Screwed Globe Valve

Product Name & Standards Screwed Globe ValveCompliant with API 600, ASME B16.34, and ANSI B16.11 standards. Core Definition A 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. – Operating Temperature: -29℃ – 425℃ (carbon steel body) / -196℃ – 550℃ (stainless steel body). – Body Materials: Carbon Steel (A105), Stainless Steel (304L/316L), Brass (ASTM B16). – Valve Plug Material: Stainless Steel (304L/316L), Brass (for low-pressure applications), Alloy Steel (for high-temperature/high-pressure use). – Sealing Material: PTFE (Polytetrafluoroethylene), Metal-to-Metal sealing – ensures chemical resistance and tight shut-off. – Connection Type: Screwed (NPT/BSPP) – compatible with standard threaded pipelines. – Size Range: 1/4″ – 2″ (common threaded sizes for general-purpose flow control). 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.
