1.2 General Usage
To prolong actuator life, use only clean, dry pneumatic supply fluids. Lubricated fluids are not required for LPS
actuators. Pay attention to follow positioner and other control prescriptions, regarding supply fluid instrument air.
The LPS actuator standard ambient temperature range is: -29°C to 100°C (-20°F to 212°F). Low temperature -60°C
(-76°F) and High temperature 160°C (320°F) ranges (polar, cold, arid and tropical temperature requirements in
accordance with IEC 60721) are available with different materials of construction. In any case, please refer to the
temperature range located in the actuator nameplate.
NOTE: For PED certified applications the standard operating temperature range is -20°C to 100°C (-4°F to 212°F). For
lower temperature applications the range can be extended to -40°C to +100°C (-40°F to 212°F) or -50°C to +100°C
(-58°F to 212°F) with different materials of construction. In any case, please refer to the temperature range located in
the actuator nameplate.
It is the end user’s responsibility to guarantee that the ambient temperature is in according with the actuator nameplate
indications.
a WARNING: It is recommended not to exceed the minimum and maximum allowable temperatures indicated
on the actuator nameplate. More factors like the valve and pipe temperatures, sun direct exposure and other
environmental conditions shall be considered, not to exceed the temperature range.
a WARNING: It is recommended not to exceed the allowable pressure range of the supply fluids, as stated in the
actuator nameplate. It is very important to make the standard maintenance at all safety components. In case
of PED certified cylinders the value of design pressure of the cylinder is indicated on, specific and separate
nameplate: it is necessary to verify that the supply line to the actuator does not exceed the design pressure stated
in the cylinder nameplate.
NOTE: The standard supply fluids are instrument air and nitrogen. Different types of fluids may be used only after
Flowserve verification. In case of PED certified cylinders the type of fluid is indicated on the specific nameplate on
the cylinder.
a WARNING: Only use the recommended type of fluid that is indicated on the nameplate (PED cylinders) and/or in
the contract.
NOTE: The supply fluid must be properly filtered. In case of positioner and/or other components installed on the
control panel, take care that the cleanliness, the filtration and the hydration of the supply fluid are in accordance
with the requirements of these accessories indicated on their own maintenance and user manuals.
1.3 Protective Clothing
Flowserve products are often used in dangerous applications (e.g., extremely high pressures, flammable, combustible,
toxic or corrosive media). When performing service, inspection or repair operations, always ensure that the valve and
actuator are depressurized and that the valve has been cleaned and is free from harmful substances. In such cases pay
particular attention to personal protection equipment (protective clothing, gloves, glasses, etc.).
1.4 Qualified Personnel
Only qualified personnel should perform installation, operation or maintenance activities. Qualified personnel are people
who, on account of their training, experience, instruction and their knowledge of relevant standards, specifications,
accident prevention regulations and operating conditions, have been authorized by those responsible for the safety of
the plant to perform the necessary work and who can recognize and avoid possible dangers.
