This paper describes a procedure for determining performance degradation of mobile hydraulic proportional valves when subjected to various particle size ranges and concentration levels of AC Fine and Coarse Test Dust. The procedure was applied to both poppet and sliding spool type valves used as both pilot and main stages.
