Abstract
Systems and methods of an integrated fluid control valve and valve actuator assembly are provided. The assembly includes a pressure operated fluid control valve for controlling the flow of liquid from a liquid supply piping system into a sprinkler piping system of a fire protection system when transitioning the fire protection system from a stand-by state to an actuated state. The control valve defines a valve chamber for holding a pressurized fluid to prevent the flow of fluid through the control valve. A valve actuator is coupled to the fluid control valve housing for setting of the fluid control valve in an unactuated ready state and for operating the fluid control valve automatically and/or manually. The assembly has a common supply port to supply fluid to the control valve and the actuator and a common discharge port connected to multiple devices that can place the system in an actuated state.
