2″ Carbon Steel Ball Valve | Durable & High-Pressure Shut-Off

Description

2-Inch Carbon Steel Ball Valve – Product Overview

The 2-inch carbon steel ball valve (DN50) is a commonly used component in industrial piping systems. Manufactured with a high-quality carbon steel body, it offers exceptional mechanical strength and fatigue resistance, enabling it to withstand high pressure, high temperature, and severe thermal cycling.

The spherical closure member can be rotated 90 degrees to quickly shut off or open the media flow, providing convenient operation and rapid switching.

Compared with gate valves or globe valves, the carbon steel ball valve delivers greater flow capacity and lower flow resistance at the same nominal size, making it an ideal process control and isolation device.

Advantages & Features of the 2″ Carbon Steel Ball Valve

1. Compliant with A216 WCB Material Standard
The valve body material strictly adheres to ASTM A216 standard, Grade WCB – the American specification for high‑temperature cast steel components. The design of the a216 wcb carbon steel floating ball valve ensures structural integrity and corrosion resistance under high‑temperature and high‑pressure conditions, making it a preferred material for piping systems in petrochemical and power generation industries.

2. Fire‑Safe Design
Our 2‑inch carbon steel ball valve has passed API 607/6FA fire‑test requirements and holds fire safe carbon steel ball valve certification. Even in the extreme event of a fire that causes the soft sealing material to fail, the valve’s metal‑to‑metal secondary sealing structure effectively prevents media leakage, minimising fire‑related risks and providing a robust safeguard for personnel and assets.

3. Multiple Connection Types: Flanged and Threaded
To suit different piping system installation needs, the 2″ carbon steel ball valve is available in two mainstream connection options:

• Flanged connection: Raised‑face (RF) flanges conforming to ANSI/ASME B16.5. The flanged ball valve carbon steel design is suitable for large‑bore, high‑pressure applications, offering ease of installation and disassembly, high connection strength, and reliable sealing – a common choice in refinery and chemical plant piping systems.

• Threaded connection: NPT taper pipe threads conforming to ANSI/ASME B1.20.1. The threaded ball valve carbon steel design saves space, requires no welding or flange bolting, and enables quick installation – ideal for instrument lines, auxiliary systems, or space‑constrained working conditions.
