Nibco H-10787W Inline Spring Check Valve 2 Inches Press End Forged Dzr Brass H-107X

Product Description

The NIBCO H-10787W is a 2-inch inline spring check valve built for demanding residential and commercial plumbing, hydronic heating, and mechanical systems. Part of the Webstone PRO-CONNECT PRESS series, this valve is designed to allow flow in one direction and prevent backflow automatically using an internal spring-loaded disc mechanism. That makes it a reliable choice for plumbers and pipefitters who need consistent backflow prevention without manual operation or extra components. The press end connection style makes installation faster and cleaner compared to threaded or soldered fittings, reducing labor time on the job site. Compatible with press-fit tools commonly used in commercial construction and retrofit work, the H-10787W fits into existing press-connect systems with ease. The body is constructed from forged DZR brass, which stands for dezincification-resistant brass. This material resists the corrosion that can occur when standard brass is exposed to aggressive water conditions, making it a long-lasting option in a wide range of water quality environments. The softgoods are made from EPDM, a synthetic rubber known for its resistance to heat, water, and glycol-based fluids. Trim materials include a combination of DZR brass, rubber, and stainless steel for durability throughout the valve internals. This valve is rated for media including water, oil, and gas, and carries a pressure rating of 200 psi cold working pressure. The temperature rating reaches 250 degrees Fahrenheit, making it suitable for hot water heating applications. The nominal size is 2 inches, with an overall diameter of 3.15 inches and an inlet-to-outlet length of 7.28 inches. It meets low-lead compliance standards, supporting use in potable water systems where lead content restrictions apply. All Webstone products carry a limited lifetime warranty.
