Welded ball valve

Product Overview

The 3-piece butt welded ball valve is a high-performance valve designed for demanding industrial applications requiring secure and durable pipeline connections. Featuring a three-piece body construction, this valve provides excellent maintainability and sealing performance. 、
The butt-welded connection ensures a permanent, leak-proof joint, making it ideal for high-pressure, high-temperature, and critical fluid control applications. Its compact design, superior durability, and ability to handle aggressive and high-temperature media make it suitable for a wide range of industries, including petrochemical, oil and gas, power generation, and chemical processing.

Key Features

Three-Piece Construction Simplifies maintenance by allowing easy disassembly without removing the valve body from the pipeline. Reduces downtime and operational costs in maintenance-intensive applications.
Butt-Welded Connection Provides a secure, permanent joint for enhanced leak-proof integrity. Eliminates potential leakage associated with threaded or flanged connections. Suitable for applications involving vibration, thermal expansion, or contraction
Flow Efficiency Full-port design minimizes pressure drop and ensures unrestricted flow, making it suitable for applications where flow efficiency is critical.
Fire-Safe and Anti-Static Design Meets fire-safe standards (API 607/ISO 10497) for reliable operation in fire-prone environments. Anti-static device ensures safety when handling flammable or explosive media.
Flexible Actuation Manual operation via heavy-duty lever or gear. Automation-ready with pneumatic, hydraulic, or electric actuators.

Advantages Compared to Other Valve Types

Secure Connection
The butt-welded joint eliminates the risk of leakage, outperforming flanged and threaded connections in high-pressure and high-temperature applications.
Enhanced Durability
Suitable for environments with vibration, thermal cycling, or corrosive media, offering a longer service life compared to other connection types.
Compact and Maintainable Design
The three-piece body design ensures that internal components can be serviced or replaced without removing the valve from the pipeline, reducing maintenance downtime.
Flow Efficiency
Full-port design minimizes pressure loss, which is a significant advantage over other valve types like globe valves.
Versatility
Can handle various media, including corrosive chemicals, high-temperature steam, and hydrocarbons, unlike butterfly or check valves that may have limitations with certain media.
