Abstract: A valve actuator with an instrument mounting pad and a manifold in a power module and yoke combination for mounting a valve controller instrument without tubing or mounting brackets. A cover encloses the feedback linkage between the actuator and instrument. The actuator includes a second instrument mounting pad and manifold so the power module is reversible to accommodate fail-safe opened or fail-safe closed valve conditions. A valve actuator and instrument combination is no higher than the actuator alone.
