Trunnion and Floating Ball Valves – A Technological Overview
Trunnion and floating ball valves are vital components in modern industrial piping systems, designed to regulate the flow of liquids, gases, and slurries efficiently. These valves have gained prominence due to their durability, reliability, and ability to handle high-pressure and high-temperature applications. A floating ball valve features a movable ball that is held between two seats and moves slightly when the valve is closed, creating a tight seal. In contrast, a trunnion-mounted ball valve uses a shaft or trunnion to anchor the ball, reducing the torque needed to operate larger valves.
Technological advancements have improved these valves’ performance through materials like stainless steel, carbon steel, and high-performance alloys that resist corrosion and wear. Automation technologies, such as electric and pneumatic actuators, allow remote operation and integration with smart plant systems. Industries like oil & gas, chemical processing, and power generation heavily rely on these valves for flow control, minimizing downtime and enhancing safety.
FAQs:
Q1: What is the main difference between trunnion and floating ball valves?
A: Trunnion valves have a fixed ball supported by shafts, reducing operating torque, whereas floating valves have a ball that moves slightly to create a seal.
Q2: Where are these valves commonly used?
A: They are used in oil & gas, chemical plants, power plants, and other industrial pipelines.
Q3: Can these valves be automated?
A: Yes, they can be equipped with pneumatic or electric actuators for automated operations.
