  Why Use a Ball Valve Versus a Globe Valve? June 22, 2025 Introduction In the world of industrial flow control, selecting the right valve type for a specific application is crucial for system efficiency, safety, and longevity. Ball valves and globe valves are two of the most commonly used valve types, each with distinct characteristics that make them suitable for different scenarios. This article explores the key differences between these valve types and provides guidance on when to choose one over the other. For more specialized valve solutions, visit  STV Valves . Ball Valves: Design and Operation Ball valves utilize a spherical disc (the ball) with a hole through the center. When the valve is open, the hole aligns with the flow path, allowing media to pass through. When rotated 90 degrees, the solid part of the ball blocks the flow path, effectively shutting off flow. These valves are operated by turning a handle that rotates the ball. Most ball valves are quarter-turn val...

  In-Depth Guide to ANSI 600 Gate Valves: Structure, Applications, and Selection Tips 1. Introduction to ANSI 600 Gate Valves Gate valves play a critical role in industrial piping systems, serving predominantly as isolation devices for fluid control. Among various classifications, the ANSI 600 gate valve stands out for its high pressure rating and dependable sealing performance. Following American National Standards Institute (ANSI) guidelines, the "600" designates a class able to withstand pressures up to 10 MPa (about 600 psi), supporting safe operation in challenging environments. From oil & gas processing to power generation and chemical plants, these valves help ensure the seamless functioning of essential industrial processes. 2. Understanding ANSI Standards and the 600 Rating The ANSI standards underpin the design, production, and performance parameters for industrial valves in both the U.S. and internationally. For the gate valve, ANSI 600 specifies crucial requi...
