Nibco NJ7K00A Y-pattern Swing Check Valve 1 Inch Solder

Product Description

The NIBCO NJ7K00A is a Y-pattern swing check valve from the S-433-Y series, designed to allow one-directional flow and prevent backflow in plumbing and piping systems. Built with a bronze body and PTFE seat material, this valve handles up to 300 psi at a 150 lb pressure class. The solder end connection provides a secure, leak-resistant joint for copper pipe installations. With a top-to-inlet center dimension of 2.31 inches, it fits within standard commercial and industrial piping layouts. Licensed plumbers and mechanical contractors are the typical installers for this type of valve.

The NJ7K00A is suited for commercial, mechanical, and industrial piping applications where backflow prevention is required in horizontal swing configurations. The Y-pattern body orientation reduces pressure drop compared to standard inline check valves, making it a practical choice in high-flow mechanical systems. This valve is domestically manufactured and carries a 5-year limited warranty. Note that this valve is not rated for potable drinking water service per California Section 116875 requirements due to its low-lead compliance status.

Installation Notes

Installation should be performed by a licensed plumber or mechanical contractor in accordance with applicable local and IAPMO plumbing codes. Shut off the water supply and relieve system pressure completely before soldering or making any connections. The valve is designed for horizontal swing operation and should be oriented correctly per the flow arrow marked on the body. Avoid excessive heat during soldering to protect internal PTFE seat components.
