WCB Flanged Check Valve

High-Performance Carbon Steel Backflow Prevention

The Kunjian Tech WCB Flanged Check Valve is engineered for high-pressure industrial environments where reliability and safety are non-negotiable. Built from premium ASTM A216 WCB cast steel, this automatic valve ensures one-way flow, protecting your pumps, compressors, and pipeline infrastructure from the damaging effects of backflow.

Key Performance Features

• High-strength ASTM A216 WCB body offers excellent durability for high-temperature and high-pressure service.
• Features a metal-to-metal or hard-alloy seat (Stellite) for superior wear resistance and zero-leakage performance.
• Designed to meet API 6D and ASME B16.34 standards with flanged ends (ASME B16.5) for seamless integration into global piping systems.
• The streamlined flow path minimizes turbulence and energy loss, optimizing system efficiency.
• Bolted cover design allows for easy internal inspection and field maintenance without removing the valve from the line.

Industrial Applications

Ideal for B2B sectors including petroleum refining, chemical processing, water treatment, and power generation, this valve is suitable for water, oil, and gas media across a wide temperature range (-29°C to 425°C).
