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
