Externally piloted sequence valve. Sequence valves produce heat in a hydraulic system. With a pressure setting of 800 psi and resistance in the secondary circuit of 150 psi, there is a 650-psi pressure drop across the valve. This pressure drop results in heat, because its energy does not do useful work. how did chiefs win
