fittings. The pressure relief valve mounted in the
moisture separator assembly opens automatically to
exhaust high-pressure to atmosphere before pressure in
the shell reaches 2, 250 pounds per square inch. The
relief valve reseals, or closes, preventing the further
escape of air when pressure within the shell drops to 1,
950 pounds per square inch.
