Adjustable valve actuator
A valve actuator may include a valve control shaft extending at least partially through a housing of the valve actuator, wherein the valve control shaft is configured for controlling a valve position of a diverter valve. A first cam wheel may be included, where the first am wheel at least partially surrounds the valve control shaft. A first cam may be fixed to the first cam wheel, and a first microswitch may have an actuator located in a rotational path of the first cam. The valve actuator may also include a second cam wheel at least partially surrounding the valve control shaft, where a second cam is fixed to the second cam wheel, and where a second microswitch has an actuator located in a rotational path of the second cam.
1. A valve actuator, comprising:
a valve control shaft extending at least partially through a housing of the valve actuator, wherein the valve control shaft is configured for controlling a valve position of a diverter valve;
a first cam wheel extending at least partially around the valve control shaft; and
a first cam fixed to the first cam wheel,
wherein in an operational position, the first cam wheel is fixed relative to the valve control shaft, and
wherein in an adjustment position, the first cam wheel is retracted from the operational position and is rotatable relative to the valve control shaft such that the first cam is movable between non-discrete cam positions.
2. The valve actuator of claim 1 , further comprising a second cam wheel extending at least partially around the valve control shaft; and
a second cam fixed to the second cam wheel,
wherein in an operational position, the second cam wheel is fixed relative to the valve control shaft, and
wherein in an adjustment position, the second cam wheel is retracted from the operational position and is rotatable relative to the valve control shaft such that the second cam wheel is movable between non-discrete cam positions.
3. The valve actuator of claim 2 , where—in the operational position—the first cam wheel is spaced apart from the second cam wheel, such that when placed into the adjustment position, the first cam wheel and the second cam wheel each are adjustable independent of one another.
