ITEM NAME:   VALVE,SAFETY RELIEF
DEFINITION:  A valve designed to automatically release excessive pressures. It is
             actuated by static pressure upstream of the valve and is used as a
             safety valve or relief valve, and may be set to close at a
             predetermined pressure. It is not designed for regulation of
             continuously fluctuating loads. It may be inline or cartridge
             (manifold) design. Excludes VALVE (1), RELIEF, PRESSURE AND
             TEMPERATURE.
