A dual check and high pressure relief valve that is able to perform the function of a hydrostatic high pressure relief valve and a check valve. The new valve has two poppets separated by a spring that are within two seats within a guide and secured by a plug. By adjusting the seats the relief pressure setting is set. The dual check and high pressure relief valve has three separate passageways that allow fluid flow between different combinations of the passages depending upon the function desired within the hydrostatic circuit. A dashpot is also included between the two poppets to provide positive dampening of the system.
