Check-All FPNTFMT.500SST 3" Teflon Flange Insert Check Valve 0.500 PSI - New

Check-All FPNTFMT.500SST 3" Teflon Flange Insert Check Valve 0.500 PSI - New Up for sale is a genuine, high-performance Check-All Valve fluid control component: a 3-inch Flange Insert Check Valve, model part number FPNTFMT.500SST (Size Code M ). Precision-engineered to demanding industrial standards, this specialized non-return valve features a 6.25-inch outer disc diameter designed to drop directly inside standard 3" ANSI Class 150 pipe flange bolt circles. It functions as a compact, self-activating safety mechanism that permits unrestricted fluid flow in one direction while providing immediate closure to prevent backflow. [1, 2] The assembly features an ultra-durable, corrosion-resistant 316 stainless steel trim constructionâincluding the central seat, cage, and internal spring guide. It relies on a high-strength spring calibrated to a low 0.500 PSI cracking pressure . The spring is fully encapsulated in premium, chemically inert FEP fluoropolymer sleeving to shield it from harsh process fluids. The heavy-duty structural outer body is molded from high-dielectric, pristine white Fluoropolymer (PTFE/Teflon) resin material, providing near-universal chemical resistance. This construction eliminates fluid contamination, making it ideal for high-purity chemical processing, pharmaceutical lines, gas systems, and sanitary food-grade fluid loops.
