Actuator driveWhen an actuator, such as a cylinder, is to be driven using a valve, take appropriate measures (such as the installation of a cover or the restricting of access to the product) to prevent potential danger caused by actuator operation.3. Intermediate stopsDue to the compressibility of air, it is difficult for this product to make a piston stop at the required intermediate position accurately and precisely.Furthermore, since valves and cylinders are not guaranteed for zero air leakage, it may not be possible to hold a stopped position for an extended period of time.Please contact SMC if it is necessary to hold a stopped position for an extended period of time.4. Effects of back pressure when using a manifoldUse caution when valves are used on a manifold because actuators may malfunction due to back pressure.When a single acting cylinder is operated, take appropriate rmeasures to prevent malfunction by using an individual EXH manifold.5. Holding pressureSince valves are subject to air leakage, they cannot be used for applications such as holding pressure in a pressure vessel.6. Not suitable for use as an emergency shutoff valve, etc.The valves presented in this catalog are not designed for safety applications (e.g. emergency shutoff valve). If the valves are used in such applications, additional safety measures should be adopted.7. Release of residual pressureFor maintenance and inspection purposes install a system for releasing residual pressure.8. VentilationProvide ventilation when using a valve in a confined area, such as in a closed control panel. For example, install a ventilation opening, etc., in order to prevent pressure from increasing inside of the confined area and to release the heat generated by the valve.9. Do not disassemble the product or make any modifications, including additional machining.Doing so may cause human injury and/or an accident. 1. Operation in low temperature conditionsIt is possible to operate the valve in extreme temperatures, as low as 5o C.

If air leakage increases or equipment does not operate properly, stop operation.Check mounting conditions when air and power supplies are connected. Initial function and leakage tests should be performed after installation.5. Painting and coatingWarnings or specifications printed on or affixed to the product should not be erased, removed, or covered up.Please consult with SMC before applying paint to resinous parts, as this may have an adverse effect due to the solvent in the paint.Piping1. Preparation before pipingBefore piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove chips, cutting oil, andother debris from inside the pipe.2. Winding of sealant tapeWhen screwing piping or fittingsinto ports, ensure that chips from the pipe threads or sealingmaterial do not enter the piping.Also, if sealant tape is used, leave 1 thread ridge exposed atthe end of the threads.Piping3. Connection of fittingsFor a fitting with sealant R or NPT, first, tighten it by hand, then use a suitable wrench for the hexagon flats of the body to tighten it a further two or three turns.For the tightening torque, refer to the table below.Connection thread size(R, NPT)Proper tightening torque(N·m)1/4 8 to 12 3/815 to 204. Piping to productsWhen piping to a product, refer to the drawing to avoid mistakes regarding the supply port, etc. Note) Pilot port size of this product is 1/8.This product is universal porting type. N.C type, N.O. type, divider type and selector type can be used.Lubrication1. LubricationThe valve has been lubricated for life by the factory and does not require any further lubrication.If a lubricant is used in the system, use class 1 turbine oil (no additives), ISO VG32.Once lubricant is utilized within the system, since the original lubricant applied within the product during manufacturing will be washed away, please continue to supply lubrication to the system. Without continued lubrication, malfunctions could occur.If turbine oil is used, refer to the Safety Data Sheet (SDS) of the oil.2. Lubrication amountIf too much oil is applied, it may accumulate inside the valve, causing malfunction or response delay. So, do not apply a large amount of oil.Air Supply1. Type of fluidsPlease consult with SMC when using the product in applications other than compressed air. 2. When there is a large amount of drainageCompressed air containing a large amount of drainage can cause the malfunction of pneumatic equipment. An air dryer or water separator should be installed upstream from filters.3. Drain flushingIf condensation in the drain bowl is not emptied on a regular basis, the bowl will overflow. This may cause the malfunction of pneumatic equipment. If the drain bowl is difficult to check and remove, the installation of a drain bowl with an auto drain option is recommended.For compressed air quality, refer to the SMC Best Pneumatics catalog No. 6.4. Use clean airDo not use compressed air that contains chemicals, synthetic oils that include organic solvents, salt, corrosive gases, etc., as it can cause damage or malfunction.1. When extremely dry air is used as the fluid, degradation of the lubrication properties inside the equipment may occur, resulting in reduced reliability (or reduced service life) of the equipment. Please consult with SMC.2. Install an air filter.Install an air filter upstream near the valve. Select an air filter with a filtration size of 5 μm or smaller.3. Take measures to ensure air quality, such asby installing an aftercooler, air dryer, or water separator.Compressed air that contains a large amount of drainage can cause the malfunction of pneumatic equipment, such asvalves. Therefore, take appropriate measures to ensure airquality, such as by providing an aftercooler, air dryer, or water separator.4. If an excessive amount of carbon powder is present, install a mist separator on the upstream side of the valve.If excessive carbon dust is generated by the compressor, it may adhere to the inside of a valve and cause it to malfunction.For compressed air quality, refer to the SMC Best Pneumatics catalog No. 6.Operating Environment1. Do not use in an atmosphere containing corrosive gases, chemicals, sea water, water, water steam, or where there is direct contact with any of these.2. Do not use in an environment where flammable gas or explosive gas exists. Usage may cause a fire or explosion. The products do not have an explosion proof construction.Operating Environment4. The valve should not be exposed to prolonged sunlight. Use a protective cover. Note that the valve is not for outdoor use.5. Remove any sources of excessive heat.6. If it is used in an environment where there is possible contact with oil, weld spatter, etc., exercise preventive measures.1. Temperature of ambient environmentUse the valve within the range of the ambient temperature specification of each valve. In addition, pay attention when using the valve in environments where the temperature changes drastically.2. Humidity of ambient environment• When using the valve in environments with low humidity, take measures to prevent static.• If the humidity rises, take measures to prevent the adhesion of water droplets on the valve.Maintenance1. Perform maintenance and inspection according to the procedures indicated in the operation manual.If handled improperly, human injury and/or malfunction or damage of machinery and equipment may occur.2. Removal of equipment, and supply/exhaust of compressed airBefore components are removed, first confirm that measures are in place to prevent workpieces from dropping, run-away equipment, etc. Then, cut off the supply air and electric power, and exhaust all air pressure from the system using the residual pressure release function.When the equipment is operated after remounting or replacement, first confirm that measures are in place to prevent the lurching of actuators, etc. Then, confirm that the equipment is operating normally.3. Low-frequency operationValves should be operated at least once every 30 days to prevent malfunction. (Use caution regarding the air supply.)4. If the volume of air leakage increases or the valve does not operate normally, do not use the valve.Perform periodic maintenance on the valve to confirm the operating condition and check for any air leakage.1. Drain flushingRemove drainage from the air filters regularly.2. LubricationOnce lubrication has been started, it must be continued.Use class 1 turbine oil (with no additives), VG32. If other lubricant oil is used, it may cause a malfunction.Please contact SMC for suggested class 2 turbine oil (without additives), ISO VG32.VTA/VOA325 SeriesSpecific Product Precautions (1)Be sure to read this before handling the products.Breathing hole1. The bottom of the solenoid valve has a breather hole for the main valve. Take proper measures to prevent this hole from being blocked as this will lead to a malfunction.∗ Ordinarily, when the solenoid valve is mounted on a metal surface, it can breathe through the breather hole, via the breather groove. However, in particular, if the surface to be mounted is made of the rubber, the rubber could deform and block the hole.2. Make sure that dust and/or other foreign materials do not enter the valve from the unused port (e.g. exhaust port).Manifold specificationManifoldFor more than 4 stations, supply air from both P ports on . For common exhaust type, exhaust from both R ports.MountingWhen mounting valves on the manifold base, the mounting orientation is decided. If it is mounted in the wrong direction, connected equipment may malfunction.Changing from N.C. to N.O.The valves are assembled as N.C. valves at the time of shipment. By removing the two retaining screws from the desired valves, and rotating each valve body 180° and reassembling it on the manifold base, it is possible to reassemble an N.C. valve as an N.O. valve. (When doing so, make sure that a gasket is attached to the mounting surface of the valve.) Properly tighten the screws. The tightening torque of the retaining screws is 3 N·m.A single valve unit port locationBottom of the valveCountermeasuresIf any of the examples below are applicable,there may be an internal problem with the valve.Stop using the valve immediately.5. Foreign matter such as condensate or dust has entered the product.6. Other than those specified, if precautions on the operation manual apply.1. The oil supplied was not the specified type.2.
