1. A fluid regulator, comprising:
- one or more fluid inlets configured to receive a first input flow of fluid;
a valve shaft configured with at least;
a first lobe,a second lobe,a first valve shaft port, anda second valve shaft port;
an electric motor configured with a first electric circuit and a second electric circuit;
a first housing, the first housing having a connector configured to removably engage a receiving area of an output valve having a second housing, the connector providing a fluid conduit to the output valve when the connecter is seated into the receiving area of the output valve second housing;
an actuator configured to;
open the output valve to provide a fluid flow path from the output valve in response to;
receipt of a first electrical signal at an electric motor of the actuator, cause a rotation of a valve shaft of the actuator in a first rotational direction towards a first valve shaft position,in response to the first lobe of the rotating valve shaft interfacing with the first electric circuit,cause the valve shaft of the actuator to stop at the first valve shaft position,cause the electric motor to reduce or halt power consumption, andenable, while the valve shaft of the actuator is at the first position, the first input flow of fluid to flow through the first valve shaft port through the connector to the output valve second housing;
close the output valve to obstruct the fluid flow path in response to;
a subsequent electrical signal at the electric motor of the actuator which causes the valve shaft of the actuator to rotate in the first rotational direction towards a second valve shaft position which in turn causes,the second lobe of the rotating valve shaft to interface with the second electric circuit, which in turn causes, at least in part the valve shaft to stop at the second valve shaft position, which in turn causes,the electric motor to reduce or halt power consumption, andwherein while the valve shaft of the actuator is at the second valve shaft position, the second input flow of fluid is enabled to flow towards the second valve shaft port through the connector from the output valve second housing.

Abstract
Embodiments of a fluid flow regulating device and methods of using the same are described. Certain embodiments manages fluid flow between one or more input ports and output ports at least partly in response to fluid pressure changes and/or by a mechanism driven by fluid flow, optionally without using electrical power.
