Abstract
An isolation valve system includes a main body (), an actuator body () and a sealing membrane () arranged at a high pressure portion () of the isolation valve system. The sealing membrane mechanically attaches the actuator body to the main body. The sealing membrane further seals the high pressure portion from a low pressure portion (). A burst plug () is arranged against the main body and supports the actuator body. An activation arrangement () is arranged for allowing an at least partial displacement of the burst plug, typically causing a phase transition. The sealing membrane is dimensioned to break when the actuator body is moved due to the displacement of the burst plug. The isolation valve system includes preferably a stack () of substrates (-) being bonded together. The substrates have micromechanical structures, which form at least the actuator body and the sealing membrane.
