It then acts on diaphragm B as nozzle back pressure, the main valve is pushed down by the generated force, and the supply pressure flows out to the downstream side. The air pressure that flows in acts on diaphragm C. While opposing the force generated by diaphragm B it also acts on diaphragm A, opposing the compression force of the setting spring and becomes the set pressure. If the set pressure rises too high, diaphragm A is pushed up, the interval between the flapper and the nozzle widens, the nozzle back pressure drops, the balance of diaphragms B and C is broken, the main valve closes, the exhaust valve opens and the excess pressure from the downstream side is discharged to the atmosphere. In this way fine pressure variations are detected by the nozzle/flapper type pilot mechanism, and precise pressure adjustment is performed. 83 A

//3 Series Specific Product Precautions Be sure to read this before handling the products. Refer to back page 5 for Safety Instructions and pages 387 to 39 for Precautions on every series. Operating Environment Warning. Do not use in an atmosphere having corrosive gases, chemicals, sea water, water, water steam, or where there is direct contact with any of these.. Do not operate in locations where vibration or impact occurs. 3. In locations which receive direct sunlight, provide a protective cover, etc. 4. In locations near heat sources, block off any radiated heat. 5. In locations where there is contact with spatter from water, oil or solder, etc., implement suitable protective measures. Warning Caution Air Supply. Please consult with SMC when using the product in applications other than compressed air.. Do not use compressed air which includes chemicals, synthetic oils containing organic solvents, salt or corrosive gases, etc., as this can cause damage or malfunction. 3. If the drain removal from air filter and mist separator is missed, drain will be flown out to the outlet side and may result in a malfunction of the pneumatic equipment. When removing drain is difficult, use of a filter with an autodrain is recommended.. If the supply pressure line contains drain or dust, etc., the fixed throttle can become clogged leading to malfunction, and therefore, in addition to an air filter (SMC AF series) be sure to install a mist separator (SMC AM, AFM series) and remove drain, etc. periodically. For air quality, refer to Air Preparation Equipment Model Selection Guide on pages and 3. For the maintenance method of the air preparation equipment, refer to the recommended method for the model in use.. Never use a lubricator on the supply side of the precision regulator, as this will positively cause the fixed throttle to become clogged and result in a malfunction. If lubrication is required for terminal devices, connect a lubricator on the output side of the precision regulator. The following may occur if the fixed throttle is clogged or is getting clogged. No output Set pressure drops. Set pressure is unstable. Outlet pressure slowly rises. Warning Warning Caution Caution Maintenance. When the valve guide (refer to construction drawing on page 83) is to be removed during maintenance, first reduce the set pressure to and completely shut off the supply pressure.. When a pressure gauge is to be mounted, remove the plug after reducing the set pressure to. Precautions for only. When remounting the valve guide after removing it for maintenance, tighten the valve guide slowly using a tightening torque of no more than.6 N m. Since the valve guide on this product is made of resin, there is a danger of damage if tightened with a torque exceeding the prescribed value. Handling. When the precision regulator with pressure gauge is used, do not apply impact to the product by dropping it, etc. during transportation or installation. This may cause misalignment of the pressure gauge pointer. Operation. Do not use a precision regulator outside the range of its specifications as this can cause failure. (Refer to specifications.). When mounting is performed, make connections while confirming port indications. 3. Screw a panel nut with the recommended proper torque when mounting onto a panel. Looseness or faulty sealing will occur if tightening torque is insufficient, while thread damage will result if the torque is excessive. Recommended Proper Torque (N m) 3.5 4. If a directional switching valve (solenoid valve, mechanical valve, etc.) is mounted on the supply side of the precision regulator and repeatedly switched ON and OFF, wear of the nozzle/flapper section will be accelerated and a discrepancy in the setting value may occur. Therefore, avoid using a directional switching valve on the supply side. In the event a directional switching valve will be used, install it on the output side of the precision regulator. 5. The accessory pressure gauge is supplied with the precision regulator in the unassembled status. Before using the precision regulator, be sure to install the pressure gauge at the gauge port of the precision regulator. At this time, the recommended tightening torque of the pressure gauge is 7 to 9 N m. 8

//3 Series Specific Product Precautions Be sure to read this before handling the products. Refer to back page 5 for Safety Instructions and pages 387 to 39 for Precautions on every series. Caution Operation 6. Air is normally released from the bleed hole (the hole on the side of the body s mid-section). This is a necessary consumption of air based on the construction of the precision regulator, and is not an abnormality. 7. Make sure to tighten the lock nut after pressure adjustment. 8. There may be pulsation or noise depending on the pressure conditions, piping conditions and ambient environment. In this case, it is possible to improve the problem by changing the pressure conditions and piping conditions. If the problem is not improved, please contact your SMC sales representative. 9. After the pressure is supplied from the upstream side or the set pressure has been adjusted, the set pressure may gradually vary depending on the secular change of internal parts. If the variation in the set pressure has become large, readjust the set pressure using the setting knob.. The set pressure may vary if it is influenced by the variation in ambient temperature or fluid temperature. If the set pressure varies due to the influence of temperature, consider the management of ambient and fluid temperatures. Precautions for 3, 3 only Caution. The supply pressure is relatively high (approx. MPa or more), the set pressure is low (approx.. MPa or less), and when operated with the output side released to the atmosphere, there may be pulsations in the setting pressure. In this kind of situation, operate with the supply pressure reduced as much as possible, or increase the set pressure somewhat and restrict the output line (add and adjust a stop valve, etc.).. The capacity of the output side is large, and when used for the purpose of a relief function, the exhaust sound will be loud when being relieved. Therefore, operate with a silencer (SMC AN series) mounted on the exhaust port (EXH port). The connection is Rc /. Precautions for, 3 (air operated type) only Caution. Since the output types of and 3 series are the same pressure as the input signal pressure, select a type of regulator (general purpose or precision type) for input signal pressure adjustment according to the application.. The screw on the topmost section is a zero point adjustment screw that is locked at the factory. Adjusting the adjustment screw can cause the product to malfunction. Use the product without adjusting the adjustment screw. ARJ AR45 to 935 ARX AMR ARM ARP -A V VEX SRH SRP SRF ITV IC ITVH ITVX PVQ VY VBA VBAT AP 83
