Product Detail

The Marine Pneumatic & Hydraulic Trunnion Ball Valve for Offshore Engineering is an elite, heavy-duty automated flow control solution engineered specifically for offshore platforms, FPSO vessels, and deep-water marine subsea pipelines. Fabricated from high-integrity forged alloys (such as Duplex Stainless Steel F51/F60 or low-temperature carbon steel), the valve features a robust trunnion-mounted fixed-ball architecture that absorbs massive pipeline thrusts and operational vibrations. Driven by heavy-duty pneumatic or high-pressure hydraulic actuators, it ensures rapid, fail-safe remote control and critical emergency shutdown (ESD) performance. Configured with either resilient soft seats or HVOF metal-to-metal sealing, it delivers exceptional reliability and bubble-tight shut-off in aggressive marine environments. 批量图
