A self-regulating valve controls the flow of high pressure gas discharging from a gas cylinder in a fire suppression system in response to a detection of a fire within a protected space by a two-step process which reduces the pressure rise within the protected space upon release of the fire suppression gas into the protected space.

Discharge flow control valve

A two-step, self-regulating valve () controls gas flow from a gas cylinder () in a high pressure system. The valve () includes a valve body (), a piston (), a plug (), a valve actuator (), and a piston actuator (). The piston () is movable within the valve body () along an axis between a first and a second position. The plug () is movable within the valve body () along the axis between a valve closed position, a partially open position, and a fully open position. The valve actuator () allows the plug () to move from the valve closed position to the partially open position. The piston actuator () causes the piston () to move from the first position to the second position when a gas pressure in the gas cylinder () is less than a setpoint. When the piston () moves to the second position, the piston () allows the plug () to move from the partially open position to the fully open position.
