Working principle (For ) When the setting knob is turned, the nozzle is closed by the flapper allowing the supply air that flows in from the upstream side to pass through the fixed throttle. 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. i i NBR, other NBR, other NBR, other Stainless steel, NBR Brass, NBR Brass, NBR NBR, other H-NBR NBR NBR NBR NBR NBR NBR Stainless steel Repair kit no.

Series // Specific Product Precautions Be sure to read before handling. Refer to front matters 4 and 4 for Safety Precautions and pages 87 to 9 for Precautions on every series. Warning Caution Warning Warning Caution Air Supply. 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 euipment. When removing drain is difficult, use of a filter with an autodrain is recommended.. If the supply pressure line contains drain or particlate, etc., the fixed throttle can become clogged leading to malfunction, and therefore, in addition to an air filter (SMC Series AF) be sure to use a mist separator (SMC Series AM, AFM). Refer to pages and regarding air uality.. Never use a lubricator on the supply side of the regulator, as this will positively cause the fixed throttle to become clogged and result in a malfunction. If lubrication is reuired for terminal devices, connect a lubricator on the output side of the regulator. Maintenance. When the valve guide (refer to construction drawing on page 555) 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, use a tightening torue of no more than N m. Since the valve guide on this product is made of resin, there is a danger of damage if tightened with a torue exceeding the prescribed value. Handling. Do not apply force when transferring, mounting and dropping the regulator with a pressure gauge. This may cause misalignment of the pressure gauge pointer. Caution Caution 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.. Screw a panel nut with the recommended proper torue when mounting onto a panel. Looseness or faulty sealing will occur if tightening torue is insufficient, while thread damage will result if the torue is excessive. Recommended Proper Torue (N m).5 4. If a directional switching valve (solenoid valve, mechanical valve, etc.) is mounted on the supply side of the 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 regulator. 5. 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. 6. Make sure to tighten the lock nut after pressure adjustment. Precautions for, only. 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 Series AN) mounted on the exhaust port (EXH port). The connection is Rc /. Precautions for, (air operated type) only Caution. Since the output types of and 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 which is locked at the factory and reuires no adjustment for operation. AR45 to 95 V VEX ARX VY AP 56
