| 20110240893 | Valve Actuator Having Synchronous Motor Having Plastic Bushings - A synchronous motor and a valve having a valve actuator and valve assembly is provided. The valve actuator includes the synchronous motor. The synchronous motor utilizes a magnetic coil, a stator and a rotor to generate rotational movement to drive the valve member for the valve assembly. The valve has a normal state in which the valve is maintained when power is not supplied to the motor. The valve has a non-normal actuated state when power is supplied to the motor. The motor is stalled in the non-normal state to maintain the valve in that state. The rotor includes a rotor shaft that passes through a magnetic hub of the stator. The rotor shaft is supported by a plurality of plastic and/or nylon bearings to prevent corrosion therebetween when the rotor shaft and bearings remain in a substantially fixed orientation for an extended period of time. | 10-06-2011 |
| 20110140015 | Valve Actuator with Lock Mechanism - A valve actuator with manual lock is provided. The valve actuator with manual lock includes a locking button arrangement that is operably coupled to a shaft extending along an axis of rotation of a drive train. The locking button arrangement is selectively engageable with a housing of the valve actuator to lock the drive train in a selected orientation. | 06-16-2011 |
