SERVO VALVES3-STAGE FLOW CONTROL79 SERIESFOR DEPENDABLE, LONG LIFE OPERATION WHERE POSITION, SPEED, PRESSURE OR FORCE CONTROL SYSTEMS HAVE HIGH DYNAMIC RESPONSE REQUIREMENTSWHAT MOVES YOUR WORLDRev. K, December, 2011 The actual flow is dependent upon electrical command signal and valve pressure drop. The flow for a given valve pressure drop can be calculated using the square root function for sharp edge flow value Q calculated in this way should not exceed an average flow velocity of 100 ft/s in ports P, A, B and T. p Q = QN pN Q [gpm] = calculated flow QN [gpm] = rated flow p [psi] = actual valve pressure drop pN [psi] = rated valve pressure dropIf large flow rates with high valve pressure drops are required, an appropriate higher pilot pressure has to be chosen to overcome the flow forces.
