  • BALANCED SAFETY RELIEF VALVE
    Publication number: 20060157116
    Abstract: A safety relief valve provides for the equalization of backpressure across a valve spindle by providing for flow of fluid between equal sized upper and lower surfaces of the spindle in order to render the valve set point independent of backpressure, such that opening characteristics are controlled solely by the setting of the valve control spring. A seal preferably formed of TEFLON® is provided to prevent the escape of fluid from the valve body, which would otherwise adversely affect the pressure balance between the upper and lower surfaces.
