An actuator assembly for moving a valve between an open position and a closed position includes an actuator housing forming at least a portion of a chamber. The actuator assembly also includes a support plate arranged within the actuator housing. The actuator assembly further includes a diaphragm coupled to the actuator housing and the support plate, the diaphragm expanding and contracting in response to a working fluid within the chamber. The actuator assembly also includes an indicator rod extending through the chamber and out of the actuator housing, the indicator rod being removably coupled to the support plate, wherein the indicator rod is arranged within an opening formed in the support plate, the indicator rod secured to the support plate via a coupling mechanism that releases the indicator rod in response to a pressure from the working fluid between the diaphragm and the support plate.

Disclosed is an armature for receiving a sensor for measuring a medium in a container. The armature includes a hollow cylindrical housing designed to connect the armature to the container at least sectionally in the container. The housing includes first and second openings through which medium flows in or out; a service chamber formed in the interior of the housing between the first and second openings; a rotationally movable closing element in the housing, which, in a first position, opens the first and second openings to the medium and, in a second position, blocks a flow through the first and second openings; a sensor holder; and the sensor arranged on or in the sensor holder. The sensor holder is designed such that the sensitive element is arranged in the service chamber in the measuring/service position.

A valve assembly including a valve housing and a handle that is movable about an actuation axis to actuate a valve actuator within the valve housing between an open position and a closed position. The handle has a first opening and the valve housing has a second opening. When the valve actuator is in the closed position the first opening aligns with the second opening to enable receipt of a lockout member that prevents movement of the valve actuator from the closed position to the open position.

Hydraulic bi-directional flow switches are disclosed. A disclosed example apparatus includes a piston disposed in a fluid channel between a first fluid connection and a second fluid connection, where the first and second fluid connections define a fluid pathway for hydraulic steering fluid. The example apparatus also includes a detector to detect a movement of the piston away from a default position of the piston, where the piston is to displace from the default position when the hydraulic steering fluid flows along the fluid pathway.

A watertight electrical compartment for use in an irrigation device can include a compartment body having a chamber and a sealing section configured to mate with one or more sealing rings. A sealing cap can mate with the sealing section and/or the sealing rings to seal the chamber. A cap retainer can be advanced over at least a portion of the sealing cap. One of the compartment body and cap retainer can have internal threads to be screwed onto external threads of the other one of the compartment body and cap retainer. The cap retainer can also have a stopping feature to keep the sealing cap in its sealed position. The watertight electrical compartment can be used in a wireless flow sensor assembly, a battery operated irrigation controller, and/or a battery-operated central controller device, to provide irrigation control, and/or sensor information, without the need for AC power.

A faucet is provided, and the faucet includes a faucet body, an electrically controllable valve, a contact sensing unit, a motion sensing unit, and a control unit. The control unit determines an operation mode of the faucet based on a signal of the contact sensing unit and a signal of the motion sensing unit, and controls an on-off state of the electrically controllable valve.

The invention relates to an intelligent safety valve comprising a valve body having a first valve inlet, a valve outlet and a first sensor compartment, the first sensor compartment including a first sensor assembly, the first sensor compartment being arranged in the valve body, a first closing unit suitable for closing the intelligent safety valve, an actuator mechanically connected to the first closing unit in order to close the first closing unit, and a control unit which is connected to the actuator and is suitable for controlling the actuator, wherein the control unit is connected to the first sensor assembly in order to evaluate sets of measured values from the first sensor assembly, and wherein the first sensor assembly comprises at least one analysis sensor, for example a pH sensor, a conductivity sensor or an oxygen sensor.

A valve assembly is provided, the valve assembly includes a shaft, the shaft comprising a sight through-hole; and a flow through-hole. The valve assembly further comprises a shaft position mechanism, the shaft position mechanism comprising a driving means configured to provide movement to the shaft, and at least one diode and at least one corresponding sensor. The valve assembly further includes at least one flow path from at least one fluid inlet to at least one fluid outlet, wherein the shaft is configured to move across the at least one flow path so as to allow flow therethrough in a first position, and to block the at least one flow path in a second position.

A valve without position indicating switches. Positions of the valve are detected from current magnitude measurements and current profile analytics. The current profile may be learned initially and relearned and adapted at each operation. The valve may be opened and closed by a driver that is actuated by an electrical current to control the opening and closing of the valve. The current may be regulated by a controller to open and close the valve appropriately.
