LPC Compact Actuator Series FCD LFENIM0002-00-AQ 07/14
1.3 Protective Clothing
Flowserve products are often used in problematic applications (e.g. extremely high pressures, dangerous, 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 (protective clothing, gloves, glasses etc.).
1.4 Qualified Personnel
Qualified personnel are people who, on account of their training, experience and 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 General Requirements for In-Plant Installation
• Pipelines must be correctly aligned to ensure that the valve is not fitted under tension.
• Flowserve can provide a fire protection system. If not expressly agreed, fire protection must be provided by user.
1.6 Spare Parts
Use only Flowserve 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 on store for longer periods check these for corrosion or deterioration before using these products.
1.7 Service/Repair
To avoid possible 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 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. Apart from 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.
a WARNING: 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).

LPC Compact Actuator Series FCD LFENIM0002-00-AQ 07/14
1.8 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 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 on the plant, it is necessary to follow a few rules during the
storage period:
• Flowserve products must be stored adequately in a clean, dry environment.
• Ensure 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.
• If the storage is outdoor, or if long-term storage (more than four months) is necessary, the plastic protection plugs
have to be replaced by metal plugs, because the plastic plugs are not weatherproof function, whereas the metal ones
guarantee a weatherproof protection.
• The actuator must be placed on a wooden pallet, in order to not damage the coupling base and avoid that other
surfaces other surfaces rest on the ground.
Figure 1: Actuator’s Position on the Wooden Pallet
Figure 2: Position of the Output Shaft
In case of long-term storage (more than four months), additionally perform the following measures:
• Coat the coupling parts (spool piece base, flanges, bushings, joints) with protective oil or grease.
• If possible, blank off the spool piece base flange by a protection disk.
• Provide a tarpaulin cover or some other means of protection, especially if the storage is outdoor.
• It is important to periodically operate the actuator with filtered, dehydrated and lubricated air while in a storage.

LPC Compact Actuator Series FCD LFENIM0002-00-AQ 07/14
2.2 Connection With Valve and Mounting Kit
The LPC actuator is usually supplied with the spool piece already assembled. To assemble the actuator onto the valve,
perform the following steps:
1. Check the mounting surfaces, the stem adaptor and the spool piece to assure the proper fit. Clean the flange of the
valve and spool piece to remove oils and greases since the torque is transmitted by friction. Also remove any rust
that may have occurred during the storage.
2. Secure the valve in the closed/open position, if possible, with the stem vertical. Lubricate the valve stem in order to
ease the assembly. Place the stem adaptor on the valve stem.
3. Lift the actuator using a proper lifting system. Position the actuator over the valve and lower to engage the stem
adaptor to the actuator bore. Continue to lower until the spool piece sits on valve mounting surface. This coupling
has to take place without force and only with the weight of the actuator. The mounting bolts (or studs) of the valve
should easily fit into the bolt holes of the spool piece without any binding. If needed, turn or stroke the actuator a few
degrees and/or adjust the actuator travel-stops.
4. The mounting nuts (or bolts) connecting the base of the spool piece to the valve flange must be evenly tightened
according to specific tables, available upon request to Flowserve After Sales Department.
2.3 Travel-stop Bolts and Accessories
All actuated valves require accurate travel-stop adjustments at both ends of the stroke to obtain optimum performance
and valve seat life. Adjust the travel-stop bolts of the actuator for the proper open and close valve positions, per valve
manufacturer’s recommendations.
The LPC actuators have travel-stop adjustments in both the clockwise and counter-clockwise directions. The
+/- 5-degree adjustment feature provides shaft rotation from 80 to 100 degrees overall. The adjustment of the travelstops is performed in accordance with the following steps. Refer to Figure 15.
• Pneumatic cylinder stop (19): Loosen the hex nut (20) with a proper wrench. Screw or unscrew the stop (19), using
a proper Allen key, while keeping the hex nut stationary. Tighten the hex nut.
• Housing stop (19): Loosen the hex nut (20) with a proper wrench. Screw or unscrew the stop (19), using a proper
Allen key, while keeping the hex nut stationary. Tighten the hex nut.
Adjust the travel stop bolts of the actuator for the proper open and closed valve positions, per valve manufacturer’s
recommendations. Pneumatically stroke the actuator several times to assure proper operation. If the actuator is
equipped with a switch, positioner or other accessories, adjusts them at this time.
2.4 Pneumatic Supply Fluids
To prolong actuator life use only clean, dry pneumatic supply fluids. Lubricated fluids are not required; however, they
are recommended, particularly for high cycle applications. Do not use lubricated fluids with positioners, as they may
damage the positioner.

LPC Compact Actuator Series FCD LFENIM0002-00-AQ 07/14
2.5 Initial Operation
Before initial operation of the actuator, perform the following checks:
• Check that all electrical supply, control and signal lines are properly connected, by following the dedicated customer
procedures.
• Check that the pressure and quality of the supply fluids are as prescribed.
• Check the absence of leaks in the pneumatic connections. If necessary tighten the pipe fittings.
2.6 Fail Open and Fail Close Configuration

Maintenance Instructions
4
LPC series compact actuators are designed to offer the greatest ease of operations of assembly, disassembly and maintenance. The maintenance and disassembly do not require special equipment or special or large wrenches. Furthermore
the joints among the moving parts of the actuator are made exclusively through pins and then not using bolts to be
tightened with specific torques.
LPC compact actuators do not need maintenance for a long period, even if they are working in severe condition. The
lifetime of these actuators is guaranteed for 25 years with a regular and programmed maintenance operation every five
years. However, if the actuator operation happens infrequently, it is recommended to periodically check the actuator by
performing the following steps:
• In the plants, where it is possible, carry out a few opening and closing operations, involving all the control unit
components, checking that the actuator operates correctly and within the required stroking times.
• Check that all the signals (pneumatic and electric) arriving at the actuator are correct and that the supply fluid pressure is within the required range. Check for the absence of leaks in the pneumatic connections. If necessary, tighten
the pipe fittings.
• Check the paint coating. If some areas are damaged due to accidental events, retouch them according to paint
procedure supplied along with the actuator documentation.
In case of scheduled preventive maintenance, or following accidental events, refer to the following maintenance
instructions regarding the main actuators components (pneumatic cylinder and housing).

Disposal of
Decommissioned
6
Actuators
Actuators that are to be decommissioned permanently due to a plant closure or for another reason must have the
stored energy in the spring neutralized. This can be done in several ways:
• Decommissioning by filling with concrete – following proper removal of the actuator from any hazardous areas,
the spring module may be neutralized by cutting a small opening in the end or side of the spring can and filling
the spring can with liquid concrete and allowing the concrete to dry. This will eliminate any possibility of spring
decompression if it were to be removed from the actuator without following proper procedures.
• Decommissioning by cutting the spring – following proper removal of the actuator from any hazardous areas, the
spring module may be neutralized by cutting a small opening in the side of the spring can and accessing the spring
coils. The spring coils are then cut using a torch to relieve all compression and stored energy. Care should be taken
that the opening in the spring can is sufficiently small to prevent any pieces of the spring from escaping when the
spring is cut.
a WARNING: Failure to neutralize the spring in the actuator or to follow these instructions could lead to injury to
personnel or property damage.
Either method is acceptable to Flowserve although the method outlined in the first point is preferred, as the stored
energy in the spring is not suddenly released when the spring is cut. Hence, this is the safest method.
No actions need be taken on any other portions of the actuator to decommission it.
