Value Collection 101-503NL Brass Swing Check Valve 1/2 in

Product Description

The VALUE COLLECTION 101-503NL is a brass swing check valve designed to allow one-directional flow and prevent backflow in copper piping systems. Built with a brass body and brass seal, this valve is rated at 200 WOG (water, oil, gas) and connects via C x C (copper sweat) end connections. It is suited for plumbing and light mechanical systems where backflow prevention is required. The swing-type disc design opens under forward pressure and closes by gravity and reverse flow, making it a reliable passive component for residential and commercial water lines. Plumbers and pipefitters are the primary installers of this fitting.

This valve is intended for use in copper pipe systems at 1/2 inch pipe size. Typical applications include domestic water supply lines, hydronic heating circuits, and general plumbing installations where flow directionality must be controlled. The 200 WOG pressure rating makes it appropriate for standard service pressures found in residential and light commercial plumbing systems. It is packaged as a single unit and is suitable for direct replacement or new installation work.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the applicable International Plumbing Code (IPC) requirements. Shut off the water supply and fully depressurize and drain the line before cutting into existing pipe. Use proper flux and lead-free solder for all sweat connections, and observe local code requirements regarding solder composition for potable water systems. Verify flow direction marked on the valve body before soldering to ensure correct orientation.
