DELCO H42W Vertical Lift Check Valve, Flanged, Stainless Steel (CF8/CF8M) or WCB, DN15–DN250
The DELCO H42W Vertical Lift Check Valve is specifically designed for vertical pipelines with upward flow. It features a spring-assisted or gravity-operated disc that opens with forward flow and closes instantly when flow stops, effectively preventing backflow and protecting pumps in water supply and industrial applications.
Size Range: DN15-DN500
Material: WCB, Stainless Steel etc.
Flange Standard: GB / ANSI /DIN /JIS etc.
Features
Vertical-mount check valve for upward flow—quick closing to prevent backflow and water hammer in pump lines.
✅Dedicated vertical installation: Designed strictly for vertical pipes with bottom-to-top flow, ensuring the disc aligns perfectly with gravity for reliable sealing.
✅Quick-closing action: The lift-type disc travels a short distance and reseats instantly when flow stops, minimizing water hammer risk compared to swing types.
✅Robust guided disc: The internal guide ensures the disc moves smoothly without tilting or jamming, even under high flow velocities.
✅Wide material options: Available in WCB for general service and CF8/CF8M stainless steel for corrosive or clean water applications (as shown in the image).
✅Pump protection partner: Ideally installed directly above a (submersible pump) or booster pump to prevent backspin, and often paired with a (gate valve) for isolation during maintenance.
