Description
Davis 1563 8" Wafer Check Valve CF8M 150LB 316SS Disc Inconel Spring As-Is
The Davis 1563 is an 8-inch dual-plate wafer check valve with a CF8M cast stainless steel body rated to ANSI Class 150. It features a 316SS disc and Inconel X-750 torsion springs — materials chosen for corrosion resistance in demanding fluid handling applications. This unit is being sold as-is: each of the two springs has one arm broken. The springs are a standard replaceable component, making this valve well suited for repair or as a parts source.

Applications
Wafer check valves like the Davis 1563 are used in industrial piping systems to allow flow in one direction and automatically prevent backflow when flow stops or reverses. The wafer style mounts between two standard ANSI flanges with through-bolts, making it compact and easy to install in tight spaces compared to flanged or threaded check valves. CF8M bodies and 316SS internals are standard in chemical processing, water treatment, oil and gas, and marine piping where corrosion resistance is required. Inconel X-750 springs are specified for high-temperature or corrosive service where standard stainless springs would degrade. An 8-inch Class 150 valve of this construction is typical in process plant headers, pump discharge lines, and cooling water circuits. Because the springs are replaceable, a valve with broken spring arms like this one can often be returned to full service at low cost with replacement springs sourced from the manufacturer or an aftermarket supplier.
This Davis 1563 8" Wafer Check Valve is being sold as-is due to broken springs — each of the two Inconel X-750 springs has one arm broken. The springs are a replaceable component, so this valve is a good candidate for repair or use as a parts source. The CF8M stainless body and 316SS disc appear structurally sound with no visible cracking or heavy corrosion; the body shows general surface wear consistent with prior industrial service. Bolt/lug holes are intact. Please review all photos carefully and contact us with any questions before purchasing.
