What are the advantages of Globe valves? - China Valve Factory
Key Advantages of Globe Valve:
1. Excellent Sealing Performance and Low Leakage: The valve disc and seat form a hard seal, with controllable clamping force and tight shut-off. Leakage under high pressure is significantly less than that of gate valves, making it suitable for zero-leakage applications.
2. Precise Flow and Pressure Regulation: Short opening and closing strokes allow for precise control of the flow cross-sectional area, resulting in stable throttling and pressure regulation. Commonly used in pipelines requiring flow regulation.
3. Simple Structure and Easy Maintenance: The valve body, disc, and seat are separate, facilitating easy disassembly and assembly. Worn valve seats and sealing surfaces can be individually ground and replaced, eliminating the need for complete valve replacement and reducing maintenance costs.
4. Wide Range of Applicable Media: Suitable for steam, oil, water, acids and alkalis, oil and gas, and high-temperature and high-pressure applications. Excellent high-temperature and high-pressure resistance makes it widely used in power plants and chemical high-pressure pipelines.
5. Short Opening and Closing Stroke and Effortless Operation: Compared to the long-stroke opening and closing of gate valves, globe valves require only a small movement of the disc to fully open and close, making manual operation easier.
6. Easy to install actuators for automatic control: Short stroke, stable torque, compatible with electric and pneumatic actuators, stable automatic control, widely used in automated pipelines.
7. Erosion resistant and long service life: The sealing surface is not directly eroded by the medium when closed; the wear-resistant design under throttling conditions has a longer service life than ordinary gate valves.
Supplementary Applicable Scenarios:
Suitable for: Steam pipelines, water supply systems, chemical pressure regulating pipelines, high-pressure process pipelines;
Not suitable for: Large-diameter, high-flow media, media containing a large amount of solid particles.
