Nibco H-10785W Inline Spring Check Valve 1-1/4 Inches Press End Forged Dzr Brass H-107X

Product Description

The NIBCO H-10785W is a 1-1/4 inches inline spring check valve built for residential and commercial plumbing, hydronic heating systems, and fluid control applications. Part of the Webstone PRO-CONNECT PRESS series H-107X, this valve uses a press end connection style for fast, flame-free installation. That makes it a strong choice for plumbers and mechanical contractors who need reliable, leak-tight connections without soldering. The forged DZR brass body resists dezincification, which is a common problem when brass valves are exposed to aggressive or high-chloride water. DZR brass is a preferred body material in potable water and hydronic heating systems because it maintains structural integrity over years of service. The spring-loaded check valve design allows flow in one direction and closes automatically when flow stops or reverses. This prevents backflow, water hammer, and system contamination without requiring any manual intervention. The H-10785W is rated for media including water, gas, and oil, so it works across a wide range of plumbing and HVAC applications. The 200 psi cold water pressure rating and 250 degree F temperature rating give this valve the performance headroom needed for most commercial and light industrial hydronic systems. EPDM softgoods provide a durable, flexible seal that holds up well against hot water and glycol-based fluids commonly used in radiant floor and hydronic heating loops. The trim package combines DZR brass, rubber, and stainless steel components for corrosion resistance throughout. At 5.45 inches inlet to outlet length and 2.31 inches in diameter, this valve fits neatly into tight mechanical spaces. Low lead compliance makes it suitable for potable water installations where regulatory requirements apply. This is an import product.

• Press end connection eliminates soldering for faster, cleaner installation in tight spaces
• Forged DZR brass body resists dezincification for long service life in potable water and hydronic systems
• EPDM seals rated to 250 degrees F handle hot water and glycol-based heating fluids
