In the critical world of fluid control, failure is not an option. That is why leading industries are turning to Compacted Graphite Iron (CGI), also known as Vermicular Graphite Iron, for their most demanding valve applications. Engineered to withstand extreme pressures, thermal cycling, and mechanical stress, our CGI valve castings offer a superior alternative to traditional grey or ductile iron.
Unmatched Performance for Critical Applications
Superior Strength-to-Weight Ratio CGI boasts a tensile strength nearly twice that of conventional grey iron, allowing for thinner wall designs without sacrificing integrity. This results in lighter, more compact valves that are easier to install and maintain, while still handling high-pressure differentials with ease.
Exceptional Thermal Stability Valves often operate under severe thermal loads. The unique vermicular graphite structure of CGI provides excellent thermal conductivity and low thermal expansion. This minimizes the risk of cracking and leakage during rapid heating and cooling cycles, making it ideal for exhaust systems, steam applications, and high-temperature process control.
Fatigue Resistance In dynamic environments where pressure fluctuates constantly, fatigue resistance is crucial. CGI’s microstructure effectively blocks crack propagation, ensuring your valves maintain their sealing performance and structural integrity over a longer service life compared to standard cast iron.
