1. The cylinder starts smoothly because jerks are prevented by meter-in control. Jerk prevention
3. To prevent delay due to the pressure gap, air is rapidly exhausted to decrease the pressure from D to E, after which the piston moves at a constant speed. If a speed controller is used instead of the flow valve, exhausting air will take more time as illustrated by line D-F, resulting in longer stop time of the cylinder and a consequent time loss.
Quick exhaust Working stroke Return stroke
2. When the cylinder reaches the stroke end, the quick air charge by the flow valve rapidly increases the rear side pressure (PH) from A to B. If a speed controller is used instead of the flow valve, charging air will take more time as illustrated by line AC, causing delay in the pressure rise.
Quick supply

4. The cylinder operates at a low pressure required for a return. Low pressure operation

ASR Series/ ASQ Series Selection and Adjustment Install a flow valve on the working side which requires the cylinder output and a pressure valve on the return side. The product cannot be used in cases where the same pressure is necessary for both working and return strokes. In such cases use a speed controller.

Adjustment Procedure 1 Pressure Adjustment
Speed Control
1. The fixed set pressure type (-F20) does not require adjustment because the pressure is fixed at 0.2 MPa for both the pressure valve and the flow valve. 2. The set pressures of the variable set pressure type pressure valve and flow valve are adjusted with knob A and knob B respectively. Turn the knob clockwise to increase the pressure and counterclockwise to decrease the pressure. 3. The graduations 1, 2 and 3 correspond to 0.1, 0.2 and 0.3 MPa respectively. Align the bottom end of the knob with the graduated line for adjustment.
1. The cylinder speed is adjusted with knobs C , D and E . First have all the knobs fully closed and then open them gradually for adjustment. Turn the knob clockwise to close (decrease the speed of the piston rod) and counterclockwise to open (increase the speed of the piston rod). 2. Speed adjustment for the working stroke The speed is adjusted with the pressure valve and the flow valve. Open knobs C and E gradually until the required speed is achieved. Make sure that knobs C and E are opened by the same number of rotations. Note 1) If the piston rod jerks, close knob E until the smooth operation is achieved. 3. Speed adjustment for return stroke The 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.
Knob Align the bottom end of the knob with the graduated line. The figure illustrates the case in which the pressure is set at 0.2 MPa.
2 3
4. Set the same pressure for the pressure valve and the flow valve (0.2 MPa as the recommended value). 5. The inlet side should be supplied with a pressure which is higher than the set pressure by 0.1 MPa or more. 6. Cap the valve after adjustment.

Pressure Adjustment
Speed Control
1. The fixed set pressure type (-F20) does not require adjustment because the pressure is fixed at 0.2 MPa. 2. The pressure at the low pressure side (return stroke side) is adjusted by the pressure valve. 3. The set pressure is adjusted with knob A . Turn the knob clockwise to increase the pressure and counterclockwise to decrease the pressure. 4. The graduations 1, 2 and 3 correspond to 0.1, 0.2 and 0.3 MPa respectively. Align the bottom end of the knob with the graduated line for adjustment. 5. Keep the set pressure as low as possible in order to achieve good air saving effect. 6. Cap the valve after adjustment.
1. The cylinder speed is adjusted with knobs C , F and G . First have all the knobs fully closed and then open them gradually ASR for adjustment. Turn the knob clockwise to close (decrease the ASQ speed of the pistoin rod) and counterclockwise to open (increase the speed of the piston rod). 2. Speed adjustment for the working stroke The speed is adjusted with the pressure valve and the dual speed controller. Open knobs C and G gradually until the required speed is achieved. Make sure that knobs C and G are opened by the same number of rotations. Note 1) If the piston rod jerks, close knob G until the smooth operation is achieved. 3. Speed adjustment for return stroke The speed is adjusted with the dual speed controller. Open knob F gradually until the required speed is achieved. 4. Be sure to tighten the lock nut after adjustment.

ASR /ASQ Series Specific Product Precautions Be sure to read this before handling the products. Refer to back page 50 for Safety Instructions and pages 543 to 546 for Flow Control Equipment Precautions.
Selection
Operating
Warning
Caution
1. Keep the set pressure range of the outlet pressure of the pressure valve within 85% that of the inlet pressure. If the value exceeds 85%, the outlet pressure may become unstable, affected by the fluctuation of the inlet pressure.
The valve cannot be used if the same pressure is required for both the working and return strokes. The pressure valve and flow valve are designed to save air by the difference in the operating pressure. 2 Install a flow valve on the working side which requires the cylinder output and a pressure valve on the return side. The cylinder may not operate if the valves are installed on the wrong sides.

Installation
Warning 1. The number of opening and closing rotations of the needle valve and adjustment screw should be adjusted within the range of the specifications. Since it has a pull-out stop mechanism, it will not rotate past the limit. Confirm the number of rotations for the product being used, as excessive turning of the needle will cause damage.
2. The valve cannot be used if there are load fluctuations. The piston rod may jerk during operation.
3. In case a closed-center solenoid valve is used, switch to the center position only after pressure charge inside the cylinder at the stroke end is completed. If the pressure charge is insufficient, the piston rod may jerk after restart.
4. When the valve is used for an actuator operating vertically, the actuator may lurch depending on the load. For the adjustment method, please refer to page 809.

If a closed-center, exhaust-center, pressure-center or perfect solenoid valve is used and the solenoid valve is set at the center position, the cylinder may move to the position where the pressure balance and load balance are achieved.
