Use of antifriction coating for improving the efficiency of miniature electromagnetic proportional valves. Part 2. Experimental research

Abstract

This article presents an experimental statistical analysis of the output characteristics of the Russian prototype of a proportional gas valve with an anti-friction coating of molybdenum disulfide applied to the armature surface. Regression models have been built that describe the stages of valve opening and closing (increase and decrease in duty cycle, respectively). Conclusions about the effectiveness of the use of AFС in a proportional valve are formulated.
