Vali ya mpira wa umeme (valvu inayodhibiti PID) ina sifa za kutegemewa sana na maisha marefu ya huduma. Vali hutumia pete ya grafiti ya PTFE na pete ya muhuri ya shina ya EPDM mbili ili kuongeza ufungaji wa vali, huandaa blade ya kurekebisha ya mtu mmoja ili kurekebisha tofauti ya shinikizo la nyuma. Kazi zake ni pamoja na mtiririko wa asilimia sawa, nguvu ya juu ya kuzima 1.4Mpa, shinikizo la kufanya kazi lililokadiriwa PN16, tofauti ya juu ya shinikizo la kufanya kazi 0.35Mpa, kitufe cha mzunguko mfupi wa kiendeshaji cha mwongozo, na halijoto ya kufanya kazi ya -5°C hadi 121°C. Vali inatumika kwa maji, mvuke au glikoli ya maji 50%.
