Product Name & StandardsScrewed Globe ValveCompliant with API 600, ASME B16.34, and ANSI B16.11 standards.
Core DefinitionA specialized flow control valve featuring threaded connections, engineered to regulate, stop, or adjust the pressure of liquids or gases in pipelines. Renowned for exceptional reliability and tight shut-off performance, it serves as a versatile solution for precise flow regulation and pressure control in industrial, commercial, and residential systems.
Structure & Working Principle
- Key Components: Threaded valve body, disk-shaped valve plug, valve stem, and manual handwheel.
- Operating Mechanism: Rotating the handwheel drives the valve stem, lowering the disk-shaped plug to close the flow passage (shut-off) or adjusting its position to regulate flow rate and pressure. The threaded connection ensures secure integration with pipelines, while the precision-machined plug and valve seat deliver tight sealing.
- Connection Method: Screwed (NPT/BSPP) ends – compatible with standard threaded pipelines, enabling straightforward on-site installation without complex tools.
Performance Advantages
- Superior reliability: Robust construction and precision engineering ensure consistent performance in long-term operation.
- Tight shut-off capability: Precision-machined valve plug and seat form a leak-proof seal, eliminating unwanted leakage.
- Versatile functionality: Dual-purpose design supports both flow regulation (throttling) and pressure control, adapting to diverse process requirements.
- Wide compatibility: Available in various materials and sizes, suitable for a broad range of liquids, gases, and operating conditions.
- Intuitive operation: Manual handwheel control allows precise adjustment, facilitating easy flow and pressure management.
Key Specifications
- Pressure Rating: PN10 – PN250 / Class 150 – 1500.

Application Fields
- Industrial Systems: Oil & gas distribution, chemical processing auxiliary pipelines, power generation, and instrumentation lines requiring precise pressure/flow control.
- Commercial Infrastructure: Commercial building HVAC systems, municipal water/gas supply branches, compressed air lines, and fire protection auxiliary pipelines.
- Residential & General Use: Home water/gas lines, small-scale heating systems, and DIY plumbing projects needing reliable shut-off and flow regulation.
- Specialized Scenarios: Low-to-medium pressure pipelines, process systems requiring throttling control, and applications where tight shut-off and pressure stability are critical.
