A Practical Guide for High-Pressure and Large-Bore Applications In industries such as oil & gas, petrochemicals, LNG, and power generation, selecting the right valve is critical to system performance and safety. When dealing with high pressures, large pipe diameters, or demanding service conditions, the trunnion-mounted ball valve is a preferred choice for many engineers and plant operators.   🔧 Trunnion vs. Floating Ball Valves – What’s the Difference? Ball valves typically fall into two categories: floating and trunnion-mounted. •In a floating ball valve, the ball is held in place by the compression of the seats. It moves slightly to maintain a seal—best suited for low- to medium-pressure systems. •In a trunnion-mounted ball valve, the ball is fixed in position by support shafts (trunnions) on both the top and bottom. The seats move toward the ball to create a seal. This structural difference gives trunnion valves a few key advantages.   ✅ Why Choose a Trunnion-Mounted Ball Valve? Benefit Explanation Low operating torque Reduced friction allows smoother actuation and smaller actuators. Longer seat life The fixed ball minimizes wear, especially under high pressure. Better performance in large sizes Ideal for high-DN and high-pressure systems. Bidirectional sealing Some designs offer effective sealing from both flow directions.   🌍 Common Applications Because of their robust design, trunnion ball valves are widely used in: •Oil and gas transmission pipelines •LNG terminals and cryogenic service •Petrochemical plant process lines •High-pressure steam or condensate systems •Isolation valves in safety-critical operations They are often specified when tight shutoff, long service life, and system reliability are essential.   🛠 Configurations and Custom Options Trunnion-mounted ball valves come in many configurations. Key variables include: •Materials: carbon steel, stainless steel, duplex, Inconel, etc. •Seat design: soft-seated, metal-seated, double block & bleed •End connections: flanged, welded •Actuation: manual, pneumatic, or electric •Applicable Standard: May include API 6D, ISO 5211, API 607 (firesafe), and others Suppliers may also offer custom engineering to meet specific standards or performance needs.   🔍 What to Consider When Sourcing If you're planning to specify or source a trunnion ball valve, consider the following: •Operating pressure and temperature •Media type (corrosive, toxic, flammable, etc.) •Flow direction and shutoff requirements •Space constraints for actuator or access •Certification or end-user specifications Working with a knowledgeable supplier ensures that the valve you choose is optimized for your system—and not just “fitted to size.”   💬 Need Help Selecting the Right Trunnion Valve?

In industries where safety and reliability are paramount—such as oil & gas, chemical processing, and power generation—ball valves play a crucial role in flow control systems. One often overlooked yet vital feature in high-performance ball valves is anti-static design. As industry demands continue to evolve with stricter safety standards and higher performance expectations, anti-static features are becoming a baseline requirement—especially for valves used in flammable or hazardous environments. Why Anti-Static Design Matters Ball valves operate by rotating a metal or ceramic ball within a sealed chamber to control the flow of liquids or gases. During this rotation, friction between the ball, seat, and stem can generate static electricity. In volatile environments, even a minor spark could ignite flammable gases or vapors—posing serious risks to personnel, equipment, and the environment. An anti-static design ensures that any static electricity generated within the valve body is safely discharged. This is typically achieved by incorporating conductive materials such as spring-loaded grounding devices or graphite grounding paths, which create a direct electrical connection between the ball and the stem, and from the stem to the body. Our Commitment to Safety and Performance At Anson Flow Corp., we understand the importance of integrating safety into every detail of our products. That’s why all of our firesafe and metal seat ball valves are designed with built-in anti-static protection. 🔥 Firesafe Ball Valves: Certified to API 607 and other international standards, our firesafe series are engineered to maintain sealing integrity even in extreme fire conditions.

This makes them suitable for demanding applications where safety and longevity are non-negotiable. Meeting Evolving Industry Demands As regulatory bodies continue to raise the bar on safety and performance, anti-static design is no longer a value-added feature—it's a necessity. Our valves are engineered not just to meet today's standards, but to anticipate tomorrow's requirements. From the materials we select to the testing protocols we follow, every detail reflects our commitment to quality, safety, and innovation. Conclusion Anti-static design in ball valves is a small but essential component of modern industrial safety.

In demanding industrial applications, selecting the right valve can directly impact operational efficiency, maintenance costs, and system downtime. Among the various ball valve configurations, the three-piece ball valve design stands out for its superior serviceability, long-term cost benefits, and versatile functionality. In this article, we explore how the three-piece design works, its advantages, and why it's a preferred solution across numerous industries.   What Is a Three-Piece Ball Valve? A three-piece ball valve consists of three main components: •     A central body containing the ball and seats •     Two end caps (body connectors) that are bolted or clamped to the center section This modular design enables easy disassembly of the valve body without removing the end connections from the pipeline. The valve can remain in-line while internal components are accessed for maintenance or replacement.   Key Advantages of the Three-Piece Design 1. Easy Maintenance & Minimal Downtime One of the most notable benefits is in-line serviceability. Technicians can quickly remove the center section for cleaning, seat and seal replacement, or ball inspection—without disturbing pipe alignment. This significantly reduces downtime and avoids production disruption. 2. Lower Long-Term Costs While the initial cost of a three-piece ball valve may be higher than a one- or two-piece valve, the ability to replace only worn components extends the valve’s life and minimizes full replacement costs over time. This is particularly beneficial for high-cycle or corrosive environments. 3. Flexible Installation & Repair Because the end caps remain fixed, it's easier to maintain consistent pipeline positioning and alignment. This is ideal for systems requiring frequent maintenance, such as in: •     Petrochemical plants •     Food and beverage processing •     Pharmaceutical manufacturing •     Water and wastewater systems 4. Customizable Materials and Ends Three-piece valves are available with customizable end connections (threaded, welded, flanged) and a variety of body and seat materials to suit different media and temperatures.   When to Choose a Three-Piece Ball Valve A three-piece ball valve is an excellent choice when: •     Your system requires frequent cleaning or maintenance •     You operate in abrasive or corrosive environments •     Downtime and labor costs need to be minimized •     You want a long-lasting valve that supports replaceable part   Anson Flow’s Three-Piece Ball Valve Capabilities At Anson Flow Corp., we supply precision-engineered three-piece ball valves built to perform under demanding conditions.
