Greetings to all -
I am working on a project with several 1940 era Grinnell F-300 DPV's - 4 inch. One of the many issues with these systems is the incorrect air settings from the supplied air system and lack of proper air maintenance devices. Does anyone have a table or air pressure / trip point information on these valves? The systems are holding back a fire pump which develops 180 PSI at churn and maintains 125 PSI via the jockey pump. Currently they are providing up to 80 PSI of air in the systems .. Did I mention there were some problems with this project ? Dave P.
