Abstract
A fire-protection system for delivering a fire-control fluid includes a valve having a body with an inlet, an outlet, and a fluid passageway connecting the inlet with the outlet. A seal member is supportable across the passageway to close the passageway. The seal member is supported across the passageway in a sealing position in a pre-activation condition of the valve. The seal member is movable from the sealing position to a fluid-flow position in an activated condition of the valve. The seal member includes a support body having a longitudinal axis, a seat, a leading surface facing in an upstream direction from the seat, and a trailing surface located in a downstream direction from the seat and contoured radially inwardly in the downstream direction. A Belleville washer is mounted on the seat of the support body.
