6.2.4 Severe Duty
This is defined as open/close service when run loads exceed 30% of the unit rating. This also includes
all modulating applications.
NOTE: Oil should be changed every 3000 seats for open/close service, or sooner if the oil has been
contaminated.
The spares suggested for severe duty are identical to the long-term duty spares.
6.3 Other Concerns
There are other unique application requirements that may result in additional parts being added to the
list of recommended spares. Some additional issues or requirements that should be considered when
determining required spare parts include (but are not limited to):
1. Maintenance program
2. Frequency of operation
3. Modulating duty
4. Frequent operation by handwheel
5. Regular testing
6. Stall/overload condition
Flowserve strongly recommends using OEM parts to support and maintain your MX actuator. Installing
parts other than genuine Flowserve Limitorque parts could cause premature failure of your actuator and
voids any remaining warranty.
The above guidelines are provided to assist you in determining your unique spare parts needs. Please
contact your local Limitorque Sales Office or local Authorized Stocking Distributor for additional help in
evaluating your needs.
