Abstract
A spring-operated relief valve can include a biasing assembly, a valve inlet, a valve seat, and a disc assembly that is biased toward the valve seat by the biasing assembly. A fluid guide, such as a groove or chamber, can be formed at the interface between the valve seat and the disc assembly. The fluid guide can be configured to direct fluid that flows across the valve seat to provide an upward force on the disc assembly during a relief event.
