A gravity-fed, emergency eyewash station includes a flow regulator in the feed line between the solution bag and the dispensing nozzle to maintain a constant flow rate throughout the entire activation time frame. The flow regulator uses a float valve to variably open and close an orifice that feeds the dispensing nozzle. Solution enters the flow regulator from an orifice at the top and leaves from an opening at the bottom. Solution flowing into and out of the regulator quickly reaches an equilibrium state, resulting in a constant flow rate for the entire activation time frame.
