铜螺纹止回阀

产品概览

The Copper Thread Check Valve is a compact, non-return valve designed for potable water systems, HVAC, and general plumbing applications. Constructed from lead-free copper alloy (C12200/C84400), this valve ensures safe and reliable flow control with minimal pressure drop. Featuring NPT or BSP threaded connections, it is ideal for residential, commercial, and light industrial systems requiring corrosion resistance and ease of installation.

主要功能

Lead-Free Copper Construction:Compliant with NSF/ANSI 61 and WRAS standards for drinking water safety.Resists corrosion and scaling in chlorinated water environments.

Threaded Connections:NPT (National Pipe Thread) or BSP (British Standard Pipe) threads for tool-free installation.Compact design saves space in confined installations.

Low Resistance Flow Path:Optimized internal geometry reduces pressure drop (Cv ≥ 1.0 for DN25).Spring-assisted disc ensures rapid closure to prevent water hammer.

Durable Sealing:EPDM or NBR seals for zero leakage (Leakage Class VI per ISO 5208).Suitable for temperatures up to 120°C (248°F).

遵守规定：Meets ASME B16.34, ISO 228, and EN 1254 standards.

运行优势

Safe for Drinking Water: Lead-free copper ensures compliance with global water safety regulations.

Easy Installation: Threaded connections eliminate welding, reducing labor time and costs.

Corrosion Resistance: Ideal for chlorinated water and humid environments.

Low Maintenance: Self-cleaning design and replaceable seals extend service life.
