Product Detail

The Heavy Duty Marine Pneumatic and Hydraulic Forged Steel Metal-to-Metal Seated Trunnion Mounted Ball Valve is an elite, severe-service automated isolation solution engineered specifically for offshore platforms, FPSO vessels, and deep-water subsea manifolds. Fabricated from high-integrity forged alloys such as Duplex Stainless Steel (F51/F60) or Super Duplex, the valve features a robust trunnion-mounted fixed-ball architecture that absorbs massive pipeline thrusts and operational vibrations. Powered by heavy-duty pneumatic or high-pressure hydraulic actuators, it ensures rapid, fail-safe remote control and critical emergency shutdown (ESD) performance. Enhanced with an HVOF-sprayed tungsten carbide metal-to-metal sealing system, it delivers exceptional resistance to sand erosion, high differential pressures, and aggressive marine environments.

Design Description

Marine-Grade Forged Alloys: Constructed from corrosion-resistant forged duplex or super duplex stainless steels, providing superior mechanical strength and resistance to marine stress corrosion cracking.
Trunnion-Mounted Stability: The fixed-ball design minimizes operating torque under extreme pressures and prevents ball displacement during high-velocity offshore fluid surges.
Pneumatic & Hydraulic Actuator Integration: Compatible with heavy-duty rack-and-pinion, scotch-yoke pneumatic units, or high-pressure hydraulic cylinders for fast ESD action.
HVOF Metal-to-Metal Armor: Ball and seats hardened with ultra-durable Tungsten Carbide or Stellite, ensuring long-term bubble-tight integrity in abrasive, sand-producing oil wells.
