Product Description

The Q347F-16C WCB Cast Steel Large Bore Pipeline Ball Valve is specifically engineered to meet the rigorous demands of industrial fluid control systems. Designed with a robust trunnion-mounted ball and a highly responsive worm gear operator, this valve provides exceptional stability, precise flow regulation, and reliable shut-off capabilities in large-scale pipeline networks. The utilization of premium WCB cast steel ensures outstanding structural integrity and long-term durability, making it an optimal choice for complex environments where operational safety and consistent performance are critical evaluation factors for procurement engineers.

Chief Features

Evaluating the core structural characteristics is essential for minimizing maintenance downtime and mitigating operational risks. The Q347F-16C series integrates several advanced design elements tailored for heavy-duty applications, ensuring long-term reliability and secure fluid management.

1. BOLTED BONNET: Enhances the overall structural strength of the valve body and significantly simplifies internal maintenance and inspection procedures. 

2. BLOW OUT PROOF STEM: A critical safety feature designed to prevent stem ejection under high-pressure conditions, ensuring secure operation and protecting personnel.

3. STRUCTURE IMPROVE ON API: Engineered to meet and exceed rigorous industry standards, providing reliable performance for demanding pipeline projects.

4. OPENING AND CLOSING POSITION: Features clear visual indicators for precise flow control, reducing the risk of operator error during manual adjustments.

5. AVAILABLE WITH WORMGEAR OPERATOR: Facilitates smooth, controlled operation for large bore sizes, significantly reducing the required operating torque and improving efficiency.

6. FLANGED ENDS: Ensures secure, stable, and leak-free connections within existing pipeline infrastructure, simplifying the installation process.

7. BUTT-WELDING ENDS FULL PORT, FLOATING OR TRUNNION MOUNTED TYPE: Offers versatile design configurations to accommodate specific flow requirements, minimizing pressure drop and optimizing system performance.

Technical Specifications & Material Composition

Compliance with recognized international standards is a fundamental requirement for industrial project integration. The technical specifications detailed below outline the comprehensive design, testing, and manufacturing criteria of the valve, including strict adherence to GB/T, API, and ASME protocols. Furthermore, material selection directly influences the lifespan and reliability of pipeline components. The Q347F-16C series utilizes high-grade WCB cast steel for the main body and robust stainless steel alloys (such as 20Cr13 and A182-F304) for critical internal parts. This carefully engineered material composition provides excellent resistance to mechanical stress, thermal variations, and corrosive media.

Main External and Connection Dimension

Accurate dimensional planning is vital for successful pipeline installation and system upgrades. The main external and connection dimensions provided in the subsequent section offer engineers and procurement specialists the precise data required to evaluate spatial constraints. By consulting these dimension drawings, project managers can ensure a proper fit with flanged or butt-welding ends, thereby reducing installation risks and optimizing the overall efficiency of the fluid control system.
