⭐ Key Features and Benefits

 

  1. Reliable Backflow Prevention: The Swing Check Mechanism uses a hinged disc that opens under forward flow and closes automatically under gravity or back pressure, effectively preventing media from returning to the pump or source.

  2. High-Pressure Integrity: The 1000WOG rating and robust SS316 construction ensure the valve maintains integrity and safety in high-pressure service environments.

  3. Superior Material Quality: Precision cast SS316 (CF8M) body and cap provide exceptional resistance to general and chloride-induced corrosion, maximizing service life.

  4. Wide Service Temperature: Rated from -20°C up to +232°C, making it highly versatile for both hot and cold utility and process lines.

  5. Easy Maintenance: The threaded connection and simple design allow for relatively easy in-line access and replacement compared to welded or flanged alternatives.

🏭 Ideal Applications

 

  • Chemical and Petrochemical Processing

  • General Utility Lines (Water, Steam, Compressed Air)

  • Oil and Gas Pipelines

  • Pump Discharge Lines where reliable sealing and corrosion resistance are essential.
