Zusammenfassung:	A dynamically balanced pneumatic relay amplifier and a current-to-pneumatic converter are disclosed. The relay has a balance plug, a supply plug positioned on top of the balance plug, a bead chain connecting the balance plug and the supply plug, and a vent plug positioned on top of the supply plug. The relay also includes a baffle positioned on top of the vent plug. The converter, used in an electro-pneumatic positioner, comprises a flat strip made of magnetic material located in proximity to a nozzle, and a flow regulator having a flat spring securing a plug in a seat within the regulator. The converter also includes a cantilevered flexure integrally secured to a molded spring support, a first bias spring positioned on a first side of the flexure, and a second bias spring positioned on a second side of the flexure. The thickness of the flexure is locally reduced in an area not integrated into the molded spring support.
