Cast Steel Ball Valves for Reliable Pipeline Isolation

The Cast Steel Trunnion Mounted Ball Valve is designed for reliable shut-off and flow control in industrial pipeline systems. Its cast steel body provides structural strength, while the trunnion-mounted ball design offers stable support and helps reduce operating torque under suitable pressure conditions. It is widely applicable to oil and gas, petrochemical, power generation, and other industrial services.

Technical Specifications

  • Body Material: Cast carbon steel, stainless steel, or alloy steel, depending on model

  • Nominal Size: 2"–48" (DN50–DN1200), subject to design availability

  • Pressure Rating: ASME Class 150–2500, depending on model

  • Temperature Range: Determined by body material and seat configuration

  • Connection Types: Flanged or butt-weld ends

  • Ball Support: Trunnion-mounted structure

  • Seat Options: Soft-seated or metal-seated configurations, depending on application

  • Operation: Manual, gearbox, pneumatic, or electric

  • Design Standards: API 6D and ASME B16.34, subject to product configuration

  • Applications: Oil and gas pipelines, petrochemical plants, power stations, and industrial fluid systems

Custom materials, connection dimensions, actuation methods, and inspection requirements can be discussed according to project specifications. Final parameters are subject to model confirmation.
