Installation Instructions
4.1 Safety Precautions
c WARNING: Read this Installation, Operation and Maintenance Manual carefully and completely
before attempting to install, operate, or troubleshoot the Limitorque operator.
c WARNING: Potential HIGH PRESSURE vessel — be aware of high-pressure hazards associated
with the attached valve or other actuated device when installing or performing maintenance
on the operator. Do not remove the operator mounting bolts from the valve or actuated device
unless the valve or device stem is secured or there is no pressure in the line.
c WARNING: For maintenance and/or disassembly of the operator while installed on the valve,
ensure that the operator is not under thrust or torque load. If the valve must be left in service, the
valve stem must be locked in such a way as to prevent any movement of the valve stem.
c WARNING: Do not manually operate the operator with devices other than the installed hand-
wheel. Using force beyond the ratings of the operator and/or using additive force devices such as
cheater bars, wheel wrenches, pipe wrenches, or other devices on the operator handwheel may
cause serious personal injury and/or damage to the operator and valve.
c WARNING: Do not exceed any design limitations or make modifications to this equipment
without first consulting Limitorque.
c WARNING: Use of the product must be suspended any time it fails to operate properly.
a CAUTION: If a motor actuator is driving the manual operator, do not operate the valve under
motor operation without first checking and setting the limit switch setting and checking for
correct motor rotation.
a CAUTION: Do not use replacement parts that are not genuine Flowserve Limitorque parts, as
serious personal injury and/or damage to the operator and valve may result.
