A valve actuator of a cooling valve is configured to control cooling water in a thermal management system for cooling a fuel cell. The valve actuator includes a motor including a rotor, a stator, and a motor housing, a gear assembly including a gear housing and being connected to a valve rotation shaft of a valve plate configured to control a passage of cooling water, a motor rotation shaft configured to rotate the rotor is connected to the gear assembly, a first underwater bearing disposed between the valve rotation shaft and the gear housing, and a second underwater bearing is disposed between the motor rotation shaft and the gear housing. Cooling water introduced into the cooling valve is introduced into the motor housing and the gear housing to cool the gear assembly and the motor.
