Zusammenfassung:	A valve actuator (202) is provided that comprises a unitary housing (204) and a piston (206) translatably mounted within the housing (204). The piston (206) comprises a first portion (208) having a first diameter and a second portion (210) having a second diameter that is greater than the first diameter. A position sensor (216) having a third diameter at least as large as the second diameter is fixedly coupled to the housing (204) and to the piston (206) for determining the position of the piston (206).
