Globe Valve vs Check Valve: Key Differences and Selection Guide
In industries such as petrochemical, power, and others, the selection of pipeline valves directly impacts the operational efficiency of systems. As two major types of valves, how should we choose between globe valve vs check valve? This article will delve into the core differences between the two.
Globe Valve vs Check Valve: Significant Structural Design Differences
The globe valve features a spherical valve body design. The valve stem, which moves vertically, controls the opening of the valve disc, allowing for precise flow regulation. Its unique "Z"-shaped flow path results in a pressure drop of 15-20%, but it provides excellent sealing performance with a leakage rate of less than 0.01%.
In contrast, the check valve has a simpler structure, relying on fluid pressure to automatically open and close the valve disc. The typical pressure drop is only 5-8%, but there may be slight leakage at low flow rates.
Applications of Globe Valve vs Check Valve
● Globe Valve Best Uses:
- Steam systems that require flow adjustment
- Metering and control in chemical production
- Transport of high-pressure, high-temperature media
● Check Valve Best Uses:
- Backflow prevention at pump outlets
- Contamination prevention in water supply systems
- Compressed air pipelines
Globe Valve vs Check Valve: Valve Selection Recommendations
For operating conditions that require frequent flow adjustments, the globe valve should be prioritized. However, in unmanned pump stations and other places, check valves, which operate automatically, are more reliable. The newly developed rising check valve combines the advantages of both and has been successfully applied in several large-scale projects.
By understanding the difference between globe valve and check valve and their respective applications, one can make an informed valve selection for industrial pipeline systems.
