The 316 Stainless Steel Swing Check Valve with Hard-Faced Seats is designed for reliable backflow prevention and extended service life in high-pressure and high-temperature environments. Built from ASTM A351 CF8M (316 stainless steel), it offers exceptional corrosion resistance and structural integrity, making it ideal for use in chemical, marine, oil, and process industries.
Featuring hard-faced (HF) seating surfaces, this valve ensures superior wear resistance and long-term sealing performance even under harsh operating conditions. The bolted bonnet design allows for easy maintenance, while the graphite gasket provides excellent sealing capability at elevated temperatures.
Complying with ANSI B16.5 Class 150 flange standards and ANSI B16.10 face-to-face dimensions, this valve delivers precise alignment, leak-free connections, and compatibility with standard pipeline systems.
A flanged swing check valve allows fluid to flow in one direction while automatically preventing reverse flow. The swing-type disc opens fully during forward flow and closes when flow reverses, protecting pumps, pipelines, and downstream equipment from backflow and pressure surges.
Hard-faced seats provide superior wear resistance and maintain long-term sealing performance under high-pressure, high-temperature, and abrasive conditions. This ensures reliable operation over time, reducing maintenance needs in demanding industrial environments.
316 stainless steel (ASTM A351 CF8M) offers excellent corrosion resistance, high strength, and durability, making it ideal for chemical, marine, oil, and process industry applications. Its resistance to pitting and chemical attack ensures long-term reliability even in harsh environments.
ANSI B16.5 Class 150 flanges ensure precise alignment, leak-free connections, and compatibility with standard pipeline systems. ANSI B16.10 face-to-face dimensions guarantee consistent installation lengths for reliable integration with existing piping layouts.
Graphite gaskets provide excellent sealing performance at elevated temperatures, while the swing disc and hard-faced seats ensure smooth operation and tight closure. Together, these features deliver reliable, maintenance-free performance in high-pressure and high-temperature conditions.
