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