Abstract

A valve for a water system including a water supply conduit, the valve having a valve housing that defines a valve inlet and valve outlet. The valve inlet is connected to the water conduit and at least one piston is disposed within the valve housing and is configured to direct flow within the valve. A motor associated with the valve housing is operably attached to the piston and is further configured for driving the piston between a service position, a bypass position, and a shutoff position. The valve further includes at least one sensor associated with the valve inlet or valve outlet for monitoring a water condition. A control system receives data from the at least one sensor and is configured for actuating the motor between the service position, the bypass position, and the shutoff position in response to the data.

Claims (25)

1. A bypass valve for a water system including a water supply conduit and a system control valve, said bypass valve comprising: a bypass valve housing separate from the system control valve and defining a bypass valve inlet and a bypass valve outlet, said bypass valve inlet connected to the water conduit upstream from the system control valve; at least one piston disposed within said valve housing and configured to direct flow within said valve; a motor associated with said valve housing and operably attached to said piston, said motor further configured for driving said piston exclusively between a service position, a bypass position, and a shutoff position; at least one sensor associated with one of said bypass valve inlet and said bypass valve outlet for monitoring a water condition; a control system receiving data from said at least one sensor, said control system configured for actuating said motor only between the service position, the bypass position, and the shutoff position in response to said data; and a handle being external to and attached to said valve housing through connection between said handle and said motor, and being configured so that said handle is connected to a motor clutch system which, in turn is connected to said piston for manual movement of said piston by said handle between the service position, the bypass position, and the shutoff position.

2. The valve of claim 1 , wherein said valve housing defines a softener inlet and a softener outlet,

said softener inlet opposing and aligned with said valve inlet, and said softener outlet opposing and aligned with said valve outlet;

wherein the water system includes a water treatment system; and

wherein said softener inlet and said softener outlet are configured for fluid connection with said water treatment system.

3. The valve of claim 2 , wherein said valve housing defines a bypass chamber having a bypass chamber inlet and a bypass chamber outlet;

said bypass chamber permitting flow through said valve when said piston is in the bypass position.

4. The valve of claim 3 , wherein said piston further includes:

an inlet passage associated with said valve inlet and an outlet passage associated with said valve outlet, said inlet passage and said outlet passage configured to allow flow through said piston, and

an inlet blocking portion and an outlet blocking portion, said inlet blocking portion configured to block flow from said valve inlet in the shutoff position, said softener inlet in the bypass position, and said bypass inlet in the service position, and said outlet blocking portion configured to block flow from one of said valve outlet in the shutoff position, said softener outlet in the bypass position, and said bypass outlet in the service position.

5. The valve of claim 1 , further comprising a control housing mounted to said valve housing, said control system disposed within said control housing.

6. The valve of claim 1 , wherein said at least one sensor is taken from the group including a flow meter, a pressure sensor, a temperature sensor, and a TDS sensor.

7. The valve of claim 1 , wherein said at least one sensor is a flow meter, and

said control system is configured to alert a user or actuate said piston to said shutoff position when said flow meter detects at least one of a predetermined flow rate and a predetermined flow rate for a predetermined amount of time.

8. The valve of claim 1 , wherein said at least one sensor is a temperature sensor, and

said control system is configured to alert a user or actuate said piston to said shutoff position when said temperature sensor detects a predetermined temperature.

9. The valve of claim 1 , wherein said at least one sensor is a total dissolved solids (TDS) sensor, and

said control system is configured to alert a user or actuate said piston to said shutoff position when said total dissolved solids sensor detects a predetermined dissolved solids concentration.

10. The valve of claim 1 , wherein said at least one sensor is an inlet pressure sensor associated with said valve inlet and an outlet pressure secured in said valve outlet, and

said control system is configured detect a leak in the water system using data from the inlet pressure sensor or the outlet pressure sensor,

wherein said control system alerts a user or actuates said piston when said leak is detected.

11. The valve of claim 1 , wherein said control system sends and receives signals from the Cloud.

12. The valve of claim 1 , wherein said motor has a motor housing has an aperture.

13. A bypass valve for a water system including a water supply conduit and a system control valve, said bypass valve comprising: a bypass valve housing separate from the system control valve and defining a bypass valve inlet and a bypass valve outlet, said bypass valve inlet connected to the water conduit upstream from the system control valve; a piston disposed within said bypass valve housing and configured to direct flow within said bypass valve; a motor associated with said valve housing and operably attached to said piston, said motor further configured for driving said piston exclusively between a service position, a bypass position, and a shutoff position; at least one TDS sensor associated with one of said bypass valve inlet and said bypass valve outlet for monitoring a water condition; a control system receiving data from said at least one sensor, said control system configured for actuating said motor only between the service position, the bypass position, and the shutoff position in response to said data; and a handle being external to and attached to said valve housing through connection between said handle and-said motor, and being configured so that said handle is connected to a motor clutch system, which in turn is connected to said piston to for manual movement of said piston by movement of said handle between the service position, the bypass position, and the shutoff position.

14. The valve of claim 13 , wherein said motor has a motor housing has an aperture.
