FULLY WELDED BALL VALVES - FEATURES AND BENEFITS
One of the most trusted valves in the petroleum industry, it combines the strength of forged components with alightweight and compact spherical design.
CAMERON Fully Welded Ball Valves satisfy ASME/ANSI 150 through 2500 (PN 20 through PN 420) and API 2000 through 10,000 standards. Made of forged steel to assure uniform fine grain structure and toughness, they may be specified in sizes from 2 in. to 56 in. (50 mm to 1400 mm). Engineered for heavy duty, maintenance free performance, the CAMERON Fully WeldedBall Valve is commonly selected for a number of applications, including:

• • • • • • •

Gas transmission

Products pipeline Measurements skids Dehydration systems Gas separation systems Natural gas storage Dryer service

• • • • • •

NGL plants NGL pipeline Compressor stations CO2 services Offshore Subsea

The distinctive design of the CAMERON Fully Welded Ball Valve gives it maximumstrength at minimum weight as well as maximum resistance both to pipeline pressures and stresses. The compact, spherical design also eliminates body flanges, thus reducing overall size and potential leak paths. PTFE lip seal. PTFE delta seal. Stem sealant injection. Compact body design gives maximum strength with minimum weight.
Floating seat ring with seat to ball seal. Various seat arrangementsavailable (see pages 4 and 5).

Forged body and ball provides superior ductility and strength for added safety.

Sealant port with check valve permits safe injection of sealant for fast, simple restoration of tight shut-off.

Body bleed fitting allows double block and bleed testing of valve seals in either open or closed position.

Trunnions encased in PTFE impregnated stainless steelbearings for smooth operation without lubrication.

FULLY WELDED BALL VALVES FEATURES AND BENEFITS
REPLACE STEM SEAL In the unlikely event of a stem seal needing replacement, it can be accomplished safely with the valve in service. With the body cavity vented all line pressure to the stem area is also vented. (Please contact yourCameron’s Valves & Measurement group representative to obtain maintenance procedures.) SAFEGUARD DOWNSTREAM WORK With the valve closed and the vent fitting open, the possibility of the line media reaching a work area is removed. FIRE TESTED FOR SAFETY CAMERON Fully Welded Ball Valves can be supplied to API 6FA, API 607 and ISO 10497 standards. Fire test programs are ongoing. If industry standardschange or customer requirements vary from above, call your Cameron’s Valves & Measurement group representative.

STEM SEALS

Delta seals and lip seals made of PTFE are incorporated in the upper stem area. PTFE is a low friction, non-deteriorating material that is not subject to rapid decompression explosion. Most valve sizes have a provision for the injection of sealant to establish a secondaryseal.

TRUNNION SUPPORTED BALL ALLOWS LOW TORQUE OPERATION

Regardless of size or pressure rating, every CAMERON ball valve is trunnion mounted. High strength forged stems are located in PTFE impregnated stainless steels bearings for smooth, accurate operations. Trunnion mounted stems absorb the thrust from line pressure, preventing excess friction between the ball and seats, so even at...
