Abstract
Provided is a relief valve with an inlet, and outlet, and a backside of a poppet fluidly connected to an input pressure to increasingly close the poppet as a function of input pressure until a prescribed pressure condition is reached. Upon the prescribed pressure condition being reached, the relief valve decreases pressure on the backside of the poppet to open the poppet and allow fluid flow from the inlet to the outlet. Increasingly closing the poppet allows the relief valve to operate under high pressure conditions and repeatedly open and close to reliable seal without significant leakage after thousands of cycles.
