1. A High Integrity Pressure Protecting System (HIPPS) for a fluid line, the HIPPS comprising: an ON/OFF-valve includinga housing includingan inlet,an outlet,a conduit for a passage of a fluid from the inlet to the outlet,a closure element that is axially movable in a direction from the inlet to the
1. A High Integrity Pressure Protecting System (HIPPS) for a fluid line, the HIPPS comprising: an ON/OFF-valve includinga housing includingan inlet,an outlet,a conduit for a passage of a fluid from the inlet to the outlet,a closure element that is axially movable in a direction from the inlet to the outlet from an open position to a closed position,wherein the closure element opens the conduit allowing the passage in the open position and the closure element closes the conduit preventing the passage in the closed position;a hydraulic actuator includinga control element that is fixated at the closure element,a switchable hydraulic supply unit, which supplies a control face of the control element with a control pressure in an active state, and releases the control pressure from the control face in a passive state,a sensor measuring a downstream pressure of the fluid downstream from the outlet,a logic solverthat compares the downstream pressure to a critical value and switches the hydraulic supply unit to the active state allowing the closure element to move into or stay in the open position when the downstream pressure is below the critical value, andthat switches the hydraulic supply unit to the passive state allowing the closure element to stay in the closed position, when the downstream pressure exceeds the critical value, andwherein an opposite face of the control element which opposite face is arranged opposite to the control face is exposed to the downstream pressure of the fluid so that the downstream pressure of the fluid pushes the closure element into the closed position. 2. The HIPPS according to claim 1, wherein the actuator is arranged inside the housing. 3. The HIPPS according to claim 2, wherein the conduit envelops the actuator. 4. The HIPPS (1) according to claim 1, wherein the control element is a piston of the hydraulic actuator. 5. The HIPPS according to claim 1, wherein the control element is a cylinder barrel of the hydraulic actuator. 6. The HIPPS according to claim 1, further comprising a spring that pushes the closure element into the closed position. 7. The HIPPS according to claim 1, further comprising at least one sensor for identifying a position of the closure element. 8. HIPPS (1) according to claim 1, wherein the closure element includes an orifice allowing the fluid to flow from the outlet through the closure element to a back face of the control element. 9. A Method for operating an High Integrity Pressure Protecting System (HIPPS) in a fluid line, the HIPPS including an ON/OFF-valve includinga housing includingan inlet,an outlet,a conduit for a passage of a fluid from the inlet to the outlet,a closure element that is axially movable in a direction from the inlet to the outlet from an open position to a closed position,wherein the closure element opens the conduit allowing the passage in the open position and the closure element closes the conduit preventing the passage in the closed position;a hydraulic actuator including a control element that is fixated at the closure element,the method comprising the steps:supplying a control face of the control element with a control pressure, in an active state and releasing the control pressure from the control face in a passive state;measuring a downstream pressure of the fluid downstream of the outlet;comparing the downstream pressure to a critical value;switching the hydraulic actuator to the active state to hold the closure element in the open position when the downstream pressure is below the critical value;switching the hydraulic actuator to the passive state to move the closure element into the closed position, or to hold the closure element in the closed position, when the downstream pressure exceeds the critical value;exposing an opposite face of the control element, which opposite face is arranged opposite to the control face, to the downstream pressure, so that the downstream pressure of the fluid pushes the closure element into the closed position.
