摘要： A valve assembly includes a butterfly valve rotatably moveable between a closed position and an open position, and a shaft extending from the butterfly valve and rotatable about a longitudinal axis to move the butterfly valve between the open position and the closed position. The valve assembly further includes an actuator having a body operable to maintain an end portion of the shaft, the actuator operable to cause the shaft to rotate about the longitudinal axis, a housing sized to retain a portion of the shaft, the housing operable to be in removeable contact with the body, a seal intermediate the body and the shaft, the seal having an outer sealing surface contacting the body and an inner sealing surface contacting the shaft, and an anti-rotation interface between the seal and the housing.

摘要： Presented are a single coil apparatus and a method of forming. An exemplary apparatus includes solenoid assembly. The solenoid assembly includes a core tube extending along a longitudinal axis. The solenoid assembly further includes a first magnet and a second magnet located outside the core tube, the first magnet spaced along the longitudinal axis from the second magnet, and an excitation coil disposed radially outward of the first magnet and the second magnet.

摘要： Presented are a method, apparatus and valve assembly for preventing rotation. An exemplary valve assembly includes a butterfly valve rotatably moveable between a closed position and an open position, and a shaft extending from the butterfly valve and rotatable about a longitudinal axis to move the butterfly valve between the open position and the closed position. The valve assembly further includes an actuator having a body operable to maintain an end portion of the shaft, the actuator operable to cause the shaft to rotate about the longitudinal axis, a housing sized to retain a portion of the shaft, the housing operable to be in removeable contact with the body, a seal intermediate the body and the shaft, the seal having an outer sealing surface contacting the body and an inner sealing surface contacting the shaft, and an anti-rotation interface between the seal and the housing.
