1. Integrally Forged Valve Body Advantage: The forged valve body can withstand higher design pressures and pressure fluctuations (pressure pulsations). This allows you to offer customers lug check valves rated for Class 600, 900, or even higher pressure classes.



2.Ultra-High Pressure Resistance & Excellent Impact Resistance Advantage: The superior toughness of forged materials enables effective resistance to fatigue stress caused by water hammer impact, system vibration, and frequent start-stop cycles.



3.Wide Temperature Range Compatibility Advantage: The dense material structure reduces the risk of material performance degradation and leakage in ultra-low temperature (e.g., LNG applications) or high-temperature environments.


4.Ultimate Safety Choice Advantage: It fundamentally eliminates potential failure risks caused by internal defects (such as shrinkage cavities, sand holes) that may exist in cast components, ensuring higher safety.
