3 Piece Ball Valve is a high-performance industrial valve designed with a three-piece body construction, allowing in-line maintenance and easy replacement of seals and internal components without removing the pipeline. It features a full bore or reduced bore design for optimal flow efficiency and low pressure drop. The valve operates with a quarter-turn mechanism for fast and reliable shut-off. Equipped with PTFE or metal-seated sealing, it ensures excellent bi-directional sealing performance, high durability, and resistance to pressure and temperature. Widely used in oil & gas, chemical, petrochemical, and industrial process systems, it delivers long service life and dependable flow control under demanding conditions.

Features & Advantages – 3 Piece Ball Valve
Three-piece split body design
Allows easy in-line maintenance, enabling quick replacement of seats, seals, and internal components without removing the valve from the pipeline.
Reduced downtime & maintenance cost
Modular construction significantly lowers maintenance time and operational shutdown costs, ideal for continuous process industries.
Full bore / reduced bore options
Ensures high flow capacity with minimal pressure drop in full bore design, improving system efficiency.
Superior sealing performance
Advanced PTFE, RPTFE, or metal seat options provide tight bi-directional sealing with zero-leakage performance under high pressure.
High pressure & temperature resistance
Engineered for demanding applications, suitable for Class 150–2500 and extreme temperature conditions depending on materials.
Blow-out proof stem design
Enhances operational safety by preventing stem ejection under internal pressure.
Fire-safe & anti-static optional design
Complies with API 607/API 6FA fire-safe standards and includes anti-static devices for hazardous environments.
Flexible actuation options
Compatible with lever, gear, pneumatic, and electric actuators for automated or manual control systems.
Wide industrial applicability
Widely used in oil & gas, petrochemical, chemical processing, power generation, water treatment, and general industrial pipelines.
