Lift check valve is a flange‑type automatic non‑return valve. Its disc moves up and down along the internal guide sleeve. Forward medium pressure lifts the disc for flow, while backflow pushes the disc down by self‑weight and reverse pressure to stop backflow without external actuation.
Available with EPDM soft‑seat or metal hard‑seat for different working conditions such as water, steam and oil products. It has relatively higher flow resistance and is preferably installed in horizontal pipelines. Widely used in water supply & drainage, fire‑fighting, steam and oil pipelines to protect pumps and equipment. Install strictly following the flow arrow on the valve body.
