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.
