ABSTRACT:
A high pressure fluid flow control valve that can accurately regulate the volume of fluid flow through the valve in discrete steps by means of a ratchet mechanism associated with a rotatable shaft. The rotatable shaft has a sealing surface on one end for mating with a sealing surface on the output port to close the output port or open it as the shaft is rotated. The shaft is threadedly engaged with the body portion such that it can be rotated a limited portion during opening the valve so that it cannot be accidentally rotated out of the body portion and the valve disassembled. A bleed valve is associated with the hollow chamber to limit the maximum pressure in the valve chamber.
