⭐ Key Features and Benefits
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.
High-Pressure Integrity: The 1000WOG rating and robust SS316 construction ensure the valve maintains integrity and safety in high-pressure service environments.
Superior Material Quality: Precision cast SS316 (CF8M) body and cap provide exceptional resistance to general and chloride-induced corrosion, maximizing service life.
Wide Service Temperature: Rated from -20°C up to +232°C, making it highly versatile for both hot and cold utility and process lines.
Easy Maintenance: The threaded connection and simple design allow for relatively easy in-line access and replacement compared to welded or flanged alternatives.
