Ductile Iron Flange Ball Check Valve Q41X-10Q

Q41X-10Q ductile iron ball check valve is a flange mounted non-return valve with internal free-floating rubber-coated ball. Forward medium pressure lifts the ball away from the valve seat to open flow path; when fluid reverses, back pressure pushes the rubber ball tightly against seat bore to shut pipeline automatically and avoid reverse flow damage to pumps and equipment. QT450 ductile iron body brings superior toughness vs ordinary cast iron, anti-cracking under pipeline water hammer, widely used in general water & wastewater pipelines.

304/316 Stainless Steel Flange Swing Check Valve H44W-16P

H44W-16P stainless steel swing check valve is a flange-type one-way flow control valve designed for corrosive industrial pipelines. It adopts a swing disc structure that opens freely by forward fluid pressure and closes instantly by backflow pressure and disc gravity to prevent reverse flow. With full stainless steel 304 / 316 material and metal hard seal design, this valve delivers excellent anti-corrosion, high temperature resistance and zero-leakage performance, far more durable than cast iron check valves.

WCB Cast Steel Flange Lift Check Valve H41H-16C

H41H-16C Flange Lift Check Valve is a heavy-duty carbon steel metal hard-seal check valve designed for industrial pipeline systems. Adopting vertical lift structure and flange connection, this valve automatically controls unidirectional medium flow and effectively prevents fluid backflow, pipeline reverse pressure, and equipment damage. Manufactured in full compliance with national industrial standards, it features stable pressure resistance, high temperature to
