  • Advantages of Globe valves in Process Control

    Globe valves offer numerous advantages when used in process control applications. They provide excellent throttling control, making them ideal for applications where precise flow control is required. They also have a compact design, making them an ideal solution where space is limited. With a low-pressure drop across the valve, they effectively reduce energy consumption and increase efficiency. They are also highly resistant to corrosion, enabling them to withstand use in harsh environments. Lastly, globe valves are available in a wide range of sizes, materials, and end connections, making them suitable for various applications. 
     
  • Applications of Globe Valves

    Globe valves are used in a range of different industries, and are particularly valued for their flow control capabilities. In the petrochemical industry, they are used for controlling the flow of fluids in pipelines, such as crude oil, refined products, and gases. They are also used in processing plants for regulating the flow of chemicals and maintaining accurate pressure control. In abattoirs, they are used for regulating the flow of water, steam, and chemicals used in the cleaning, sterilisation, and processing of animal products. In bulk terminals, they are used for loading and unloading liquid and gas cargo from tankers, railcars, and storage tanks. Globe valves are also commonly used in water treatment, power generation, and HVAC systems, where precise flow control and pressure regulation is necessary. They are also commonly used as isolation valves.
     
  • How do Globe Valves Work?

    Globe valves are linear motion valves designed to regulate the flow of fluids. The valve body has a spherical shape, and the disk or plug inside the valve moves up and down in a linear motion to control the flow of fluid. The disk is attached to a valve stem that is operated by a hand wheel or an actuator. When the valve is in the open position, the fluid flows through the valve body, passing around the disk. When the valve is partially or fully closed, the disk moves down, creating a narrower passage for the fluid to flow through. Globe valves provide superior throttling control due to their design and can regulate the flow of fluid accurately. Globe valves are used in a wide range of applications, including HVAC systems, water treatment plants, and the oil and gas industry, where precise flow control is critical to the process.
     
  • What are the main differences between a globe valve & a butterfly valve

    The main differences between globe valves and butterfly valves include design and application aspects. Globe valves are linear motion valves that use a disk (shaped like the bottom of a globe) to regulate the flow of fluid. This disk moves up and down in a linear motion to control the flow, allowing for precise throttling control. As aforementioned, they are commonly used in the oil and gas industry, steam applications and in water treatment plants. Butterfly valves, on the other hand, are rotary valves that use a disk-shaped closure element to isolate the flow of air and fluid. The disk rotates around an axis perpendicular to the flow, allowing for quick and easy opening and closing. Butterfly valves are commonly used in HVAC systems or water distribution systems.
