To ensure optimum performance in gas or low-viscosity liquid applications, the AOC-3111 Reliable Self-Operated Pressure Regulator is typically mounted in an upright position on a horizontal pipeline. This standard setup can be adjusted to an upside-down or diagonal installation only if spatial constraints exist. Should the medium be verified as clean, installation of part 3 can be omitted.
For steam or high-viscosity liquid applications, the AOC-3111 Reliable Self-Operated Pressure Regulator is expertly installed upside down on a horizontal pipeline. This configuration maximizes functionality and efficiency for more viscous media conditions.
