Regular maintenance involves checking for air leaks, inspecting & cleaning the regulator components and ensuring proper lubrication if required. Troubleshooting includes addressing pressure inconsistencies, excessive vibration or irregular operation.
A relieving air regulator releases excess pressure downstream when the set pressure is exceeded. It includes a relief valve or vents to relieve the excess pressure. On the other hand, a non-relieving air regulator does not release excess pressure and maintains a closed system when the set pressure is exceeded.
To ensure accurate pressure readings, install the pressure gauge or pressure sensor at a location downstream of the air regulator. Placing it before any restrictions, filters or other components can provide a more accurate reading of the regulated pressure.
A single-stage air regulator operates with a single pressure reduction stage, directly reducing the inlet pressure to the desired set pressure. In contrast, a two-stage air regulator has two pressure reduction stages. The first stage reduces the pressure to an intermediate level and the second stage further reduces it to the final desired set pressure. Two-stage regulators are used when precise control and regulation of the downstream pressure are required.
