Box 1212 Houston, Texas 77251-1212 713-939-2211 http://www.c-a-m.com TC148-2 3 GENERAL WARNING READ AND UNDERSTAND ALL INSTRUCTIONS. Failure to follow may result in serious personal injury and damage not only to equipment but also the environment. 1. Safety is a combination of staying alert, common sense, and experience with oil field equipment and environment. Read this manual prior to operating and servicing the FL and FLS valve. Be familiar with operation terminologies of gate valves and oil field equipment. 2. This document includes basic valve repair guidance. The field service personnel shall be fully trained in all aspects of handling pressure control equipment as well as the job they are going to perform on the FL and FLS valve models. If any procedures and policies listed in this document cannot be followed, contact a Cameron Representative for best course of action. 3. Proper Personal Protective Equipment (PPE) shall be utilized according to Company policies. Always use proper tools when servicing equipment. 4. A Job Hazard Analysis (JHA) must be performed prior to beginning service on a well location. A JHA review meeting will be held with all affected rig personnel PRIOR to commencement of work to review results of the JHA, evacuation routes, emergency contacts, etc. All meeting attendees and a Company Representative will sign off on the JHA to acknowledge meeting has taken place. 5. Be aware of unexpected circumstances that may arise when operating or servicing valve. Utilize Step Back 5X5 process in order to assess hazards posed before, during and after servicing of equipment under pressure or with potential of hazardous chemicals present. Be familiar with company’s and facility’s Lockout/Tagout program in order to ensure all sources of energy (i.e. electrical, pneumatic, pressure) are isolated and/or de-energized prior to beginning work. 6. All governmental or Company safety requirements shall be met before working on valve. Requirements of fully tested pressure barriers prior to servicing valve shall be observed. Cameron recommends two mechanical pressure barriers is preferred practice. Lower Master Valve (LMV) is a critical valve and additional precautions should be taken to ensure mechanical pressure barriers are functioning correctly prior to work being carried out on this particular valve. 7. Always check for trapped pressure before servicing valve. All valves downstream of pressure barriers must be cycled several times to release trapped pressure. 8. Ensure chemical and physical properties of fluid flow product inside valve are known. Obtain applicable Material Safety Data Sheets (MSDS) for commonly encountered chemicals such as hydrogen sulfide, cements, etc. in order to identify appropriate PPE to use, emergencies, procedures, and methods or exposure control. 9. Always use correct lifting devices and follow safety rules in handling heavy products. The weight of single cavity flanged and hub outlet valves are provided in this document for reference. Actual valve weight can vary for valve block configurations. Never attempt to lift valve by hand. Do not lift from handwheel or handwheel adapter. Valve should be lifted from valve body or end flange outlets. 10. Cameron manufactures a variety of valve models with different features and operating requirements. Be certain of valve model and refer to appropriate manual before attempting operation or service on valve. This document is to assist field personnel in operation and maintenance of the FL and FLS handwheel operated gate valve for valve sizes that are listed in this document. Different documents are available for other FL/FLS valve sizes.

It is available in standard double flange, threaded-end and special block body configurations. The following are standard features of FL and FLS gate valves: 2.1.1 Sealing at gate-to-seat and seat-to-body is metal-to-metal. 2.1.2 Gate and seat assembly has minimum number of parts. One-piece seats and slab gate ensure reliable sealing and simplify field service. The modified Acme gate-to-stem thread allows gate to move back and forth, or float, to seal against seat. 2.1.3 Gate and seat assembly seals in both directions, and gate and seats can be reversed for increased life. 2.1.4 Stem shoulder can be backseated against bonnet to isolate stem seal from valve internal pressure. This feature can be used to prevent leakage to environment in case of stem seal malfunction. Backseating feature can also be used to allow replacement of stem seal while valve is under pressure, a design capability required by API Spec 6A. HOWEVER, replacing stem seal with pressure in valve body is not recommended and should only be done with utmost caution and safety planning. 2.1.5 Non-rising stem prevents cavity pressure increase or displacement of cavity lubricant when valve is stroked open or closed. 2.1.6 All FL and FLS valves have metal-to-metal sealing grease fitting which contains check valve. Stem, gate and seat are lubricated through grease TC148-2 6 fitting which is located on downstream side of stem backseat for safety. No sealant or lubricant ports extend directly into valve cavity. 2.1.7 Valves for 2000 through 5000 psi WP use flat compression-type metal gasket. Seal between valve body and bonnet is a pressure-energized, modified BXstyle metal bonnet gasket on 10,000 through 20,000 psi WP valves. 2.1.8 Stem seal is non-elastomeric design resistant to all well fluids. Different versions of these seals are available that can extend temperature rating to cover all API temperature ratings. 2.1.9 An optional add-on torque multiplier is available for larger FL and FLS valves to provide easier operation.

Be aware of surrounding environment and valve condition when operating valve. Be certain of gate position (open/close) before operating valve. Be aware that unexpected circumstances may arise when operating or servicing valve. Review completed JHA and perform Step Back 5X5 to prepare for unplanned situations. 2. Always use the provided handwheel and stand on stable platform when operating valve. Refer to Tables I through VI for appropriate handwheel size. 3. DO NOT apply more torque than specified values. Do not use cheater pipe or wrench on handwheel to operate. Excessive torque can damage stem pin or other valve parts. 4. If valve handwheel will not rotate, it is possible that rotation is in wrong direction. If there is uncertainty about valve position, open or close, rotate handwheel in both directions before increasing torque. Consider possibility of hydrates (ice) in valve if it is still inoperable. 5. When pressure is bled from valve bore, there may be trapped pressure in cavity when valve is in either open or closed position. Valve should be cycled to relieve pressure. 3.1 Open Valve Valve is opened by turning handwheel counterclockwise (to left) until it stops, then turning handwheel back to right 1/4 to 1/2 turn to relieve stress on operating mechanism. 3.2 Close Valve Valve is closed by turning handwheel clockwise (to right) until it stops, and then backing off 1/4 to 1/2 turn to allow gate to float and seal. Gate must be positioned either “full-open” or “fullclosed”. Leaving valve in partially open position can cause throttling and damage to valve components. Number of turns should always be counted to verify final gate position. Refer to Table VII for number of turns to open and close valve, appropriate valve size and pressure.

DANGER: Lubricating valve involves injection into valve body. This can present a hazard while well is flowing or under pressure. Be aware of unexpected circumstances during or after lubricating valve. Review completed JHA and perform Step Back 5x5 to prepare for unplanned situations. 2. Isolate valve pressure source and release valve pressure before lubricating valve whenever possible. If valve is lubricated under pressure, second check valve or needle valve should be manifolded onto grease fitting as second barrier. This can isolate pressure if grease fitting check fails. Reference facility’s work instruction on grease gun safety in order to verify condition of greasing equipment before performing the work. 3. Besides wearing appropriate PPE, be sure to read and understand Material Safety Data Sheet (MSDS) of grease or any other chemicals being used on the job to ensure adequate control measures are in place. 4. Be aware of trapped pressure and physical and chemical properties of well fluid. Stroke valve to verify release of any trapped pressure. Use proper unseating tool to check any residual trapped pressure through grease fitting. 5. When removing fitting cap be certain fitting does not rotate with cap. If constant pressure release is heard when loosening cap, retighten cap and plan to replace fitting. 6. During lubrication or other maintenance operations, do not place any part of one’s body in front of fitting, especially when removing fitting or fitting cap. 7. Standard FL and FLS gate valves do not have buried check valves like earlier designs. However, some special customer designs and older valve models such as F and FC may have a buried check valve with word “CHECK” stamped next to grease fitting. 8. During lubrication, do not exceed rated working pressure of valve. Slowdown in pumping speed shows resistance and can be indication that valve cavity is full. 4.1 Valve Body Cavity Lubrication Proper lubrication will improve performance and life of valve. It is recommended to lubricate valve cavity after ten operating cycles. One cycle equals opening and closing valve one time. Service interval can vary according to application, fluids used and well conditions. If pressure is equalized across valve before it is opened, service interval can be extended. If valve is removed from service, body cavity should be lubricated before it is returned to service or put in storage. If it becomes necessary to cement, acidize, frac through, or subject valve to any other unusual service, it is TC148-2 14 recommended to lubricate valve body cavity before operation. After operation, flush valve with appropriate cleaning/neutralizing fluid. Then operate valve with fresh water or appropriate neutralizing fluid in the line. Finally, lubricate valve body cavity again. Cycling valve during flushing and lubrication will greatly improve effectiveness of maintenance. Lubricant selection chart, Table IX, recommends proper grease for different valve service conditions. Table VIII shows amount of grease required for different FL and FLS valves. For well flow stimulation operations (i.e. fracturing operations) it is recommended to use Diesel Resistant grease (P/N 713837-10) to lubricate valve body. Lubrication of valve cavity is performed through grease fitting as follows: 4.1.1 Isolate valve from flow line pressure; stroke valve to open position. 4.1.2 Remove grease fitting cap from grease fitting located on bonnet OD. When removing grease fitting cap, be certain fitting does not rotate with cap. Do not place any part of one’s body in front of fitting vent. 4.1.3 Connect grease gun coupler to grease fitting. 4.1.4 Pump appropriate amount and type of lubricant into body cavity. Refer to Tables VIII and IX. 4.1.5 When valve cavity has been filled, remove grease gun and reinstall grease fitting cap. Torque to 50-60 ft-lb (70-85 N•m). 4.2 Stem Thrust Bearing Lubrication Lubricate thrust bearings as often as required to ensure smooth valve operation. Depending upon ambient temperature, use either standard or low-temperature grease listed in Table IX to lubricate thrust bearings. Do not use diesel resistant or high-temperature grease to lubricate thrust bearings. 4.2.1 Connect handheld grease gun to zert fitting on bearing cap. 4.2.2 Pump lubricant into fitting until clean grease appears at vent hole in bearing cap.

Information is presented for convenience of user and is based on assumptions of certain coefficients of friction (cf). Coefficients of friction are based on approximations of friction between studs and nuts, as well as nuts and flange face. Coefficient friction of 0.13 assumes threads and nut bearing surfaces are bare metal and are well lubricated with thread compound. Coefficient of friction of 0.07 assumes thread and nuts are coated with fluoropolymer material.

TC148-2 19 7.0 ORDERING REPLACEMENT PARTS The only information needed for ordering replacement parts for a Cameron gate valve is original valve assembly part number and description of part. Valve assembly part number is stamped on valve body nameplate. It is recommended that description of valve assembly (size, pressure, trim) be included as a check on assembly number, but is not necessary if assembly number is clearly readable. It is not recommended to order replacement parts by using part number off old part or by referring to file copy of valve assembly bill of material. If an engineering change has been implemented to valve assembly to replace one component part number with another, the only way to ensure getting updated component is to reference valve assembly number and part by description (gate, seat, stem, etc. Part descriptions are shown in parts list, Part I.D.). Cameron personnel can then check latest revision of assembly bill of material to obtain appropriate and current replacement part number. Contact Cameron representative for replacement parts for FLS and all other FL gate valves. TC148-2 20
