| description | 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. |
