Consolidated 2900 Pilot Operated Relief valves come

configured directly from the factory with specially designed

filters to ensure long term operation. These filters should be

maintained based on the service conditions and cleanliness

of the media the valve will be exposed to. Depending on

the amount of contamination expected to be introduced to

the valve, these filters need to be regularly inspected and

replaced to ensure proper flow through the valve is maintained.

Regular maintenance intervals should be established based

on inspection of the filter at the time of service. Heavy

accumulation at the filter is an indication that more frequent

maintenance is needed. In applications that call for exposure

to a significant amount of contaminants, our high capacity

filters should be installed that allow regular maintenance to

be performed easily. Please consult your factory authorized

representatives for details on how to obtain this configuration.

The high capacity filter configuration can be installed with

independent filters that allow the maintenance to be

performed while the valve remains in service.

Note: See page 74 for replacement filter parts information.
