actuator revisions.

Q: Does the proposed modication change existing pressure relief cases?
5
A: No. This change involves actuators only. Pressure relief valve sizing is
not considered when sizing and selecting Baumann control valves for
end-user applications. If the control valve is determined to affect
upstream or downstream safety relief cases, review by the end-user or
third party is recommended.
Q: Does the proposed modication change the process description?
6
A: No.
Q: Have the codes and standards to which the new equipment was
7
designed changed?
A: Not to our knowledge, but since this is not an original Emerson design,
we can’t conrm if our supplier’s design codes and standards have
changed.

such as a change in material form (cast, forged, or alloy)?
A: No. The actuator housings on both the Jordan and CML models are all
made from cast aluminum.
Q: Does the proposed modication introduce new equipment items that
require periodic predictive maintenance?
A: No. These equipment items will require the same periodic predictive
maintenance as the previous equipment items.
Q: Does the proposed modication change existing operator training
requirements?
Yes. Operating instructions can be found in the CML Series
A:
instruction manual.
Q: Does the proposed modication introduce new equipment items that
require training manuals, maintenance procedures or training to teach
the maintenance department how to maintain them?
Yes. Emerson local business partners and sales ofces offer local
A:
training and support to help ensure operators, maintenance personnel,
and instrument technicians are trained on CML electric actuators. Visit
Fisher.com to nd a representative near you.
Q: Does the proposed modication introduce new equipment items that
12

require spares or obsolete spares for existing equipment?
A: No.
Q: Does the proposed modication permanently remove the spares for
existing pieces of equipment?
A: No.

A: No.
Q: Does the proposed modication require welding work to be performed?
A: No.
Q: Have the materials of construction been reviewed to ensure that the
metallurgy is correct?
A: Yes.
