Industrial AJ-1-1/2NPT-125WSP-200WOG-SpringLift Check Valve

Industrial AJ-1-1/2NPT-125WSP-200WOG-SpringLift Check Valve is a 1-1/2" NPT threaded inline backflow-prevention valve designed to stop reverse flow in piping systems. It features a forged brass body with a stainless-steel spring, a bronze poppet, and a Buna-N seating, delivering reliable sealing during forward flow and rapid closure on reverse flow under a SpringLift mechanism. The valve is rated to 200 WOG (water, oil, gas) and 125 WSP (water service pressure), making it suitable for standard industrial water lines and light process piping where backflow protection is required. Its threaded connections enable straightforward installation into existing 1-1/2" NPT pipelines without welding or flanging, offering a compact alternative to larger, flange-based check valves. This combination of robust construction and compact form factor supports use in pump discharge lines, supply branches, and other typical industrial or commercial applications where dependable one-way flow is essential.
