Our Lead-Free Brass Check Valve is engineered to deliver uncompromising safety, durability, and reliable one-way fluid control for diverse industrial, commercial, and residential applications. Crafted from premium CW511L lead-free brass alloy, this valve strictly complies with global health and safety standards, ensuring zero lead contamination in potable water systems and safeguarding public health. The CW511L alloy features low-lead design and arsenic enhancement, effectively solving dezincification corrosion issues while maintaining excellent machinability.

Designed for optimal performance, the valve features a spring-loaded mechanism for fast, bubble-tight closure, minimizing pressure drop and preventing backflow to protect pumps, pipelines, and system components. Its corrosion-resistant body withstands temperature ranges from -20°F to 400°F and maximum working pressure up to 400 PSIG, maintaining stability in harsh environments such as process water systems, HVAC networks, irrigation setups, and marine applications . The precision-engineered structure ensures long service life with minimal maintenance, making it a cost-effective solution for long-term installations.

As a professional manufacturer with 30+ years of experience, we specialize in **OEM/ODM custom solutions** to tailor the valve to your unique requirements. Our one-stop customization service covers every detail: material customization (naval brass for marine use, DZR brass for aggressive water conditions, and CW511L as the standard lead-free option), size range from 1/2" to 2" with flexible end connections (NPT threaded, solder, male/female), and surface finishes (chrome-plated, brushed nickel, orb). We support personalized structural designs via 3D and CAD drawing, including integrated strainers, gravity-type closures, and compact models for space-constrained installations.

Our OEM/ODM capabilities extend to branding support-we can engrave your logo and customize packaging to meet your market demands. With a low MOQ of 500 units, free samples, and 5-year warranty, we ensure flexible production and product reliability. Every custom valve undergoes 100% factory testing for pressure tightness and performance, guaranteeing consistent quality for your applications.

Ideal for plumbing contractors, equipment manufacturers, and distributors, this lead-free check valve balances safety, performance, and customization.
