Nibco H-10786W Pro-connect Press Inline Spring Check Valve 1-1/2 Inches H-107X

Product Description

The NIBCO H-10786W PRO-CONNECT PRESS Inline Spring Check Valve is a forged DZR brass check valve built for reliable one-directional flow control in demanding plumbing and hydronic heating applications. Rated for a 1-1/2 inch nominal pipe size, this valve features a press end connection style that allows fast, tool-free installation without soldering or threading. That makes it a practical choice for HVAC technicians, plumbers, and mechanical contractors who need to work efficiently on both new construction and retrofit projects. The H-10786W is part of the NIBCO Webstone H-107X series, a trusted line of professional-grade inline valves designed for residential and commercial plumbing systems, hydronic heating loops, radiant floor systems, and glycol-based closed-loop circuits. A spring-loaded check valve like this one prevents backflow automatically. When forward pressure exceeds the spring tension, the valve opens and allows media to pass. When flow stops or reverses, the spring closes the disc and seals the line. This protects pumps, boilers, heat exchangers, and other system components from reverse flow damage. The body is constructed from forged DZR brass, a dezincification-resistant alloy that holds up against corrosive water conditions and extended service life. Softgoods are EPDM rubber, which provides strong sealing performance across a wide temperature range. The trim combines DZR brass, rubber, and stainless steel for durability and corrosion resistance. This valve is rated to 200 psi CWP and 250 degrees Fahrenheit, making it suitable for high-temperature hydronic and steam-adjacent systems. It measures 2.51 inches in diameter and 6.59 inches from inlet to outlet. The H-10786W meets low lead compliance requirements. Media compatibility includes water, oil, and glycol mix, covering most commercial and residential hydronic system fluids.
