1. 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 SMC’s “Compressed Air Cleaning Systems” catalog regarding air quality.
2. 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 required for terminal devices, connect a lubricator on the output side of the regulator.
Air Supply
Caution
1. When the valve guide (refer to construction drawing on page 14-5-8) is to be removed during maintenance, first reduce the set pressure to “0” and completely shut off the supply pressure.
2. When a pressure gauge is to be mounted, remove the plug after reducing the set pressure to “0”.
Maintenance
Warning
Operation
Caution
1. When remounting the valve guide after removing it for maintenance, use a tightening torque of no more than 0.6 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.
1. The supply pressure is relatively high (approx. 0.5 MPa or more), the set pressure is low (approx. 0.1 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.).
2. 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 1/2.
1. Since the output types of IR2120 and IR3120 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.
2. The screw on the topmost section is a zero point adjustment screw which is locked at the factory and requires no adjustment for operation.
Warning
1. 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 auto-drain is recommended.
1. Do not use a precision regulator outside the range of its specifications as this can cause failure. (Refer to specifications.)
2. 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.
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.

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.

1. When a system hazard can be expected due to a drop in vacuum pressure caused by power loss or vacuum pump trouble, install a safety circuit and configure the system so that it can avoid the danger.
2. When a system hazard can be expected with a malfunction of the vacuum regulator, install a safety circuit and configure the system so that it can avoid the danger.
Handling
Warning
1. When installing a pressure gauge on an existing regulator, be sure to reduce the set pressure to 0 (atmospheric pressure) before removing the plug.
2. Do not remove the body screw while the negative pressure is applied.
3. Before removing the valve guide for inspection, reduce the set pressure to 0 (atmospheric pressure) and also shut down the vacuum pump pressure completely.
Caution
1. Do not use valves in such environments where corrosive gases, chemicals, or brine or water or steam is airborne, or where valves can be directly exposed to any of those.
2. Do not use in locations influenced by vibrations or impacts.3. This vacuum regulator always uses atmospheric air, therefore,
do not use in dusty environments.4. In locations which receive direct sunlight, provide a protective
cover, etc.5. In locations near heat sources, block off any radiated heat.
Operating Environment
1. This vacuum regulator is not to be used for adjusting vacuum pump pressures.
2. Note that an ejector’s flow rate is smaller than that of the vacuum regulator, and therefore, it is not suitable as a “vacuum supply”.
Vacuum Supply
1. These products are designed for use with air. Please contact SMC if any other fluid will be used.
2. Do not use air which includes chemicals, synthetic oils containing organic solvents, salt, or corrosive gases, etc., as this can cause damage or malfunction.
Air Supply
1. Connect piping to the port with “VAC” indication (upper right of the port) for connection to the vacuum pump.
2. To adjust the pressure, turn the knob to the right for changing “atmospheric pressure to vacuum pressure” and to the left for changing “vacuum pressure to atmospheric pressure”.
3. When adjusting pressure, do not touch the lateral hole in the mid-section of the body and the lateral hole (atmospheric air suction hole) below the “VAC” indication.
4. When locking the handle after setting the pressure, press down the knob until the orange band is hidden and a click is heard. On the other hand, when unlocking the handle, pull it up until the orange band is visible and a click is heard.
5. This vacuum regulator is for use with negative pressure only. Be sure that positive pressure is not applied instead. In the event that positive pressure is applied, the vacuum regulator will not be damaged; however, the main valve of the pressure adjustment valve will open and positive pressure will enter the vacuum pump. This may cause malfunction of the vacuum pump.
6. When the capacity of the vacuum pump is relatively small or when the inside diameter of the piping is small, a change in the set pressure (the pressure difference between the non-flow and flow conditions) may be large. In this case, change the vacuum pump or the inside diameter of the piping. When changing the vacuum pump is not possible, add a capacity tank (the capacity depends on the operating conditions) to the VAC side.
7. The pressure response time after opening and closing of valves (such as solenoid valves) is influenced in large and small measures by the internal capacity of the setting side (includes piping capacity). Since the vacuum pump capacity also affects the response time, consider all these points when operating.
8. When using a pressure gauge upside down like Fig. (1), it may result in a shifting of the zero point reading. Make sure to use it in the direction like Fig. (2).

When the handle is turned to the right, the adjusting spring’s generated force pushes down the diaphragm and the main valve. This connects the VAC side and SET side, and the degree of vacuum on the SET side increases (becomes closer to an absolute vacuum). Furthermore, the SET side vacuum pressure moves through the air passage into the vacuum chamber, where it is applied to the top side of the diaphragm and counters the adjusting spring’s compression force; and this adjusts the SET side pressure. When the degree of vacuum on the SET side is higher than the designated setting value (becomes closer to an absolute vacuum), the balance between the adjusting spring and the SET side pressure in the vacuum chamber is lost, and the diaphragm is pushed up. This causes the main valve to close and the atmospheric intake valve to open, which lets atmospheric air into the SET side. When the adjusting spring’s compression force and the SET side pressure are balanced, the SET side pressure is set. Also, when the degree of vacuum of the SET side pressure is lower than the designated setting value (becomes closer to the atmosphere), the balance between the adjusting spring and the SET side pressure of the vacuum chamber is lost, and the diaphragm is pushed down. This causes the atmospheric intake valve to close and the main valve to open, which lets air into the VAC side. When the adjusting spring's compression force and the SET side pressure are balanced, the SET side pressure is set.
