Kidhibiti kinachojiendesha cha aina ya pistoni ambacho kinaweza kurekebisha shinikizo kama thamani iliyowekwa na nishati yake ya kati na bila nishati yoyote ya nje. Faida zaidi za kidhibiti hiki kinachojiendesha cha aina ya Piston ni kwamba kinaweza kufaa kwa mahali pa kazi bila nguvu. na hakuna vifaa vya nyumatiki vinavyopatikana, ziada, kidhibiti kinachojiendesha cha aina ya Piston kinaweza kuokoa nishati kwa mtumiaji wa mwisho, na shinikizo linaweza kubadilishwa ndani ya safu iliyowekwa.
Kidhibiti kinachojiendesha cha aina ya pistoni kina aina zifuatazo kulingana na hali tofauti za kufanya kazi:
ZZYP(aina ya kiti kimoja), ZZYM(aina ya mkono) na ZZYN(aina ya viti viwili), na kidhibiti kinachojiendesha cha aina ya PPiston pia kina vifuniko vitatu tofauti kama vile la kawaida, la shingo ndefu na aina ya kupoeza.Kwa matumizi tofauti, kidhibiti hiki cha kujiendesha cha aina ya PPiston ni kianzisha pistoni, na vali ya kudhibiti inayojiendesha yenyewe ina aina tatu tofauti za viimilisho:filamu/pistoni/mvukuto.
Kidhibiti kinachojiendesha cha aina ya pistoni kina faida zingine kama udhibiti mzuri na sahihi, kuchukua nafasi ndogo na operesheni rahisi na hutumika sana katika udhibiti wa shinikizo la gesi, mvuke au maji katika mafuta ya petroli, kemikali, nguvu za umeme, madini, chakula, nguo, mashine, sekta ya ujenzi wa kiraia.
Kidhibiti kinachojiendesha cha aina ya pistoni kimeundwa na kutengenezwa kulingana na kiwango cha AMSE/API/BS/DIN/GB
