CAMERON AAP3798102-00140 | High-Pressure Gate Valve

Description

Technical Specifications

Key Features and Advantages

The **CAMERON AAP3798102-00140** combines extreme pressure integrity with corrosion resistance for critical hydrocarbon applications. Its dual-seal design ensures zero leakage under full-rated pressure, exceeding API 6A standards by 25%. The super duplex stainless steel construction provides chloride stress corrosion cracking resistance, ideal for sour gas environments. Pressure-balanced stem design reduces operating torque by 40% compared to conventional valves.

Advanced flow control: Streamlined bore minimizes turbulence and erosion in high-velocity flow conditions. Integral backseat allows packing replacement under pressure, eliminating system downtime. The valve’s fire-safe design meets API 6FA requirements, maintaining seal integrity during fire scenarios.

Application Areas

The **CAMERON AAP3798102-00140** is deployed in subsea Christmas tree systems, providing reliable isolation in 10,000ft water depths. Offshore production platforms utilize its NACE compliance for H2S-rich wellhead applications. Pipeline pigging stations rely on the full-port design for unrestricted tool passage during maintenance.

In refinery settings, the valve handles hot oil service up to 200°C with thermal stability. Enhanced oil recovery (EOR) injection systems benefit from its erosion-resistant trim in high-sand content environments. LNG liquefaction plants employ the cryogenic-capable variant for cold service down to -160°C.
