Due to steadily increasing strip quality, the cooling water valves for the work rolls inside the intermediate roll stands are designed with specially adapted characteristics. The periodically changing width and thickness of the rolling stock is controlled by a high resolution of the characteristic curve. Cooling water control valves for the hot strip rolling stand are used to increase strip quality and continuously cool the rolls.

ARCA bearing pressure control valves with modified characteristic curves are used to increase the service life of the work roll bearings within the production line. They also ensure optimum lubrication of the work roll bearings. Pressure controllers series 902 on the ARCA actuators with supporting volume boosters ensure fast reactions. (Series: 8C, 6N.)
