A valve manifold (54) controls hydraulic flow in a hydraulic system for an air compressor unit. The manifold (54) includes a pressure relief valve (1), a cold oil bypass valve (2), a proportional flow valve (3), and an anti-cavitation valve (4). The pressure relief valve (1) diverts flow away from a fan motor (30) when the pressure of hydraulic fluid within the hydraulic system is above a predetermined level. The cold oil bypass valve (2) diverts flow away from a hydraulic cooler (42) when the temperature of hydraulic fluid within the hydraulic system is below a predetermined level. The proportional flow valve (3) diverts flow away from the fan motor (30) when the temperature of hydraulic fluid within the hydraulic system is below a predetermined level. The anti-cavitation valve (4) prevents pressure build up within the hydraulic system when the air compressor unit is shut off. |
