Bronze and aluminium bronze valves offer a high level of corrosion resistance to mediums such as water and salt water. These characteristics make bronze and aluminium a suitable for many applications within the Marine environment. Air Torque Pneumatic Actuator provides a solution by offering modularity, spring-loaded design that offers fail-safe operation in harsh environments. This allows end users to achieve fast cycle times without sacrificing safety or reliability. Lug-style valves have threaded inserts at both sides of the body that allow them to be installed with only bolts and no nuts. The valve is placed between two flanges, one on each side. This setup permits either piece of piping disconnected without affecting the complete process.
