Flow rate versus delta pressure (water control valve fully open)—MCS-100

Flow rate versus delta pressure (water control valve fully open)—MCS-200

A minimum water pressure difference of 1.0 to 1.5 bar (15 to 20 psi) between facility supply and return is required. The previous figures give the pressure difference with a fully opened control valve. In operation, the control valve maintains the water flow to the MCS-200/100 by introducing pressure resistance to reduce the flow to accommodate different water temperatures and cooling capacity. Therefore, the pressure loss in operation appears higher than shown in the above figures. However, to have the full scale of water flow
