ABSTRACT:
A differential pressure regulator and accompanying system enabling accurate metering of fluid under high-pressure, low-flow conditions. An annular passage within the fluid flow path of the regulator creates an additional pressure drop within the regulator to reduce fluid velocity within the regulator and associated wear problems. A ball and seat mechanism is specially sized with respect to a piston and provides improved accuracy.
