The cylinder starts smoothly because jerks are prevented bymeter-in control.Jerkprevention3. To prevent delay due to the pressure gap, air is rapidlyexhausted to decrease the pressure from D to E, after whichthe piston moves at a constant speed. If a speed controller isused instead of the flow valve, exhausting air will take moretime as illustrated by line D-F, resulting in longer stop time ofthe cylinder and a consequent time loss.Quick exhaustWorking strokeReturn stroke2. When the cylinder reaches the stroke end, the quick air chargeby the flow valve rapidly increases the rear side pressure (PH)from A to B. If a speed controller is used instead of the flowvalve, charging air will take more time as illustrated by line A-C, causing delay in the pressure rise.Quick supply4. The cylinder operates at a low pressure required for a return.Low pressureoperation2

Air Saving ValveSeries <strong>ASR</strong> / Series <strong>ASQ</strong>Adjustment Procedure 1Pressure adjustment1. The fixed set pressure type (-F20) does not require adjustmentbecause the pressure is fixed at 0.2 MPa for both the pressurevalve and the flow valve.2. The set pressures of the variable set pressure type pressurevalve and flow valve are adjusted with knob A and knob Brespectively. Turn the knob clockwise to increase the pressureand counterclockwise to decrease the pressure.3. The graduations 1, 2 and 3 correspond to 0.1, 0.2 and 0.3MPa respectively. Align the bottom end of the knob with thegraduated line for adjustment.Knob23Align the bottom end of theknob with the graduated line.The figure illustrates thecase in which the pressure isset at 0.2 MPa.4. Set the same pressure for the pressure valve and the flowvalve (0.2 MPa as the recommended value).5. The inlet side should be supplied with a pressure which ishigher than the set pressure by 0.1 MPa or more.6. Cap the valve after adjustment.Speed control1. The cylinder speed is adjusted with knobs C , D and E . Firsthave all the knobs fully closed and then open them graduallyfor adjustment. Turn the knob clockwise to close (decrease thespeed of the piston rod) and counterclockwise to open(increase the speed of the piston rod).2. Speed adjustment for the working strokeThe speed is adjusted with the pressure valve and the flowvalve.Open knobs C and E gradually until the required speed isachieved. Make sure that knobs C and E are opened by thesame number of rotations.Note 1) If the piston rod jerks, close knob E until the smoothoperation is achieved.3. Speed adjustment for return strokeThe speed is adjusted with the flow valve.Open knob D gradually until the required speed is achieved.4. Be sure to tighten the lock nut after adjustment.Adjustment Procedure 2Pressure adjustmentPressure Valve / Series <strong>ASR</strong>KnobCKnobA1.

(Refer tospecifications.)Consult <strong>SMC</strong> if fluids other than compressed air (included vacuumpressure) are to be used.InstallationPiping1. Preparation before pipingBefore piping is connected, it should be thoroughly blown outwith air (flushing) or washed to remove chips, cutting oil andother debris from inside the pipe.3. Wrapping of sealant tapeWhen screwing together pipes, fittings, etc., be certain thatchips from the pipe threads and sealant material do not get insidethe piping.Further, when sealant tape is used, leave 1.5 to 2 thread ridgesexposed at the end of the threads.WarningAir Supply1. Types of fluidThis product is designed for use with compressed air. Contact<strong>SMC</strong> if a different type of fluid is to be used.Contact <strong>SMC</strong> regarding products for general fluids, to confirmwhich fluids can be used.2. A large amount of condensatePressurized air containing a large amount of condensate maycause malfunction of the pneumatic equipment. An air dryer orwater separator should be installed upstream from the filters.CautionAir Supply3. Drain flushing managementIf the air filter drains are not flushed regularly, the condensatewill flow downstream from the drains, resulting in malfunctionof the pneumatic equipment.In cases where drain flushing will be difficult, use of filters withauto drain is recommended.For detailed information on the quality of compressed air, referto Best Pneumatics Vol. 4.4. Types of airDo not use compressed air containing chemicals, salt, corrosivegases, synthetic oil which includes organic solvents, etc.,which may cause damage or faulty operation.WarningOperating Environment1. Do not use valves where there is direct contactwith, or in atmospheres of, corrosive gases,chemicals, salt water, water or steam.2. Provide shade in locations which receive directsunlight.3. Do not operate in locations where vibration orimpact occurs.4. Do not operate in locations where the productis exposed to direct heat radiation from a heatsource at a close distance.WarningMaintenance1. Maintenance should be performed in accordancewith the procedures in the instructionmanual.Incorrect handling can cause damage or malfunction ofmachinery and equipment, etc.2. Maintenance workCompressed air can be dangerous if handled improperly.Element replacement and other maintenance etc., should beperformed by personnel having sufficient knowledge andexperience pertaining to pneumatic equipment, while alsoadhering to the product specifications.3. Drain flushingCondensate should be flushed from the air filter and otherdrains on a regular basis.4. Pre-maintenance checksWhen the product is to be removed, be sure to shut off thesupply pressure, release compressed air in the pipelines andconfirm an atmospheric release condition before proceeding.5. Post-maintenance checksAfter mounting, repair or renovation, supply compressed airand perform suitable function and leak tests. If an audible leakis detected or equipment does not operate properly, stopoperation and confirm that mounting is correct.6. Disassembly and modification is prohibited.Do not disassemble or modify the main unit.
Pressure Valve Series <strong>ASR</strong> / Flow Valve Series <strong>ASQ</strong>Specific Product PrecautionsBe sure to read before handling.Warning1. The product cannot be used as a stop valve,of which zero leakage is required.The specifications of the product allow a certain degree ofleakage.2. Confirm whether PTFE can be used.The sealing compound contains PTFE (tetrafluoroethylene resin)powder. Make sure that it will not cause any problem in operation.3. Keep the set pressure range of the outletpressure of the pressure valve within 85%that of the inlet pressure.If the value exceeds 85%, the pressure may become unstable,affected by the fluctuation of the inlet pressure.WarningSelectionInstallation1. Confirm that the lock nut is not loose.If the lock nut is loose, there may be dangerous changes inactuator speed.2. The number of opening and closing rotationsof the needle valve and adjustment screwshould be adjusted within the range of thespecifications.Since it has a pull-out stop mechanism, it will not rotate pastthe limit. Confirm the number of rotations for the product beingused, as excessive turning of the needle will cause damage.3. To adjust the speed, start with the needle inthe completely closed position, and thenadjust by opening gradually.When the needle valve is opening, the actuator may jerksuddenly creating a dangerous situation.Moreover, the needle valve is closed by turning clockwise,and opened by turning counterclockwise. Therefore, theactuator speed is reduced by turning clockwise and increasedby turning counterclockwise.When the product is used for an actuator operating vertically,the actuator may lurch depending on the load. For theadjustment method, please refer to “Selection and Adjustment”on page 3 and 4.4. For installation and removal, tighten the bodyB by applying an appropriate wrench to thetwo opposite sides of the hexagon.Using other parts may destroy the valve. For alignment afterinstallation, rotate body A manually.5. Do not use universal type fittings at a positionwhere they are constantly rotated.The fittings may be damaged.6. The valve cannot be used if there are fluctuationsof the load.The piston rod may jerk during operation.7. In case a closed-center solenoid valve is used,switch to the center position only after pressurecharge inside the cylinder at the strokeend is completed.If the pressure charge is insufficient, the piston rod may jerkafter restart.CautionTightening Torque1. The proper tightening torque for pipe fittings is asshown in the table. As a rule, they should be tightened2 to 3 turns with a tool after first tightening by hand.Be careful not to cause damage by over-tightening.Malethread1/43/81/2Proper tightening torqueN•m12 to 1422 to 2428 to 30Handling of One-Touch FittingsCautionWidth across flatsmm172125Nominal size of adjustableangle wrench mm2002002501. Installation and Removal of Tubing for One-Touch Fittings1) Installation of tubing(1) Using tube cutters TK-1, 2 or 3, take a tube having noflaws on its periphery and cut it off at a right angle. Do notuse pinchers, nippers or scissors, etc. The tubing mightbe cut diagonally or flattened, making installationimpossible or causing problems such as disconnectionand leakage. Allow extra length for the tubing.(2) Hold the tubing and push it in slowly, inserting it securelyall the way into the fitting.(3) After inserting the tubing, pull on it lightly to confirm that itwill not come out. If it is not installed securely all the wayinto the fitting, problems such as leakage or disconnectionof the tubing can occur.2) Removal of tubing(1) Push in the release button sufficiently, pressing the collarevenly around its circumference.(2) Pull out the tubing while holding down the release buttonso that it does not pop out. If the release button is notpressed down sufficiently, there will be increased bite onthe tubing and it will become more difficult to pull it out.(3) When the removed tubing is to be used again, first cut offthe section of the tubing which has been chewed. Usingthe chewed portion of the tube as it is can cause problemssuch as leakage or difficulty in removing the tubing.CautionOperating1. The valve cannot be used if the same pressure is required forboth the working and return strokes.The pressure valve and flow valve are designed to save air bythe difference in the operating pressure.2. Install a flow valve on the working side which requires thecylinder output and a pressure valve on the return side. Thecylinder may not operate if the valves are installed on thewrong sides.Working strokeReturn strokePressure ValveSeries <strong>ASR</strong>Flow ValveSeries <strong>ASQ</strong>3. If a closed-centre, exhaust-centre, pressure-centre or perfectsolenoid valve is used and the solenoid valve is set at thecenter position, the cylinder may move to the position wherethe pressure balance and load balance are achieved.12
