Ntchito yaelectro-hydraulic servo valavu ya SM4-20 (15) 57-80 / 40-10-h607hndikusintha zizindikiro zamagetsi ndikuyika zizindikiro za hydraulic kudzera mu valve, kanikizani mphamvu yothamanga, ndikusintha kuti liwiro kapena dongosolo limafika pamtengo wopatsirana.

Mu servo, ochita hydraulic, poyerekeza ndi ochita zamagetsi komanso a mapangidwe am'madzi, ali ndi mawonekedwe a liwiro labwino, mphamvu yokhazikika, komanso luso lamphamvu logwiritsa ntchito. Kumbali inayi, zinthu zamagetsi nthawi zambiri zimagwiritsidwa ntchito potumiza zizindikiro ndi kukonza m'machitidwe a servo. Chifukwa chake, machitidwe amakono amakono amagwiritsanso ntchito njira zamagetsi zamagetsi, ndipo mavalo a servo ndi zigawo zingapo zotere.

AServo valavu ntchito ya servo valavu SM4- 15) 57-80 / 40-10-H607hAli ndi mawonekedwe ovuta, mtengo wokwera, komanso zofunikira kwa mafuta ndi ukhondo. Mu Hydraulic Servations, pafupifupi 70% ya zolephera za servo valve zimayambitsidwa ndi kuipitsidwa ndi mafuta, kotero ndikofunikira kulabadira zinthu zomwe zikugwira ntchito ya servo, chifukwa zimakhudza kukhazikika kwa dongosolo lonse la servo.

Mu Deh System of Steam Turbine, pali mitundu yambiri ya Servo valavu yomwe ilipo. Lumikizanani ndi Yomwek ngati mukufuna mtundu uliwonse wa Steam Turbine Philve.
