Kidhibiti cha Shinikizo cha Kujidhibiti kinaweza kubadilisha shinikizo na mtiririko tofauti kabla na baada ya vali ili kuweka shinikizo kabla (au baada) ya vali katika kiwango kisichobadilika, kwa kutumia nishati binafsi ya kati kudhibitiwa kama chanzo cha nguvu, bila nguvu ya nje.Inaangazia hatua inayonyumbulika, mali nzuri ya kuziba na mabadiliko ya chini ya kiwango cha kuweka shinikizo.Kidhibiti cha Shinikizo cha Kujidhibiti kinatumika sana kwa udhibiti wa kiotomatiki wa uimarishaji wa kupunguza shinikizo na uimarishaji wa kupunguza shinikizo kwa gesi, kioevu na mvuke.
Kidhibiti cha Shinikizo cha Kujidhibiti kina faida zingine kama udhibiti mzuri na sahihi, kuchukua nafasi ndogo na operesheni rahisi na Kidhibiti cha Shinikizo cha Kujidhibiti kinatumika 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.
Vidhibiti vya Kudhibiti Shinikizo vya Kujidhibiti vilivyoundwa na kutengenezwa kulingana na kiwango cha AMSE/API/BS/DIN/GB
