Key Features
Linear Motion Control
The rising stem and disc structure provides accurate valve positioning, allowing reliable shut-off and controlled throttling performance in industrial pipeline systems.
Precision Sealing Structure
Precision-machined disc and seat surfaces provide consistent sealing contact and help reduce leakage during operation under specified working conditions.
Robust Body and Bonnet Design
The valve body and bolted bonnet structure are designed for industrial service conditions, allowing convenient inspection and maintenance of internal components.
Reliable Stem and Disc Connection
The stem and disc connection design ensures smooth operation, reliable movement, and long-term mechanical stability during repeated valve cycles.
Working Principle
Industrial Globe Valve controls fluid flow by adjusting the opening between the disc and seat through linear movement of the closing element.
Step 1: Opening Adjustment
The disc position changes to increase or reduce the flow passage, controlling the amount of fluid passing through the valve.
Step 2: Flow Regulation
During partial opening, the valve adjusts flow rate by creating controlled resistance within the flow path, making it suitable for throttling applications.
Step 3: Shut-off Operation
When fully closed, the disc contacts the seat to block the flow passage and isolate the pipeline.

FAQ
Q: What are the advantages of using a globe valve for flow control?
A: Globe valves provide precise throttling control because the linear disc movement allows accurate adjustment of flow rate compared with valves mainly designed for isolation.
Q: Can a globe valve be installed in any pipeline orientation?
A: Globe valves can be installed in different pipeline orientations depending on design requirements, but installation direction and stem position should follow manufacturer recommendations.
Q: What is the difference between straight pattern, angle, and Y-type globe valves?
A: Straight pattern globe valves are commonly used for general pipeline service, angle globe valves help simplify piping layouts, and Y-type globe valves provide lower pressure drop.
Q: How does a globe valve handle high-pressure and high-temperature applications?
A: High-pressure and high-temperature globe valves require suitable body materials, trim selection, pressure class, and sealing design based on operating conditions and media compatibility.
Q: Why does a globe valve have higher pressure loss compared with a gate valve?
A: A globe valve has higher pressure loss because the fluid changes direction through the valve body to achieve better flow control performance.
Q: How often should an industrial globe valve be maintained?
A: Maintenance frequency depends on operating conditions, media characteristics, service temperature, pressure cycles, and manufacturer recommendations.
Q: What causes globe valve leakage during operation?
A: Globe valve leakage may result from seat damage, improper installation, unsuitable material selection, excessive wear, or operating conditions beyond design limits.
Q: Are globe valves suitable for frequent operation?
A: Yes, globe valves are suitable for frequent operation because their linear motion design allows controlled opening, closing, and flow adjustment.
Q: What factors affect the service life of a globe valve?
A: Globe valve service life depends on material selection, operating conditions, media characteristics, sealing performance, maintenance practices, and correct valve sizing.
Q: What information is required for a globe valve quotation?
A: Required information normally includes valve size, pressure rating, medium, temperature, connection type, operation method, and project requirements.
