Abstract

En utførelse av en ventil som er opererbar fra én posisjon til en annen posisjon ved frigjøring av et påført trykk innbefattende et hus med en boring, en ventildel anbrakt med huset, hvori ventildelen er aktuert til en posisjon i samsvar med et visst påført trykk og aktuerer mot en annen posisjon med frigjøring av det visse påførte trykk; og et avlastningssystem som frigjør trykket påført ventildelen når det påførte trykket faller under et valgt trykknivå.
