The Two-Piece Flanged Ball Valve is a rugged, industry-standard solution for reliable fluid isolation. Designed with a split-body construction consisting of a main body and a cap, this valve provides a robust, leak-proof connection for a wide range of industrial media. Unlike three-piece valves, the two-piece design minimizes potential leak paths by reducing the number of body joints, making it a preferred choice for high-integrity piping systems.
Available in ANSI Class 150 for general industrial service and ANSI Class 300 for high-pressure applications, these valves are engineered to meet the stringent demands of modern process industries.
Key Features & Benefits:-
- Reduced Leak Paths: The split-body design features only one body joint, significantly increasing safety and structural integrity compared to multi-piece valves.
- Full Bore (Full Port) Design: Ensures the internal diameter of the valve matches the pipe, resulting in zero flow restriction and a minimal pressure drop.
- Floating Ball Technology: The precision-machined ball moves slightly against the downstream seat under pressure, ensuring a bubble-tight seal even at low pressures.
- Blow-out Proof Stem: Engineered with an internally inserted stem that cannot be ejected by system pressure, providing an essential safety barrier for operators.
- ISO 5211 Actuator Mounting: Equipped with a standardized top flange, allowing for the direct mounting of pneumatic or electric actuators without the need for expensive brackets or couplings.
- Fire-Safe & Anti-Static: Designed to meet API 607 standards, ensuring the valve remains functional during a fire, with anti-static devices to prevent electrical discharge.

Target Industrial Applications:-
The Two-Piece Flanged Ball Valve is the workhorse of heavy-duty process control:
- Oil & Gas Refining: Ideal for hydrocarbon processing, fuel storage, and distribution lines.
- Chemical Processing: Reliable isolation for acids, solvents, and aggressive chemical reagents.
- Water & Wastewater: Used in high-pressure pumping stations and water treatment facilities.
- Steam & Utilities: Perfect for saturated steam lines and condensate return systems.
- Pulp & Paper: Handling corrosive liquors and chemical additives in manufacturing.
Why Choose the Two-Piece Flanged Design?
The Two-Piece Flanged Ball Valve offers the perfect balance between durability and cost-efficiency. Its rigid body construction is better suited for high-torque applications and heavy-duty piping stresses than threaded alternatives. By choosing a flanged design, you ensure a secure metal-to-metal connection that is easier to inspect and replace during scheduled maintenance shutdowns.
