Fluid control valve assemblies for use in fire protection sprinkler systems to control the flow of firefighting fluid to the system sprinklers. The assemblies include a pressure-operated fluid control valve having an internal fluid chamber in which fluid contained therein acts on an internal diaphragm to control the flow of fluid from an inlet to an outlet of the valve. An environment-responsive control device in fluid communication with the internal fluid chamber along a first fluid communication line controls the flow of fluid out of the fluid chamber to initiate actuation of the valve. A fluid-flow latch in fluid communication with the outlet of the valve along a second fluid communication line subsequently controls the simultaneous flow of fluid out of the fluid chamber and the actuation of the valve.

A riser manifold assembly includes a control valve, a first spool pipe, a flow control switch, a check valve, a second spool pipe, and a test and drain valve. An inlet of the first spool pipe being mechanically coupled and fluidly sealed with an outlet of the control valve. The flow control switch being mechanically mounted to the first spool pipe. An inlet of the check valve being mechanically coupled and fluidly sealed with an outlet of the first spool pipe. An inlet of the second spool pipe being mechanically coupled and fluidly sealed with an outlet of the check valve. The test and drain valve being mechanically coupled and fluidly sealed with an auxiliary port of the second spool pipe.

Disclosed are systems and methods for remotely controlling and monitoring water supply systems in buildings. A system can include a sensor to continuously detect building conditions, an electromechanical device to control a water valve located along a water supply for the building, a user computing device to display information about the building conditions, and a computer system to: continuously receive building condition information from the sensor, determine, based on the information, that an emergency has been detected, generate and transmit first instructions that cause the electromechanical device to turn off the water valve, generate and transmit second instructions that cause the user computing device to present information about the emergency in a graphical user interface (GUI) display, receive user input to control the electromechanical device, and generate and return third instructions to control the electromechanical device based on the user input and/or the continuously received sensor information.

A wet piping system modular valve assembly includes a single piece valve body with a check valve within the valve body. The check valve is movable between a closed position and an open position according to a pressure differential across the check valve. A drain valve is removably mounted to the valve body and fluidly connected with the valve body downstream of the check valve. A mechanically independent flow detection switch is removably mounted to the valve body and fluidly connected with the valve body upstream of the drain valve.
