The invention relates to the technical field of control valves, in particular to a novel pressure compensator, which is characterized by comprising a valve body, a throttling valve core, a spring, a pressure compensator, an adjusting knob, a throttling port passing through the throttling valve core, a throttling port, an inner hole, a screw nail, a carrier rod, an inlet, an outlet and a base. The novel pressure compensator is a pressure compensator arranged at the bottom of the cavity of the valve body; the pressure compensator consists of a throttling valve core, a spring and a base; and the upper part of the pressure compensator is provided with a carrier rod to form a novel pressure compensator. In the novel pressure compensator, medium flows at the inlet and the outlet are controlled under the cooperated action of the throttling valve core, the pressure compensator and the adjusting knob, so that the flow requirement of equipment running pressure is met.
