Globe Valve Technical Features in Industrial Fluid Control
In the field of industrial fluid control, globe valves play a pivotal role due to their excellent regulating performance. How do these valves achieve precise flow control? Let's break down their technical features.
Unique Structural Design
The core of the working principle of globe valve lies in its stem-disc mechanism. When the handwheel rotates, the stem drives the disc to move vertically, continuously adjusting the cross-sectional area of the flow path in conjunction with the valve seat. This design enables flow control precision of up to ±2%, far surpassing other valve types.
Five Key Technical Advantages
● Bidirectional Sealing Ability
The specially designed valve seat can withstand high pressure valve applications, offering bidirectional pressure resistance.
● High-Temperature Adaptability
Made of stainless steel, it can withstand temperatures up to 250°C (customized).
● Precise Throttling
The linear flow control characteristic curve ensures consistent regulation.
● Low Leakage Rate
The metal hard seal provides a leakage level that meets ANSI V standards.
● Ease of Maintenance
Most models support online maintenance, minimizing downtime.
Industry Application Examples
Chemical Plant Case: After installing a globe valve in the sulfuric acid pipeline, flow control precision was improved by 40%, saving over 500,000 yuan annually.
Power Plant Case: In the main steam system, a specially designed bellows-sealed globe valve has been running continuously for 5 years without any leakage, showcasing its robust performance under 10K-100K Low conditions.
This analysis underscores how the globe valve, with its unique design and technical advantages, contributes significantly to both flow control and high pressure valve applications across industries.
