Cameron T30 Series Features and Benefits
The distinctive design of the CAMERON T30 Series ball valve gives it strength at reduced weight as well as resistance to both pipeline pressures and stresses. The compact, spherical design eliminates body flanges, reducing overall size and potential leak paths. The design also has a smaller volume in the body cavity, minimizing the loss of product during body pressure relief.
Key Features & Benefits
From buried gas transmission lines to offshore installations, the Cameron T30 Series is designed to reduce risk, minimize maintenance, and ensure safe, efficient flow control — even in the harshest conditions. With proven sealing technology, low emissions compliance, and flexible configuration options, the T30 Series sets the standard for long-term valve performance.
Discover the key features that make the T30 Series a pipeline workhorse.
Fully Welded Body
The all-welded construction eliminates body flanges, minimizing potential leak paths and increasing structural integrity. Ideal for buried service and gas transmission lines where zero leakage is critic
Trunnion-Mounted Design
The ball is supported by trunnions, reducing torque requirements and seat wear — even at high pressures. This ensures smoother operation and longer service life compared to floating ball designs
Compact Spherical Body
The spherical shape adds mechanical strength while reducing overall weight and valve envelope dimensions. A smaller body cavity also reduces product loss during pressure relief operations.
Sealing Configurations
Choose from self-relieving seats (T31) for automatic cavity pressure relief, or Double Piston Effect (DPE) and Double Isolation and Bleed (DIB) seats (T32) for critical applications requiring maximum isolation and sealing integrity.
Superior Stem Sealing
Anti-blowout stem design with PTFE lip and delta seals ensures long-term sealing performance. A sealant injection system and check valve provide added safety and secondary sealing capability.
Emissions Compliance
Certified to API 641 and ISO 15848-1 (Class BH and BM), ensuring compliance with strict fugitive emissions regulations from −50 to 375°F (−46 to 191°C).
Fire-tested and Safety Rated
Tested and certified to API 6FA, API 607, ISO 10497, and SIL 3 (IEC 61508), ensuring operational safety under fire and emergency conditions.
Available in a broad range of sizes and pressure classes, from NPS 2 to 56 (DN 50 to 1400) and ASME 150 to 2500 / API pressure class 2,000-, 3,000-, and 5,000-psi, with a wide variety of trims and materials tailored to your process.
Understanding the T30 Series
The CAMERON T30 Series refers to a proven trunnion-mounted ball valve design platform, widely used in critical applications across the oil, gas, and petrochemical industries. However, it’s important to understand that T30 itself is not a valve type or model number — it’s the series designation.
Within this series, two primary seat and sealing configurations exist:
- T31: Designed with self-relieving seats, which automatically vent cavity pressure buildup.
- T32: Available with either Double Piston Effect (DPE) or Double Isolation and Bleed (DIB) options, offering higher integrity sealing for demanding service conditions.
Despite their significance, you won’t find “T31” or “T32” explicitly referenced in the valve part number or order code. Instead, the seat design and internal configuration are determined by the final digits of the part number — the so-called “trim code”.
Each trim code corresponds to a specific combination of:
- Seat material (e.g., PTFE, Nylon, PEEK)
- Valve service (e.g., sour, low-temperature, high-corrosion, ammonia)
- Internal components (e.g., Inconel 625 overlay, duplex, full duplex)
This trim-based system allows for a wide range of material and performance configurations — all built on the same T30 body design — while keeping the external part number structure concise and standardized.
In short:
– T30 = the series platform
– T31 and T32 = seat design types
– Trim code = the key to understanding what’s actually inside the valve
If you’re unsure which configuration suits your application, refer to the trim table:
Or consult a CAMERON representative at Wegman to ensure the right choice based on service conditions, materials, and pressure class.
Conclusion
In short: the CAMERON T30 Series fully welded – Trunnion Mouted Ball Valve, offers a rock-solid solution for operators seeking uncompromised safety, low emissions, and long-term value in harsh environments. Whether you need self-relieving functionality or high-integrity isolation, the T30 Series provides a customizable, high-performance platform you can rely on.
