GATE VALVE GENERAL WARNING

READ AND UNDERSTAND ALL INSTRUCTIONS. Failure to follow may result in serious personal injuryand damage not only to the equipment but also the environment.

1. Safety is a combination of staying alert, common sense, and experience with the oil field equipment andenvironment. Read this manual prior to operating and servicing the valve. Be familiar with the operationterminologies of gate valves and oil field equipment.

2. This document includes basic valve repair guidance. The field service personnel shall be fullytrained in all aspects of handling pressure control equipment, as well as the job that they are goingto perform. If any of the procedures and policies listed in this document cannot be followed, contacta Cameron Representative for the best course of action.

3. Proper Personal Protective Equipment(PPE) shall be utilized according to Company policies. Always use

proper tools when servicing the equipment.4. Ajob hazard analysis(JHA) must be performed prior to beginning any service on a well location. A

JHA review meeting will be held with all affected rig personnel PRIOR to the commencement of workto review the results of the JHA, evacuation routes, emergency contacts, etc. All meeting attendees anda Company Representative will sign-off on the JHA to acknowledge this meeting has taken place.

5. Be aware of unexpected circumstancesthat may arise when operating or servicing the valve. Utilizethe Step Back 5X5 process in order to assess the hazards posed before, during, and after the servicing ofequipment under pressure or with the potential of hazardous chemicals present. Be familiar with thecompanys and facilitys 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 requirementsshall be met before working on the valve. Re-quirements of fully tested pressure barriers prior to servicing the valve shall be observed. Cameron

recommends that two mechanical pressure barriers is the preferred practice. The Lower Master Valve

(LMV) is a critical valve and additional precautions should be taken to ensure that the mechanical

pressure barriers are functioning correctly prior to any work being carried out on this particular valve.

7. Always check for any trapped pressurebefore servicing the valve. All valves downstream of the pressurebarriers must be cycled several times to release any trapped pressure.

8. Ensure the chemical and physical properties of the fluid flow product inside the valve are known. ObtainapplicableMaterial Safety Data Sheets(MSDS) for commonly encountered chemicals such as hydrogensulfide, cements, etc. in order to identify appropriate PPE to use, emergencies, procedures, and methodsor exposure control.

9. Always use correct lifting devicesand follow safety rules for handling heavy products. The actual valveweight can vary for different valve configurations. Valve should be lifted from the valve body, flangeor studded end connection. Never lift valve from the hand wheel, hand wheel connection, actuatoror lower stem protector.

10. Cameron manufactures a variety of valve models with different features and operating requirements.

Be certain of the valve model and refer to the appropriate manual, before attempting any operation or

service on the valve.

2.4 Surface Safety Valve Requirements (SSV)

2.4.1 SSV Inspection

The following procedure is to be performed in conjunction with applicable APIspecification recommendations.

2.4.1.1 Valve Inspection Procedure Prior to Hook-Up

Visually inspect and contact Cameron for any repair work.

1. Valves Prepped for Actuator

a. End connection ring grooves and bonnet face for any damage.

b. Insure that the body thru bore and cavity are free of all foreign material,such as solid particles, grit, trash, etc.

2. Valve with Actuator Installed

a. End connection ring grooves for any damage.

b. Insure that the body thru bore is free of all foreign material, such assolid particles, grit, trash, etc.

2.4.2 SSV Installation and Testing

1.) The Cameron SSV operates properly when installed in any orientation.

2.) Refer to the actuator manufacturer's instructions for information oninstalling the actuator onto the valve.

3.) Install the valve and actuator assembly (SSV) onto the Christmas Tree using

the correct end connection gaskets. Apply lubrication to the stud threadsand nut bearing faces and tighten in criss-cross pattern. See BOLT TORQUEsection of this manual for bolt torque requirements.

3.0 VALVE OPERATION

STOP

VALVE OPERATION

1. Be aware of the surrounding environment and the valve condition when operating thevalve. Be certain of the gate position (open/close) before operating the valve. Be awarethat unexpected circumstances may arise when operating or servicing the valve. Reviewthe completed JHA and perform a Step Back 5X5 to prepare for unplanned situations.

2. Always use the correct operating media for the actuator cylinder.

3. Do not exceed the operating pressure rating of the actuator cylinder. Exceeding themaximum cylinder pressure rating can damage the actuator or the valve.

4. If the valve does not operate to the full open or full close position refer to the Trouble-shooting Section of this manual.

5. When pressure is bled from the valve bore, there may be trapped pressurein the cavitywhen the valve is in either the open or close position. The valve should be cycled to relievethis pressure.

SD-045055-10 Rev 01

3.1. Open Valve

3.1.1. The valve is opened by applying control pressure to the actuator cylinder.

3.2. Close Valve

3.2.1. The valve is closed by releasing control pressure from the actuator cylinder. Thisallows pressure in the valve cavity acting across the stem and the springs in theactuator to close the valve.

The gate must be positioned either "fully-open" or "fully-closed". Leaving the valve in thepartially open position can cause throttling and damage the valve components.

3.3. Actuator Operation

3.3.1. Refer to the actuator manufacture procedures for the actuator operating instructions.


12/19

Page 12




4.0 PERIODIC MAINTENANCE

STOP

VALVE CAVITY LUBRICATION

1. Danger: Lubricating the valve involves injection into the valve body. This can present a hazard while the

well is owing or under pressure. Be aware of unexpected circumstances during or after lubricating the

valve. Review the completed JHA and perform a 'Step Back 5x5" to prepare for unplanned situations.

2. Isolate valve pressure source and release valve pressure before lubricating the valve whenever possible.

If a valve is lubricated under pressure, a second check valve or needle valve should be manifolded onto

the grease tting as a second barrier. This can isolate pressure if the grease tting check fails. Reference

the facility's work instruction on grease gun safety in order to verify condition of grease equipment before

performing the work.

3. Besides wearing appropriate PPE, be sure to read and understand the Material Safety Data Sheet (MSDS)

of the 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 the physical and chemical properties of well uids. Stroke the valve

to verify the release of any trapped pressure. Use proper unseating tool to check any residual trapped

pressure through grease tting.

5. When removing the tting cap be certain the tting does not rotate with the cap. If a constant pressure

release is heard when loosening the cap, re-tighten the cap and plan to replace the tting.

6. During lubrication or other maintenance operations, do not place any part of one's body in front of thetting, especially when removing the tting or tting cap.

7. The standard gate valves do not have a buried check valve. However, some special customer designs

may have a buried check valve with the word "CHECK" stamped next to the grease tting.

8. During lubrication do not exceed the rated working pressure of the valve. A slowdown in the pumping

speed shows resistance and can be an indication that the valve cavity is full.

SD-045055-05 Rev 01

4.1.1. Valve Body Cavity Lubrication

Proper lubrication will improve the performance and the life of the valve. It is recommendedto lubricate the valve cavity after ten operating cycles. One cycle equals opening and closing the valve one time. The service interval can vary according to application, fluids usedand well conditions. If pressure is equalized across the valve before it is opened, the serviceinterval can be extended. If the valve is removed from service, the body cavity should belubricated before it is returned to service or put in storage.

4.1. Lubrication

NOTICE


13/19

Page 13




If it becomes necessary to cement, acidize, frac through, or subject the valve to any otherunusual service, it is recommended to lubricate the valve body cavity before the operationAfter the operation, flush the valve with an appropriate cleaning/neutralizing fluid. Then

operate the valve with fresh water or appropriate neutralizing fluid in the line. Finally,lubricate the valve body cavity again. Cycling the valve during flushing and the lubricationwill greatly improve the effectiveness of the maintenance.

The lubricant selection chart, Table V, recommends the proper grease for different valveservice conditions. Table IV shows the amount of grease required for different Model FL andFLS valves. Lubrication of the valve cavity is performed through the grease fitting locatedon the actuator bonnet as follows:

4.1.1.1. Isolate the valve from flowline pressure.

4.1.1.2. Operate the valve to the fully-open position.

4.1.1.3. Remove the safety cap from the grease fitting located on the actuator bonnet.

When removing the grease fitting cap be certain the fitting does not rotate withthe cap. Do not place any part of one's body in from of the fitting vent.

4.1.1.4. Attach the high-pressure grease gun to the bonnet grease fitting. Pump the requiredamount of grease into the valve body. Refer to Tables IV and V.

The lubricating pressure must not exceed the rated working pressure of the valve

4.1.1.5. When the valve cavity has been filled, remove the grease gun and re-install thegrease fitting cap. For Cameron actuators, torque to 50-60 ft-lb (70-85 Nm). Referto the actuator manufature procedures for non-Cameron actuators.

4.1.1.6. Operate the valve several times, and then return it to its normal operating position

The information in this table is based on API-6As recommended torques for a given bolt size. The information is

presented for the convenience of the user and is based on assumptions of certain coefficients of friction (cf). Thecoefficients of friction are based on approximations of the friction between the studs and nuts, as well as the nuts andflange face. A coefficient friction of 0.13 assumes the threads and nut bearing surfaces are bare metal and are welllubricated with thread compound. A coefficient of friction of 0.07 assumes the thread and nuts are coated with afluoropolymer material.It is essential that threads and nut faces are well lubricated with an appropriate lubricant prior to assembly. Accept-able lubricants include thread compounds that meet API RP 5A3/ISO 13678. (Ref. Cameron PN: 2737980-02 for 1 Lbcan).Studs and nuts coated with a fluorapolymer material in accordance with a Cameron procedure do not require lubrica-tion. However, a light coat of API RP 5A3/ISO 13678 thread compound is recommended as aid to assembly.

7.0 ORDERING REPLACEMENT PARTS

The only information needed for ordering replacement parts for a Cameron gate valve is theoriginal valve assembly part number and the description of the part. The valve assembly part

number is stamped on the valve body nameplate. It is recommended that a description ofthe valve assembly (size, pressure, trim) is included as a check on the assembly number, butthis is not necessary if the assembly number is clearly readable.

It is not recommended to order replacement parts by using the part number off the oldpart or by referring to a file copy of the valve assembly bill of material. If an engineeringchange has been implemented to the valve assembly to replace one component part number with another, the only way to ensure getting the updated component is to referencethe valve assembly number and to reference the part by description (gate, seat, stem, etc.)Part descriptions are shown in the Parts List section of the manual. Cameron personnel canthen check the latest revision of the assembly bill-of-material to obtain the appropriate andcurrent replacement part number.

Contact your Cameron representative for replacement part inquiries.
