Abstract: A module for detecting the angular position of the drive shaft of a valve includes a printed circuit proximate a drive shaft of a valve body, or of an extension element thereof or a motor shaft of a valve actuator. The module also includes a magnet(s) fastened to the drive shaft, a magnetic sensor(s) supported on the printed circuit, and a communication interface. The magnetic sensor(s) generate an electrical signal indicating the position of the magnet(s). The communication interface remotely transmits a corresponding reading. The acquisition of the reading can be carried out at pre-set time intervals, which can be managed according to the requirements of the production process. The detection module is free of wired connections with the outside. A valve and an adapter element are also provided with the module, and a method for detecting the open state of the valve remotely by the module.

Abstract: Systems and methods are provided for automatically actuating preexisting water shut-off valves. A coupling of a valve actuator is connected to a handle of the valve, such that a motor of the valve actuator causes the selective opening and closing of the water shut-off valve. A controller monitors and controls valve actuation by controlling the motor. In addition to actuating the water shut-off valve upon detection of leak conditions, the controller may actuate the valve in order to test the water supply system or to test operation of the water shut-off valve. The operating status of the water shut-off valve may thus be monitored in order to detect or address problems with the water shut-off valve to prevent unexpected valve failure after a leak is detected.

Abstract: A valve automation mechanism that can be easily attached to a large manual valve, can motorize the valve, and is sufficiently downsized so as to be placeable in a narrow installation space is provided. A valve automation mechanism includes a gear attaching mechanism, a support mechanism, a drive mechanism, and a control part. Further, the gear attaching mechanism has a handle rotating gear. Further, the drive mechanism rotates the handle rotating gear and generates a driving force for motorizing the rotation of a handle.

Abstract: 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.

Abstract: A flow rate adjusting valve, in which a needle valve is arranged so as to face a fluid passage of a main body, is equipped with a handle configured to enable a rotational operation to be performed manually, an electric motor configured to be operated remotely, and a motive power transmission mechanism that selectively switches between a rotational operating force of the handle and a driving force of the electric motor, and to transmit the force to the needle valve. The switching is performed by causing the handle to be moved in a direction of an axis of rotation.

Abstract: 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.
