LPS Series Heavy-Duty Actuators FCD LFENIM0001-02-AQ – 5/15
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.
aWARNING: 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.
aWARNING: 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.
aWARNING: 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.

1.5 Other Requirements for In-plant Installation
• Pipelines must be correctly aligned to ensure that the valve is not fitted under tension.
• If not expressly agreed, fire protection is not supplied along with the acuator and it must be provided by the user.
1.6 Spare Parts
Use only Flowserve brand original spare parts. Flowserve cannot accept responsibility for any damages that occur from using spare parts or fastening materials from other manufacturers. If Flowserve products (especially sealing materials) have been in storage for long periods, check these for corrosion or deterioration before using these products. A table with the list of the main spare parts for standard ON/OFF applications with the interval times can be found in Paragraph 4.5 at Table 1.
1.7 Service/Repair
To avoid injury to personnel or damage to products, safety terms must be strictly adhered to. Modifying this product, substituting non-factory parts, or using maintenance procedures other than as outlined in this instruction could drastically affect performance and be hazardous to personnel and equipment, and may void existing warranties.
Between actuator and valve there are moving parts. To avoid injury, Flowserve provides pinch-point-protection in the form of cover plates, especially where side-mounted positioners are fitted. These protections are according to Machine Directive 2006/42/EC recommendations. If these plates are removed for inspection, service or repair special attention is required. After completing work the cover plates must be refitted.
In addition to the operating instructions and the obligatory accident prevention directives valid in the country of use, all recognized regulations for safety and good engineering practices must be followed.
aWARNING: Before products are returned to Flowserve for repair or service, Flowserve must be provided with a certificate which confirms that the product has been decontaminated and is clean. Flowserve will not accept deliveries if a certificate has not been provided (a form can be obtained from Flowserve).
1.8 Actuator Lifting and Handling
Only Allen wrenches and hexagonal wrenches of the few sizes are required for the overall operations. The lifting equipment consists on commercial chains and slings of adequate dimensions.
In order to prevent damage to actuator accessories, before starting the lifting operations, ensure that the lifting tools, like chain and clevis hook, are in the correct position and don’t interfere with the control panel and related tubing.
aCAUTION: Lifting and handling of the actuator should be done by qualified personnel and in compliance with the laws and regulations in force.
aWARNING: The lifting lugs or eyebolts are appropriate for actuator lifting only. They are not designed to support the combined weight of the valve and actuator assembly together. During the lifting operations do not stand under the actuator. The actuator should be handled with appropriate lifting equipment. The weight of the actuator is reported on the packing slip and on the overall-dimensions drawing furnished with the documents accompanying the actuator.
For actuator weight, please, refer to Figure 29 in the Annex section. For the general actuator dimensions please refer to LPS technical bulletin LFENTB0001, available on www.flowserve.com.

1.9 Storage
In many cases Flowserve products are manufactured from stainless steel. Products not manufactured from stainless steel are typically provided with an epoxy resin coating or with other painting systems as agreed with the customer. This means that Flowserve products are well protected from corrosion. Nevertheless, in order to maintain good working conditions and a good finish, until the actuator is installed in the plant, it is necessary to follow a few rules during the storage period:
1.9.1Flowserve products must be stored adequately in a clean, dry environment.
1.9.2Ensure that plastic caps are fitted to protect the pneumatic connections and the cable entries, to prevent the ingress of foreign materials. These caps should not be removed until the product is actually mounted into the system.
1.9.3If the storage is outdoors, or if long-term storage is necessary (more than four months), the plastic protection plugs must be replaced with metal plugs, because the plastic plugs are not weatherproof, whereas the metal ones guarantee weatherproof protection.
1.9.4The actuator must be placed on a wooden pallet, in order to not damage the coupling base and avoid the other surfaces resting on the ground.
In case of long-term storage (more than four months), additionally perform the following measures:
a.Coat the coupling parts (spool piece base, flanges, bushings, joints) with protective oil or grease.
b.If possible, blank off the spool piece base flange with a protection disk.
c.Provide a tarpaulin cover or some other means of protection, especially if the storage is outdoors.
d.It is important to periodically operate the actuator with filtered, dehydrated and lubricated air while in storage.
