An all-in-one manifold assembly is fabricated separately from and coupled to a pressure vessel of a water filter system. The manifold assembly includes two valve assemblies configured to be rotated between an operational position, a by-pass position and a shut-off position. Rotation of the valve assemblies can occur by manual or automatic rotation. The manifold assembly may further include ports for one or more sensors. A controller can smartly operate the manifold assembly.

A valve operating machine includes a base having a housing thereon. A motor, and a planetary gearbox are mounted within cavities in the housing. A motor gear, a planetary input gear and an idler gear are mounted within a separate cavity. The motor gear is mounted for rotation with a motor shaft of the motor and the planetary input gear is mounted for rotation with a planetary gear spindle of the planetary input gear. The idler gear is engaged with the motor and planetary input gears. An output socket is connected to the planetary gearbox for connection to a key that is used to exercise a valve.

A power-assisted pipeline valve, including a valve body and a pressure relief assembly. A top of the valve body is provided with a first chute. A sliding sleeve is disposed in the valve body and has two sides respectively connected to an inner wall of the valve body through a first spring. A ball valve assembly is disposed in the sliding sleeve and connected to a valve stem. The valve stem passes through the sliding sleeve and is sleeved with a sliding shell, and the sliding shell is disposed in the first chute and provided with a rack and an electric power-assisted mechanism which is connected to the valve stem. The top of the valve body is penetrated by a first rotating shaft which is orderly sleeved with a fifth gear, a rotary table and a third spring from top to bottom. The fifth gear is meshed with the rack. The rotary table is connected to the fifth gear through a centrifugal locking mechanism. The third spring is connected to the rotary table and the valve body respectively. The pressure relief assembly is disposed on the valve body and connected to the rotary table. The present disclosure effectively solves the problems in the prior art that it is laborious for a person with a small strength to operate a manual valve, and a water hammer prevention effect is poor, which seriously affects the service life of the manual valve.

An automatic valve actuator unit and method for use with an associated manual shutoff valve configured to permit or restrict the flow of fluid through an associated supply pipe. The unit comprises a housing, an attachment mechanism for securing the housing to at least one of the associated supply pipe or manual shutoff valve, and an actuator at least partially supported in the housing and having an output shaft extending from the housing. The output shaft includes a locating member supported at a distal end thereof for non-rotatingly engaging a surface of a valve handle of the associated manual shutoff valve adjacent a point of attachment of the handle to the associated manual shutoff valve, the locating member configured to center the output shaft over an axis of rotation of the handle of the associated manual shutoff valve.

A motorized ball valve has valve body with an actuator bracket receiver. The actuator bracket receiver has a pair of rails. The ball valve also includes a valve stem extending through the actuator bracket receiver and an actuator operably connected to the valve stem. A mounting bracket is connected between the actuator and the valve body to support the actuator. The mounting bracket is captured between the pair of rails of the actuator bracket receiver to offset torsional forces generated by the actuator.

Valve systems include a valve and a valve actuator assembly for operating the valve. The valve actuator assembly includes a drive device and a hand wheel assembly that can independently be used to cause movement of the valve. An anti-back drive component is coupled to the output of the drive device, the hand wheel assembly, or both. The anti-back drive component includes a locking device and an unlocking device, each with respective protrusions that cooperate to define cavities that house pairs of springs and rollers. The shape and orientation of the cavities allows for rotation of the rollers in the cavities and the anti-back drive component by rotating the unlocking device, while preventing rotation of the rollers and the anti-back drive component via rotation of the locking device to selectively prevent rotation of the output of the drive device, hand wheel assembly, or both.

An actuator for controlling a flow regulation device. The actuator includes a drive device coupled to the flow regulation device and a motor coupled to the drive device and operable to move the drive device. The actuator further includes a processing circuit configured to receive a first measurement of a characteristic, control the actuator to reposition the flow regulation device in a first direction, receive a second measurement of the characteristic, determine an installation error associated with at least one of the actuator and the flow regulation device based on the first measurement and the second measurement.

A control system for a water filter assembly comprising a filter having an RFID tag and an RFID sensor to generate a RFID signal containing data related to the filter. A valve assembly moves between a shut off position, an operational position directing the flowpath of the water supply through the filter, and a bypass position. A controller communicate with a lawn irrigation system to determine if the irrigation system is operative. When operative, the controller has the valve assembly switch to the bypass position. The controller also receives the RFID signal to verify if the filter is proper. The controller also receives a leak signal from a leak sensor and has the valve assembly automatically switch to the shut off position if a leak occurs. The controller can name the leak sensor with a location and indicate battery life of the leak sensor.

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.
