The Cast Steel Swing Check Valve – Flanged Class 300 RF is a heavy-duty, high-performance non-return valve designed for demanding industrial service. Manufactured from ASTM A216 WCB cast steel, it provides exceptional strength, durability, and resistance to high temperatures and pressures.
This valve features a swing-type disc that allows full, unobstructed flow in one direction and automatically closes to prevent reverse flow — protecting pumps, compressors, and process equipment from potential damage. The hard-faced seats deliver enhanced wear resistance and reliable sealing, even in continuous or abrasive service conditions. The graphite gasket ensures tight, long-term sealing performance in elevated temperature applications.
With flanged ends machined to ANSI B16.5 Class 300 Raised Face (RF) standards, this valve offers secure connections and easy installation. Designed in accordance with ANSI B16.10 for face-to-face dimensions, it ensures full interchangeability with standard pipeline layouts.
A flanged swing check valve allows fluid to flow in one direction and automatically prevents reverse flow. The swing-type disc opens fully during forward flow and closes when flow reverses, protecting pumps, compressors, and pipelines from backflow and pressure surges.
Hard-faced seats provide superior wear resistance and maintain tight sealing performance even under high pressure, elevated temperatures, or abrasive service conditions. This ensures long-term, reliable operation in demanding industrial applications.
Cast steel offers excellent mechanical strength, durability, and resistance to high pressures and temperatures. It is ideal for heavy-duty industrial environments, including oil, gas, petrochemical, and process industries, where reliability and longevity are critical.
ANSI B16.5 Class 300 raised-face (RF) flanges provide secure, leak-resistant bolted connections, while ANSI B16.10 face-to-face dimensions ensure standardized installation lengths for compatibility with existing pipeline systems.
The combination of hard-faced seats and graphite gaskets ensures reliable sealing and wear resistance under elevated temperatures. The swing disc design provides smooth, low-resistance flow while preventing backflow, enabling maintenance-free operation even in continuous or abrasive service conditions.
