In industrial piping systems, valve selection directly impacts system performance, maintenance, and project cost.
While gate valves are often used for on/off flow control, globe valves offer distinct advantages that make them the preferred choice in many applications.
This article explores why engineers and procurement managers should consider globe valves over gate valves, highlighting technical features, performance benefits, and practical case studies.
Quick takeaway: Choose globe valves when precise flow control, throttling capability, and reliable shut-off are required, especially in process industries like chemical, water treatment, and power generation.
Gate valves are linear motion valves that use a wedge-shaped gate to start or stop flow.
They are ideal for full open or full close applications but are limited in precise flow regulation.
Globe valves, in contrast, have a spherical body and a movable plug or disc perpendicular to the flow path, allowing fine control over flow rate.
According to ASME B16.34 standards, globe valves offer superior sealing and throttling performance, making them suitable for high-pressure, high-temperature, and corrosive applications.
Globe valve vs gate valve: flow path and internal structure comparison
Engineer’s tip: Always review the valve’s flow coefficient (Cv) to ensure the correct sizing for precise flow control.
A globe valve regulates flow using a disc that moves perpendicular to the seat.
The disc is attached to a stem that passes through a threaded yoke or packing box. Turning the handwheel or actuator raises or lowers the disc, controlling the flow rate.
Many globe valves feature split body, bolted bonnet designs for easy maintenance and stainless steel or bronze seating for durability.
Procurement tip: Ensure proper packing and stem design to minimize leakage and maintain long-term reliability.
Example: A chemical plant replaced several gate valves with globe valves on a throttling line, achieving accurate flow control and reducing downstream pump cavitation by 15%.
Case insight: In a wastewater treatment plant, globe valves replaced gate valves on recirculation loops, improving flow accuracy and reducing energy costs by 10%.
Globe valves are commonly made from carbon steel, stainless steel (304/316), depending on pressure, temperature, and media.
Seat materials vary between metal (for high temperature/pressure) and soft elastomers (for chemical compatibility).
Body types include straight-through, angle, and three-way designs for specific piping configurations.
Expert tip: Select body and seat material that meets CE, ISO, or API standards for compliance and reliability.
Engineering tip: Proper valve alignment and torque settings prevent premature wear and ensure consistent performance.
When choosing between globe and gate valves, consider:
Procurement reminder: Always evaluate pressure rating, temperature limits, material compatibility, and valve sizing according to ASME/ANSI or ISO standards.
A refinery upgraded its chemical feed lines from gate valves to globe valves. The outcome:
Lesson learned: selecting the right valve for throttlin
