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.

A head adapter for a fire sprinkler includes a body defining a volume. The body has an elbow shape and includes a first opening that couples with a fluid supply line and provides fluid communication between the fluid supply line and the volume of the body and a second opening that provides fluid communication between the volume of the body and the fire sprinkler. The second opening includes a gasket. The body also includes a cap coupled with the open second end of the body such that the gasket is disposed between the cap and the volume. The cap couples the body to the fire sprinkler to provide fluid communication between the fluid supply line and the fire sprinkler. The volume of the body is shaped such that fluid from the fluid supply line is directed to the fire sprinkler.

In one implementation, a computer-implemented method includes receiving, at a computer system, information that indicates that a fire has been detected in a building and that a fire suppression system within the building has begun dousing the fire; monitoring sensor information from one or more sensors located within the building; determining, by the computer system and based on the sensor information, whether the fire has been extinguished; activating, in response to determining that the fire has been extinguished, a feature to turn off a water supply to the building, the feature being presented on a computing device for a user who is associated with the building; receiving, after activating the feature and from the computing device, a command to turn off the water supply; and transmitting, by the computer system, a control signal that causes an electromechanical device to close a water valve within the building.

Fire protection systems and methods of fire protection systems for protection of a stored commodity. The systems and methods included a plurality of fluid distribution devices disposed above the stored commodity and configured for selective identification and controlled actuation in response to a fire. The systems have a hydraulic demand defined by at least one of: i) a hydraulic design area having a minimum operational area of less than 768 square feet; or ii) less than twelve hydraulic design devices.

A combination control and check valve assembly for a wet piping system includes a control valve in the form of a ball valve and a one-way check valve mounted within the flow pathway of the ball valve. A valve actuation assembly is mounted to the valve assembly to selectively rotate the ball valve between the open and closed positions thereof. The valve actuation assembly is mounted to a first side of the valve assembly and rotationally fixed to the ball, whereby rotation of the valve actuation assembly rotates the ball between the open and closed positions. A side opening is formed in a second side of the valve assembly that is angularly spaced from the first side. The side opening is positioned to align with the fluid flow pathway of the ball valve in the closed position thereof to provide access to the check valve.

An integral valve arrangement may comprise a housing. The housing may comprise a main valve and a relief valve. The main valve may comprise an inlet and a first outlet. The relief valve may comprise a relief inlet in a side wall of the inlet, a relief outlet in a side wall of the first outlet, and a pressure relief system. The inlet and the first outlet may be substantially axially perpendicular. The relief inlet and the relief outlet may be substantially axially perpendicular. The pressure relief system may comprise a body abutting walls of the housing, a relief member disposed within the body, and a lever. The relief member may comprise an interior end and an exterior end. The lever may be rotatably coupled to the exterior end of the relief member by a connecting mechanism.
