Rotate anticlockwise to increase the flow rate.CONFIGURATIONS (see hydraulic symbols table)— Configuration “SA”: Allows the flow control exiting from the actuator on line A.— Configuration “D”: Allows independent control of the flow exiting from the chambers A and B of the actuator.— All the configurations have a built-in check valve that allows free reverse flow (cracking pressure of 0,7 bar).PERFORMANCES (measured with mineral oil of viscosity 36cSt at 50°C)HYDRAULIC SYMBOLSMaximum operating pressure bar 350Maximum flow rate l/min 250Leakage flow with restrictor closed l/min ≤ 0,5Check valve opening pressure bar 0,7Ambient temperature range °C -20 / +50Fluid temperature range °C -20 / +80Fluid viscosity range cSt 10 ÷ 400Fluid contamination degreeAccording to ISO 4406:1999class 20/18/15Recommended viscosity cSt 25Mass:QTM7-SAQTM7-Dkg7,357,764 410/112 ED 1/2

For these fluids, use NBR seals. For fluids HFDR type(phosphate esters) use FPM seals (code V). For the use of other kinds of fluid such as HFA, HFB, HFC, please consult our technicaldepartment. Using fluids at temperatures higher than 80 °C causes a faster degradation of the fluid and of the seals characteristics.The fluid must be preserved in its physical and chemical characteristics.4 - OVERALL AND MOUNTING DIMENSIONSdimensions in mm1 Mounting surface with sealing rings:4 OR type 3087 (21.89x2.62)2 ORM-0100-20 (10x2)2 Countersunk hex adjustment screw: spanner 8(standard)Rotate anticlockwise to increase the flow3 Locking nut: spanner 244 Adjustment knob (option): KRotate clockwise to increase the flowDUPLOMATIC OLEODINAMICA S.p.A.20015 PARABIAGO (MI) • Via M.
