Globe Valves
Stainless Steel American Standard Globe Valve
- Precision Structure, Reliable Sealing: The sealing surfaces of the disc and seat are overlaid with Stellite cobalt-based hard alloy, providing excellent resistance to wear, high temperatures, corrosion, and abrasion for a long service life.
- Optimized Stem Design: The valve stem is quenched, tempered, and surface-nitrided for superior corrosion and scratch resistance.
- Reliable Back-Seal Structure: Features a threaded stainless steel back-seal seat, allowing for safe and convenient online packing replacement without shutting down the line.
- Top-Entry Structure (Optional): Some designs permit online inspection and maintenance of internal components without removing the valve from the pipeline, significantly reducing maintenance costs.
- Single-Seat Safety Design: Effectively prevents abnormal pressure buildup in the valve cavity caused by factors like temperature fluctuations, ensuring safe system operation.
The Stainless Steel American Standard Globe Valve is an industrial valve designed and manufactured in compliance with American ASME and API standards. Its core structure features a plug-type disc that moves perpendicularly along the centerline of the valve seat to open or close the pipeline. This design ensures nearly frictionless contact between sealing surfaces during operation, significantly enhancing sealing reliability and service life. With a short stroke for rapid opening/closing and precise flow regulation capabilities, it is the ideal choice for reliable shut-off or throttling of high-temperature, high-pressure media in industries such as petroleum, chemical, and power generation.
