Moog Information
Important Information for the
Moog
Servo-Proportional Valve If you
are a user of Moog, Atchley, or Pegasus servo and
proportional valves it is important that you
understand our repair policy. For a number of years
Moog sold its parts to independent servo repair
houses. There are number of those organizations
around the country with varying degrees of
expertise. Since there is no formal benchmark or
requirements to be a “servo repair shop” the repair
of Moog product was not handled in a manner that was
conducive to Moog’s outstanding reputation in the
field. These houses do not have the technical
performance specification documents required to test
the finished repair, therefore it is impossible for
a valve to be “brought up to specs” without this
information. In addition, a number of these houses
do not have the expertise or Moog training to repair
our valves or the correct test facilities. If an
independent repair house is repairing your Moog,
Atchley or Pegasus product he is using either
surplus or aftermarket parts. Moog no longer sells
genuine parts to anyone for repair. As a result they
offer one of the best factory repair services in the
world. Every valve that is sent to
the Moog factory for repair carries a 2 year
warranty (same as new). The repair is normally
turned around in 3-5 days and expedited breakdown
next day delivery is possible. Every repair is
documented and a historical pedigree is developed so
a new repair can be compared to the prior one. Every
valve has returned with it a full report on the
genuine parts that were replaced and a copy of the
test that was performed on the valve. If there are
recommendations that can be made to correct problems
they will be included on the report.
To return a valve under this program, contact Mark
Needham in our sales department.
Mneedham@flowdynamics.net. (205)581-1224. Mark
will take the required information and facilitate
the repair. Once the information is obtained, Mark
will give you shipping information in order for you
to ship the valve. Moog has three
levels of repair.
Category “A” repair is a
clean and calibrate. This includes complete
disassembly and inspection for wear and
contamination. After reassembly they test,
flush, replace filter and base-o rings then test
to spec.
Category “B” repair begins with
disassembly, and can require a rebuild/replace
torque motor and/or rework bushing spool
assembly, body and spool. Finally the reassemble
to spec as in category “A” repair.
Every valve must be pre-approved for repair to
at least a Category “B”. This is from experience
with the quote and wait process which can add
weeks to the repair procedure. If a valve is not
working in most cases a Category “B” repair will
occur and is the most economical option. Valve
repairs have remained in waiting for months in
anticipation of approvals from customers.
Therefore the Category “B” pre-approval is
required and is the best use of time.
Category “C” repair usually requires
replacement or repair of electronics in addition
to other parts. This category requires customer
approval before proceeding after having been
quoted a firm price for the repair. A customer
may opt for this if the delivery of a new valve
is not acceptable.
When requesting repair from Mark, in
most cases he can give you a rough estimate of what
a category “B” repair will cost. Keep in mind,
approving a Category “B” does not mean you will be
charged for a Category “B”. It is simply a not to
exceed procedure without customer approval.
There have been a number of misconceptions about
Moog not selling parts for their valves and
erroneous information being distributed in order to
replace our valves with other brands. This decision
was not made lightly, but with your our customers in
mind. Factory repaired equipment with guaranteed
performance and warranty is the best way to insure
that the equipment performs in the manner that you
expect from Moog. Rest assured that this program is
the most reliable and economical way to maintain
your Moog servo and proportional valves. If you have
any questions please feel free to e-mail our
President for clarification on any repair issue.
