Abstract
A valve for a fire extinguishing system includes a housing, a flow control apparatus, an actuator apparatus, and a manual override apparatus. The flow control apparatus is disposed in a cavity to prevent or permit flow of the fire extinguishing agent from an ingress aperture to an egress aperture of the housing. The flow control apparatus includes a burst disk clamped between the first and second annular faces and an annular spool axially movable along the longitudinal axis relative to the housing. The actuator apparatus includes a bearing sleeve angularly movable around a longitudinal axis relative to the housing and a latch element operably coupling the bearing sleeve and the annular spool. The manual override apparatus includes a cam operably coupled to the bearing sleeve.
