A safety valve is for controlling dispensing of a fluid flow from a conduit. A valve body forms an inlet opening of the fluid, an outlet opening of the fluid, and a main passageway for the fluid which fluidly connects the inlet opening to the outlet opening. At least one fluid relief opening fluidly communicates with the outlet opening through a valve seat. A shutter elastically cooperates with the valve seat to be biased by an elastic device to sealingly close the valve seat, and to open said seat when the pressure of the fluid in the outlet opening exceeds the force applied by said elastic device.

Apparatuses regulate the flow of fluids, such as, for example, water or other like fluids, through pipes. The apparatuses comprise a poppet valve having a spheroid-shaped valve portion and one or more shims for adjusting effective spring length during use thereof. Specifically and without being bound by theory, the apparatuses of the present invention creates a backward pressure in fluid traversing a pipe, wherein the backward pressure within the pipe provides compression to the fluid effectively compressing entrapped gas bubbles within the fluid, allowing more accurate water meter measurements. Moreover, the apparatuses of the present invention provide backflow prevention. Systems and methods for regulating the flow of fluids within a pipe are further provided.

A check valve for a fluid distribution system can include a valve body defining a valve bore defining a cylindrical shape, the valve body comprising an annular body and a fixed cross member secured to the valve body and extending across the valve bore, a position block secured to the cross member of the valve body, extending from the cross member, and defining a pivot bore; a pivot pin positioned within the valve body and extending through the pivot bore of the position block, the pivot pin positioned entirely within the cylindrical shape of the valve bore; and a valve member positioned within the valve body and configured to rotate about the pivot pin to a closed position when a pipe system termination fitting attached to the valve body is dislocated fr om the valve body or when the fluid moves in a negative flow direction of the check valve.

The invention relates to a water-saving device which is fully automated and comprises a complete electronic control system, the possibility of connection to the aqueduct supply network and a hydraulic generator for saving energy. The device according to the invention communicates with a modular system that optionally reduces the water flow of the shower to 50% and diverts the other 50% to the storage tank, by means of the electronic interface. The device according to the invention is applicable in the construction industry.

A backflow preventer adapted for installation in an inner conduit of a hose coupling of a hydrant is disclosed. The backflow preventer contains a non-return device having a closing body, a seal seat, and a resetting device. The resetting device is adapted to resiliently pretension the closing body into sealing engagement against the seal seat.

A wireless communication system includes a plurality of sensors and a device. Each sensor is configured to measure data and communicate over a network using low power signal communication. The device is connected to an in-wall power source and configured to wirelessly communicate over the network using low power signal communication. Further, the device is configured to transmit data from the sensors to a remote gateway using high power signal communication.

A sanitary insertion unit (1), including an insertion housing (6), in which insertion housing a valve having a valve piston (10) is provided, which valve piston is slidably guided in the insertion housing and can be moved from a resting position under the pressure of the inflowing water against the restoring force of at least one restoring element (11). The restoring unit has at least one movement damper (12, 13), which damps or brakes the movement of the valve piston from the resting position to the open position.

There is provided a system separator having a backflow preventer including a housing enclosing a main flow conduit, a valve seat inside the housing on the main flow conduit, and a valve body movable relative to the valve seat to close off the main flow conduit together with the valve seat in a closed position and to release the main flow conduit in an open position. The valve body is alternately movable between the closed position and the open position by at least one of a pressure difference in the main flow conduit or a force of a spring element, and the main flow conduit is divided in the area of the valve body into at least one outer flow conduit and one inner flow conduit, and the valve body encloses the inner flow conduit and forms at least one valve-body valve seat on the inner flow conduit.

A testing device for backflow prevention devices, the testing device comprising a first connection portion adapted for connection to one of a high pressure side or a low pressure side of a backflow prevention device, a second connection portion adapted for connection to the other of the high pressure side or the low pressure side of the backflow pressure device, and an electronic differential pressure gauge positioned in fluid communication with the first connection portion and the second connection portion and adapted to measure the differential pressure between the high pressure side and the low pressure side of the backflow prevention device.

A check valve includes a valve body defining a valve bore extending from a first axial end to a second axial end, the valve body including an annular body and a cross member secured to and extending across the valve bore from the annular body on one side of the valve body to the annular body on an opposite side of the valve body, the valve bore at the cross member divided into more than one portion by the cross member; a position block extending from the cross member; a valve member positioned within the valve body and configured to rotate between an open position and a closed position; and a pivot pin extending from the valve member, engaged with the position block, and fixed with respect to the valve member; the valve member and the pivot pin configured to rotate together between the open position and the closed position.
