摘要： A liquid control valve (320) that is utilized in a liquid treatment system includes a valve body (322). The valve body includes a plurality of liquid ports (A, B, C D, E, F) and a plurality of annular flow cavities. A piston (328) which includes at least one annular flow passage and a longitudinal flow passage, is selectively movable within a bore (324) within the valve body responsive to operation of at least one motor. The piston is selectively axially positionable within the bore to enable liquid flow through a plurality of flow paths. The exemplary valve enables treatment material housed in an associated liquid treatment tank to undergo a regeneration cycle as a result of liquid flow though the valve, while the valve outlet port that is operable in a valve service condition to deliver treated liquid, is continuously not in fluid flow connection with any other port the valve during the regeneration cycle.

摘要： A water delivery control system operates to selectively deliver water from a water source to water use devices. The system includes at least one controller that wirelessly communicates messages with a portable user device. The system includes a water control valve and a motor that is operative to selectively move at least one valve element of the valve. A water meter is operative to measure water flow that corresponds to flow through the valve. The controller is operable to cause the valve to enable or prevent flow through the valve responsive at least in part to water flow data. The controller is operative to determine a water use condition responsive to a water usage pattern, and to cause at least one message to be sent to the portable user device responsive to the determined water use condition.

摘要： A control valve (10) includes a valve body with a plurality of ports (A, B, C, D, E, F) and a plurality of annular flow passages (53, 55,57). A piston (34) which includes a plurality of annular flow passages and a longitudinal flow passage is selectively movable within a bore (32) within the valve body through operation of a valve controller (70). The valve controller is selectively operative to control the position of the piston so as to enable liquid flow through a plurality of flow paths. A pump controller is operative to selectively control operation of a water well pump that supplies water to the control valve.

摘要： An exemplary valve control system includes a master controller that wirelessly communicates with a plurality of slave controllers. The slave controllers are each associated with respective devices and sensors. In exemplary arrangements a valve slave controller is associated with a motor that controls a condition of a valve. An exemplary control valve includes a valve body with a plurality of ports (A, B, C, D, E, F) and a plurality of annular flow passages. A piston is selectively movable within a bore within the valve body through operation of the motor and valve slave controller. The valve slave controller is selectively operative to control the position of the piston so as to selectively enable liquid flow through the valve.

摘要： An apparatus for detecting salt level within a water treatment system is provided and includes a biasing member, a paddle operatively connected to the biasing member, and an actuator operatively connected to the biasing member. The biasing member biases the paddle in a first position when the salt level is below the bottom of the paddle. The paddle is configured such that when the salt level is above the bottom of the paddle sufficient force from the salt is applied to one of the sides of the paddle to overcome the biasing force of the biasing member and move the paddle to a second position. The actuator is configured to cause a signal to be outputted that indicates that the salt level needs to be replenished in response to the paddle being in the first position.
