The B&K 105-603NL Stop and Waste Valve from the ProLine Series is a reliable and multi-purpose in-line valve designed for residential and commercial plumbing systems. Built from lead-free brass, this valve is engineered to regulate or stop water flow in low-pressure lines and provide a convenient method for draining the system during maintenance or seasonal shutdowns.

Its rising stem design ensures positive open and close operation, while the multi-turn six-point cast-iron handle offers a secure grip and smooth control. The valve includes a screw-on waste cap that allows flushing of the non-pressure side of the line when the valve is closed. With a pressure rating of 125 PSI WOG (Water, Oil, Gas), this valve is suitable for a variety of plumbing applications.

The solder ends are compliant with ANSI B16.18 standards, ensuring compatibility and secure installation in copper piping systems.
