Forged Steel Ball Valve
Forged Steel Ball Valves
Forged steel ball valves use a quarter-turn ball mechanism to start or stop fluid flow in industrial piping systems. Selection depends on operating pressure, temperature, process media, sealing requirements, and applicable design standards.
Product Overview
Forged Steel Body
Available in specified forged carbon steel, alloy steel, or stainless steel grades, subject to the valve design.
Quarter-Turn Operation
Supports manual operation or pneumatic/electric actuation, depending on configuration.
Flexible Sealing Options
Soft-seated or metal-seated designs can be selected according to media, temperature, and shutoff requirements.
Application-Specific Configuration
Bore type, body design, pressure class, and end connections can be specified during RFQ review.
Key Features & Design Options
Body Construction
One-piece, two-piece, or three-piece designs, subject to the available product range and pressure requirements.
Ball & Stem Assembly
Ball geometry, stem design, and sealing components are selected according to operating torque, pressure, and service conditions.
Full Bore or Reduced Bore
Full-bore designs provide a flow passage close to the connecting pipe diameter; reduced-bore designs use a smaller passage where permitted by the process requirements.
Optional Safety Features
Fire-tested construction, anti-static devices, anti-blowout stems, and lockable handles are available only on applicable models.
