1 General Information
1.1Using
The following instructions are designed to assist in disassembling, reassembling and troubleshooting Flowserve Valtek valves equipped with VL-ES actuators. Separate installation, operation and maintenance instructions cover additional features (such as handwheels, limit stops, fail-safe systems, limit switches or positioners). Product users and maintenance personnel should thoroughly review this bulletin in conjunction with any handwheels or other accessory equipment before installing, operating or performing any maintenance on the valve. In most cases, Flowserve valves, actuators and accessories are designed for specific applications (e.g. with regard to medium, pressure, temperature). For this reason they should not be used in other applications without first contacting the manufacturer.
1.2Applicability
The following instructions are applicable to the maintenance and installation of VL-ES actuators only. This document should be used in conjunction with the appropriate Installation, Operation and Maintenance Instructions specific to the model of the valve on which the actuator is installed.
1.3Terms Concerning Safety
The safety terms DANGER, WARNING, CAUTION and NOTE are used in these instructions to highlight particular dangers and/or to provide additional information on aspects that may not be readily apparent.
bDANGER: indicates that death, severe personal injury and/or substantial property damage will occur if proper precautions are not taken.
cWARNING: indicates that death, severe personal injury and/or substantial property damage can occur if proper precautions are not taken.
aCAUTION: indicates that minor personal injury and/or property damage can occur if proper precautions are not taken.
NOTE: indicates and provides additional technical information which may not be obvious, even to qualified personnel.
Compliance with other notes, which may not be particularly emphasized, with regard to transport, assembly, operation and maintenance and with regard to technical documentation (e.g. in the operating instructions, product documentation or on the product itself), is essential in order to avoid faults, which, in and of themselves may directly or indirectly cause severe personal injury or property damage.
1.4Protective Clothing
Flowserve products are often used in problematic applications (e.g. under extremely high pressures or with dangerous, toxic or corrosive mediums). 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 (e.g. protective clothing, gloves, glasses and respirator as required).
1.5 |
Qualified Personnel |
|
|
Qualified personnel are people who, on account of their training, experience, instruction and knowledge of relevant standards, specifications, accident prevention regulations and operating conditions, have
flowserve.com
Valtek VL-ES Actuators FCD VLENIM0114-00 – 09/06
been authorized by those responsible for the safety of the plant to perform the necessary work and who are able to recognize and avoid possible dangers.
bDANGER: Before installation, check the order number, serial number and/or the tag number to ensure that the valve/actuator is correct for the intended application.
cWARNING: Standard industry safety practices must be followed when working on this or any process control product. Specifically, personal protection and lifting devices must be used as warranted.
1.6Installation
1.6.1 Do not insulate extensions that are provided for hot or cold services.
1.6.2 Pipelines must be correctly aligned to ensure that the valve is not fitted under tension.
1.6.3 The user must provide fire protection.
1.7Spare 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 manufactures. If Flowserve products (especially sealing materials) have been on store for long periods of time check these products for corrosion or deterioration before using them. The end user must provide fire protection for Flowserve products.
1.8Service / Repair
To avoid possible injury to personnel or damage to products, the safety terms must be strictly adhered to (see Section 1.3). Modifying this product, substituting non-factory parts, or using maintenance procedures other than those outlined in this instruction manual can drastically affect performance, be hazardous to personnel and equipment, and may void existing warranties. Between the actuator and the 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. 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.
cWARNING: Before products are returned to Flowserve for repair or service, Flowserve must be provided with an MSDS (Material Safety Data Sheet) and a certificate, which confirms that the product has been decontaminated. Flowserve will not accept deliveries if the MSDS and the
certificate have not been provided (a form can be obtained from Flowserve). Since the packing box cannot be cleaned without removing packing, valve packing should be removed and the packing area flushed as part of the cleaning.
1.9Storage
In most cases, Flowserve products are manufactured from stainless steel. Products not manufactured from stainless steel are provided with an epoxy resin coating. This means that Flowserve products are well protected from corrosion. Nevertheless, Flowserve products must be adequately stored in a clean, dry environment. Plastic caps are fitted to protect the flange faces by preventing the ingress of foreign materials. These caps should not be removed until the valve is actually mounted into the system.

1.10 Product Variations
These instructions cannot claim to cover all the details of every possible product variation, nor in particular can they provide information for every possible example of installation, operation and maintenance. This means that the instructions normally include only the directions to be followed by qualified personnel using the product for its defined purpose. If there are any uncertainties in this
respect, particularly in the event of missing product related information, clarification must be obtained via the appropriate Flowserve sales office.
2 Unpacking
While unpacking the actuator, check the packing list against the materials received. Lists describing the actuator and accessories are included in each shipping container.
2.1 Position the lifting straps and hoist to avoid damage to the tubing and mounted accessories when lifting the actuator from the shipping container.
cWARNING: When lifting an actuator with lifting straps through the yoke legs, be aware that the center of gravity may be above the lifting point. Therefore, support must be given to prevent the actuator from rotating, causing serious injury to personnel or damage to nearby equipment.
2.2 Contact your shipper immediately in the event of shipping damage.
2.3 Contact your Flowserve representative with any other problems.
3 Valve Installation
Prior to installation, make sure adequate overhead clearance is provided for the actuator to allow for proper removal from the valve body and for proper maintenance. Refer to Table I.
