    摘要： An isolation valve system comprises a main body (32), an actuator body (34) and a sealing membrane (307). The sealing membrane (307) is arranged at a high pressure portion (36) of the isolation valve system. The sealing membrane (307) mechanically attaches the actuator body (34) to the main body (32). The sealing membrane (307) further seals the high pressure portion (36) from a low pressure portion (38). A burst plug (315) is arranged against the main body (32) and supports the actuator body (34). An activation arrangement (50) is arranged for allowing an at least partial displacement of the burst plug (315), typically causing a phase transition. The sealing membrane (307) is dimensioned to break when the actuator body (34) is moved due to the displacement of the burst plug (315). The isolation valve system comprises preferably a stack (30) of substrates (301- 304) being bonded together. The substrates (301-304) have micromechanical structures, which form at least the actuator body (34) and the sealing membrane (307).

    摘要： A single use valve (10) comprises a plate (12) having an internal filter structure (28). A sealing substance (20) covers an inlet (14) to the filter structure (28). A heater arrangement (16) is arranged at the plate (12) in the vicinity of the sealing substance (20) for converting electrical current into heat and thereby melting or evaporating the sealing substance (20) . The heater arrangement (16) conducts at least a part of the current, and preferably the entire current, along a conduction path not including the sealing substance (20) . The melting of the sealing substance (20) thereby becomes independent on the existence of a complete electrical connection through the sealing substance (20). The heater arrangement (16) has therefore preferably its main heat emission in an area surrounding the sealing substance (20). The sealing substance (20) can be of any non-porous material.
