A fluid control device connectable to a fluid pipe includes an electric motor mechanically connected to a fluid valve configured to open and close the fluid valve. A manual motor disengagement knob is at least partially accessible to a user and mechanically connected to the fluid valve.

An integrated variable pressure and flow regulator comprising a manifold body, a pressure regulator, a flow control valve, a flow meter and a flow diverter. The manifold body includes a coupling face to which the pressure regulator is attached, a flow control valve cavity which receives the flow control valve, a flow meter cavity which receives the flow meter and a flow diverter cavity which receives the flow diverter. A central fluid transfer passageway of the manifold connects an inlet with outlet ports in fluid communication through the cavities. The pressure regulator maintains an outlet fluid pressure less than inlet fluid pressure as per a reducer pressure at outlet ports. The flow control valve maintains an outlet fluid flow rate, as per a flow rate setting, for the fluid flow at the outlet fluid pressure. The flow diverter allows to selectively divert the fluid through any of the outlet ports.

Pressure regulating systems are provided. The pressure regulating systems include a pressure sensor configured to sense pressure of water flowing through a pressure regulating device; an actuator coupled to the pressure sensor; an electronics module configured to receive pressure information related sensed pressure from the pressure sensor and process the received pressure information; and a radio module coupled to the device and configured to receive the processed sensor information from the electronics module, communicate the processed sensor information to a remote location and receive pressure adjustment information from the remote location. The received pressure adjustment information is used to adjust water pressure in the water network from the remote location.

A fluid control device includes an electric motor mechanically connected to a fluid valve and a sensor coupled to a fluid pipe section. The sensor may be a temperature, pressure or flow rate sensor. A control device processor is configured to enter into a pre-occupancy mode when powered and never previously wirelessly connected to a remotely disposed fluid monitoring and control system. The pre-occupancy mode may close the fluid valve if at least one of the following occurs: exceeding a first preset threshold for a pressure decay test; exceeding a second preset threshold for a maximum flow rate; exceeding a third preset threshold for a maximum flow duration; exceeding a fourth preset threshold for a maximum flow volume; exceeding below a fifth preset threshold for a low temperature; exceeding above a sixth preset threshold for a high temperature; and/or exceeding above a seventh preset threshold for a high pressure.
