GVS Welded Body, Trunnion Mounted Ball Valve

GVS Welded Body, Trunnion Mounted Ball Valves

GVS Welded Body Trunnion Mounted Ball Valves are used in the energy industry where high-integrity, maintenance-free isolation is essential, particularly in buried pipelines, high-pressure natural gas transmission, and remote compressor or pump stations. Their fully welded body design eliminates external leak paths, making them ideal for underground installations and power generation fuel systems where safety, durability, and long service life are critical. These valves are commonly used in both conventional and renewable energy infrastructure, offering robust performance in demanding environments with minimal need for servicing.

  • Buried Pipelines: Provide long-term, leak-proof isolation in underground energy transmission lines with zero external bolting.
  • High-Pressure Natural Gas Transmission: Ensure safe, maintenance-free shut-off in long-distance gas pipelines operating at elevated pressures.
  • Remote Compressor Stations: Deliver robust, tamper-resistant valve performance in isolated energy transport hubs with limited access for servicing.
  • Pump Stations: Maintain secure flow control and minimize fugitive emissions in high-volume liquid transport systems.
  • Power Generation Fuel Systems: Safeguard continuous fuel supply to turbines or boilers with high-integrity isolation in both conventional and renewable power plants.

GVS Welded-Body, Trunnion-Mounted Ball Valves are used in Oil & Gas applications where leak prevention, structural integrity, and maintenance-free operation are critical. They are commonly installed in buried natural gas transmission pipelines, compressor and pump stations, and block valve stations, where external bolting and potential leak paths must be eliminated. The fully welded body design offers superior strength and resistance to vibration, pressure, and harsh environments, making these valves ideal for long-term, high-reliability service in midstream and transmission infrastructure.

  • Buried Natural Gas Transmission Pipelines: Provide leak-free, maintenance-free isolation with a fully welded body ideal for underground installation.
  • Compressor and Pump Stations: Deliver robust shut-off and vibration-resistant performance in high-pressure boosting systems.
  • Block Valve Stations: Offer secure sectional isolation in long-distance pipelines with minimal external exposure and reduced maintenance needs.
  • Metering and Regulator Stations: Maintain high sealing integrity and pressure containment at key flow control and measurement points.
