In cast valve configurations, three-piece designs are available with either flanged or threaded ends, offering versatile connection options for different piping systems. Two-piece designs also support both flanged and threaded connections, making them suitable for a wide range of installation requirements. For larger valves or those requiring higher torque, gear-operated mechanisms ensure smoother and more precise operation. These configurations provide reliable solutions that balance durability, performance, and ease of maintenance in demanding industrial environments.
