When the valve is utilized within environments involving gas or low viscosity liquid media, the AOC-3111 type self-operated pressure regulating valve is optimally positioned upright on a horizontal pipeline. In instances where space constraints dictate otherwise, it may be installed in an inverted or diagonal orientation. Notably, if the medium is verified as clean, the installation of part 3 is rendered unnecessary, streamlining the setup process.
In scenarios where the valve is applied to steam or high viscosity liquid media, the AOC-3111 type self-operated pressure regulating valve is customarily mounted in an inverted position on a horizontal pipeline. This method ensures seamless functionality and optimal performance of the system.
