Abstract
A heater water valve has a servo actuator with a subfractional horsepower, low torque, high RPM motor operating on a 12 volt DC supply. A speed reducer provides rotation of an output sector gear. One travel limit position of the sector gear is provided by a resilient pad which is compressed by the sector gear to develop full motor stall torque in five degrees (5 degrees) of rotation of the sector gear, which rotates a shaft for opening and closing the heater water valve. The pad is preferably closed cell silicone foam.
