This stainless steel threaded gate valve is designed and manufactured in compliance with both National Standard and ASME ANSI standards, with its main body precision-cast from high-quality 304 or 316 stainless steel. Equipped with standard female threaded connections (NPT/BSPT), it is a straight-through on-off industrial valve mainly used for full open and full close shut-off control of various fluid pipelines, not suitable for throttling regulation, serving as a core on-off equipment for small and medium-sized low-pressure fluid pipeline systems.
