Product Detail

The LF2 Low Temperature Carbon Steel Pneumatic Trunnion Ball Valve is a high-performance automated solution engineered specifically for extreme cold environments and cryogenic auxiliary services. Built with ASTM A350 LF2 forged steel, this valve maintains superior impact toughness at temperatures as low as -46℃. The full-port design ensures zero flow resistance, while the trunnion-mounted structure, combined with a powerful pneumatic actuator, provides reliable, low-torque operation for rapid emergency shut-off or precise process control in arctic pipelines and gas processing plants.

Design Description

Exceptional Low-Temp Resilience: The A350 LF2 forged body is impact-tested to ensure maximum safety against brittle fracture in sub-zero climates.
High-Efficiency Full Port: The internal bore matches the pipe ID exactly, minimizing pressure drop and allowing for seamless pigging operations.
Pneumatic Automation & Safety: Equipped with high-torque pneumatic actuators (Rack & Pinion or Scotch Yoke) for fast response times and fail-safe (Spring Return) options.
Trunnion-Mounted Stability: The fixed-ball design transfers fluid pressure loads to the bearings, preventing seat deformation and ensuring smooth operation even at high pressure differentials.
API 6D & Fire-Safe Compliance: Features a blow-out proof stem, anti-static design, and is certified to API 607 for reliable sealing during fire emergencies.
