Stainless steel H41 Flange Check valve PN10/PN16 SS304

This H41 lift check valve is precision cast from  with flange connection. As a common vertical lift check valve, it relies on medium pressure to lift the valve disc for smooth medium forward flow; once fluid reverses, the disc will drop rapidly relying on gravity and backflow pressure to tightly seal the valve port, cutting off reverse flow instantly. It is widely used to prevent liquid/gas backflow, protecting pumps, compressors and pipeline equipment from reflux impact damage.
