DELCO H41F46 Lined Check Valve (Lift Type), PFA/FEP Lined, WCB Body, PN16/Class 150
DELCO H41F46 lined check valve features a lift-type design with a robust WCB cast steel body fully lined with corrosion-resistant PFA, FEP, or PTFE. It is engineered to prevent backflow in severe chemical service, effectively handling acids, alkalis, and other aggressive media without metallic contact.
Size Range: DN15-DN500
Material: WCB, Stainless Steel etc.
Flange Standard: GB / ANSI /DIN /JIS etc.
Features
Fully lined lift check valve for maximum corrosion resistance—prevents backflow in harsh chemical lines.
✅Superior corrosion resistance: The thick molded lining (PFA/FEP/PTFE) isolates the body from the media, ensuring long service life in acid/alkali applications.
✅Reliable backflow prevention: The lift-type disc responds quickly to reverse flow, protecting upstream equipment like pumps and instruments.
✅Zero metal-to-media contact: Media only touches the fluoropolymer lining, making it safe for high-purity and aggressive chemical processes.
✅Robust WCB body armor: The cast steel outer shell provides the mechanical strength and pressure rating (PN16) needed for industrial piping.
✅Complete lined valve solution: Works seamlessly downstream of a (lined ball valve) for isolation and pairs well with a (lined strainer) to protect the check valve seat from debris.
