English Version

American Standard Butt Weld Lift Check Valve is designed in accordance with ASME B16.34, with butt weld end connection and CF8 stainless steel body. The disc opens and closes automatically by medium pressure. It opens for forward flow and closes immediately to prevent backflow when the pressure drops, protecting pumps, compressors and other upstream equipment. With smooth flow passage, reliable sealing and compact structure, it features good erosion resistance. Suitable for high temperature and high pressure service, widely used in oil, gas, chemical and power station steam pipelines for unidirectional flow control.
