CAMERON T31MAX High-efficiency Fully Welded Ball Valve CAMERON T31MAX High-efficiency Fully Welded Ball Valve As one of the most trusted valves in the petroleum industry, the CAMERON T31MAX provides the strength of forged components with a lightweight and compact spherical design. Combined with Cameron’s MAXTORQUE™ high-efficiency gear operator, the package gives new meaning to the words “user friendly.” 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 ensure uniform fine grain structure and toughness, they can be specified in sizes from 2” to 56” (50 mm to 1400 mm). MAXTORQUE high-performance gears PTFE lip seal PTFE delta seal Stem sealant injection Compact body design gives increased strength with reduced weight Forged body and ball provides superior ductility and strength for added safety Floating seat ring with seat to ball seal; various seat arrangements are available (see pages 4 and 6) Sealant port with check valve permits safe injection of sealant for fast, simple restoration of tight shutoff Trunnions encased in PTFE impregnated stainless steel bearings for smooth operation without lubrication Body bleed fitting allows double block-and-bleed testing of valve seats in either open or closed position 1 MAXTORQUE High-Performance Gears MAX Series Drive Train Features MAX Series Benefits • 70% base efficiency • Reduced work to close by up to 75% • Double O-ring sealing system - Reduced turns and/or input force required to operate • 6 to 12+ teeth in contact versus 1.5 to 2.5 - Increased speed to close by up to 75% with the same input • Reduced need for actuators • Near-zero backlash for improved process control • Rugged ductile iron housings (carbon steel utilized above 100,000 ft-lb) • Smaller EMOs reduce cost of actuation packages • Bronze gears • Smaller actuation packages reduce weight and piping loads Double enveloping worm gear Single enveloping worm gear Single start Multistart MaxTorque Tooth Contact of 6.6 to 10.7 Standard gears Maximum Tooth Contact of 2.96 Typical Project Savings Project Scope Qty.

Sealing System Prevents Particulate and Water Ingress Quality Manufacturing Double sealing at top • Rigorous PC/PLC cycle testing and qualification Primary: At indicator Secondary: Top of hub • Direct-mount capability reduces cost and chance of stem misalignment/valve failure • Designed to handle torques in excess of 1,000,000 ft-lb • Made in Maine, USA Input seals 3 Standard Seat Design In service since the early 1960s, the standard seat arrangement has proven to be of sound design. This arrangement is available in all CAMERON fully welded ball valves and includes all features and benefits indicated on the preceding pages. Features and Benefits Upstream Sealing At low pressure, seat-to-ball contact is maintained by Belleville springs. At higher pressures, seat contact is reinforced by line pressure. Automatic Internal Relief of Body Pressure Relief of excess body cavity pressure is automatic, avoiding dangerous pressure buildup. Any pressure exceeding downstream line pressure by approximately 200 psi pushes the downstream seat away from the ball, allowing the pressure to relieve into the pipeline. Rotating Seat Rings The exclusive rotating seat feature is standard in the CAMERON fully welded ball valve sizes 14” (350 mm) and larger. Both seats rotate 15 degrees each time the valve is closed, exposing a new pinch point and evenly distributing seat wear. Distributed Seat Wear The pinch point is the area of the seat insert that experiences an increased velocity when the valve is seated closed and unseated open. This is where the seat seal experiences the most wear, and in most valves, where a leak path begins. By rotating the seat ring, the pinch point wear is distributed throughout the seat seal, providing an increase in seat life. Prevents Buildup In some services, a valve can experience harmful sediment buildup around the seat ring. This can cause the seat to stick and not seal properly. The CAMERON fully welded ball valves, with exclusive rotating seat, can handle these harsher services. As the seat rotates, it will prevent any buildup, or breaks up existing buildup. 4 LINE PRESSURE TRAPPED LINE PRESSURE ESCAPING PRESSURE Features and Benefits 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 subjected to rapid decompression explosion. Most valve sizes have a provision for sealant injection to establish a secondary seal. Trunnion-supported Ball Allows Low-torque Operation Regardless of size or pressure rating, every CAMERON fully welded ball valve is trunnion mounted. High-strength forged stems are located in PTFE impregnated stainless steels bearings for smooth operation. Trunnion mounted stems absorb the thrust from line pressure, preventing excess friction between the ball and seats, so even at full rated working pressure, operating torque stays low. Double Block-and-bleed Whether in the fully open or fully closed position, pressure on each side of the ball is blocked from the VALVE OPEN body cavity by the seat ring. The body cavity can then be bled down or drained through the body port. When you block-and-bleed a CAMERON fully welded ball valve, the following can be accomplished: Test Valve Integrity When the valve body is vented, the seat seal’s integrity is verified. This test can be performed VALVE CLOSED with the valve open or closed prior to facility maintenance. By verifying valve integrity, unforeseen valve leakage can be prevented. Secondary Seat Seal The sealant injection system provides a fast, simple way of restoring tight shutoff if any foreign object should damage the sealing surfaces. The injection system also can be used for routine flushing of the seat ring area in services where this may be required. 5 Alternate Seat Design The valve is available with double-acting and metal-to-metal seats to accommodate a variety of applications and customer preferences. Double Acting Conventional Upstream Sealing With upstream pressure, the bi-directional body-to-seat seal is pushed toward the front sealing face of its retaining pocket. This creates an unbalanced pressure annulus between the body seal and the ID of the seat insert, forcing the seat insert against the ball. Downstream Sealing With downstream pressure, the bi-directional body-to-seat seal is pushed toward the back sealing face of its retaining pocket. This creates an unbalanced pressure annulus between the OD of the seat insert and the body seal diameter, also forcing the seat insert against the ball. Standards and Specifications Double Acting – T32 SIZES • 8” to 48” (200 mm to 1200 mm) PRESSURE CLASSES • ASME/ANSI Class 150 to 900 (PN 20 to PN 150) OPERATING TEMPERATURES • -50° F to 250° F (-46° C to 121° C) 6 Additional Features and Benefits The CAMERON T31MAX valve series offers the established features and benefits of the T31 valve with the addition of leading-edge Drive Train technology. The MAX valve series offers a product that adds power steering to one of the leading valves in the market. In-line Replaceable Stem Seals Standards and Specifications In the unlikely event of a stem seal needing replacement, Sizes this can be accomplished safely with the valve in service. With the body cavity vented, all line pressure to the stem area also is vented. (Please contact your sales 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 standards change or customer requirements vary from above, please contact your sales representative.
