3-Port Solenoid Valves Precautions 1
Be sure to read this before handling products.
Design/Selection
1. Confirm the specifications.
Products represented in this catalog are designed only for use in compressed air systems (including vacuum).
Do not operate at pressures, temperatures, etc., beyond the range of specifications, as this can cause damage or malfunction.
(Refer to the specifications.)
Please contact SMC when using a fluid other than compressed air (including vacuum).
We do not guarantee against any damage if the product is used outside of the specification range.
2. Actuator drive
When 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. Effects of back pressure when using a manifold
Use caution when valves are used on a manifold because actuators may malfunction due to back pressure.
For the single acting cylinder, take appropriate measures to prevent malfunction by using it with an individual EXH spacer assembly, a back pressure check valve, or an individual exhaust manifold.
4. Holding pressure (including vacuum)
Since valves are subject to air leakage, they cannot be used for applications such as holding pressure (including vacuum) in a pressure vessel.
5. Not suitable for use as an emergency shutoff valve, etc.
The valves listed in this catalog are not designed for safety applications such as an emergency shutoff valve. If the valves are used in such applications, additional safety measures should be adopted.
6. Release of residual pressure
For maintenance and inspection purposes install a system for releasing residual pressure.
7. Operation in a vacuum condition
When a valve is used for switching a vacuum, take measures to install a suction filter or similar to prevent external dust or other foreign matter from entering inside the valve.
In addition, at the time of vacuum adsorption, be sure to supply a constant supply of vacuum. Failure to do so may result in foreign matter sticking to the adsorption pad or air leakage, causing the workpiece to drop.
8. Regarding vacuum switch valves and vacuum release valves
If a non-vacuum valve is installed in the middle of a piping system that contains a vacuum, the vacuum condition will not be maintained. Use a valve designed for use under vacuum conditions.
9. Ventilation
Provide 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.
- 4 -
10. Extended periods of continuous energization
If a valve will be continuously energized for an extended period of time, the temperature of the valve will increase due to the heat generated by the coil assembly. This will likely adversely affect the performance of the valve and any nearby peripheral equipment. Therefore, if the valve is to be energized for periods of longer than 30 minutes at a time or if during the hours of operation the energized period per day is longer than the de-energized period, we advise using a power-saving circuit valve.
11. Do not disassemble the product or make any modifications, including additional machining.
Doing so may cause human injury and/or an accident.

3-Port Solenoid Valves Precautions 2
Be sure to read this before handling products.
Design/Selection
1. Leakage voltage
Take note that the leakage voltage will increase when a resistor is used in parallel with a switching element or when a
C-R circuit (surge voltage suppressor) is used for protecting a switching device because of the leakage voltage passing through the C-R circuit. The suppressor residual leakage voltage should be as follows.
DC coil 3% or less of the rated voltage
AC coil 8% or less of the rated voltage
2. Solenoid valve drive for AC with a solid state output
(SSR, TRIAC output, etc.)
1) Current leakage
When using a snubber circuit (C-R element) for surge protection of the output, a very small amount of electrical current will continue to flow even during the OFF state.
This results in the valve not returning. In a situation where the tolerance is exceeded, as in the above case, take measures to install a bleeder resistor.
2) Minimum allowable load amount (Min. load current)
When the consumption current of a valve is less than the output’s minimum allowable load volume or the margin is small, the output may not switch normally. Please contact
SMC.
3) Solenoid valve with full wave rectifier circuit
When the solenoid valve built-in full wave rectifier circuit with AC specifications is used, a return failure of the solenoid valve may occur depending on the kind of triac output circuit. Carefully check this point when selecting a
SSR or sequencer.
For details, contact the SSR or sequencer manufacturer.
3. Surge voltage suppressor
1) The surge voltage suppressor built into the valve is intended to protect the output contacts so that the surge generated inside valve does not adversely affect the output contacts. Therefore, if an overvoltage or overcurrent is received from an external peripheral device, the surge voltage protection element inside the valve is overloaded, causing the element to break. In the worst case, the breakage causes the electric circuit to enter short-circuit status. If energizing continues while in this state, a large current flows. This may cause secondary damage to the output circuit, external peripheral device, or valve, and may also cause a fire. So, take appropriate protective measures, such as the installation of an overcurrent protection circuit in the power supply or a drive circuit to maintain a sufficient level of safety.
2) If a surge protection circuit contains nonstandard diodes, such as Zener diodes or varistor, a residual voltage that is in proportion to the protective circuit and the rated voltage will remain. Therefore, take into consideration the surge voltage protection of the controller. In the case of diodes, the residual voltage is approximately 1 V.
4. Surge voltage intrusion
With non-polar type solenoid valves, at times of sudden interruption of the loading power supply, such as emergency shutdown, surge voltage intrusion may be generated from loading equipment with a large capacity (power consumption), and a solenoid valve in a de-energized state may switch over
(see Figure 1).
When installing a breaker circuit for the loading power supply, consider using a solenoid valve with polarity (with polarity protection diode), or install a surge absorption diode between the loading equipment COM line and the output equipment COM line
(see Figure 2).

5. Operation in low temperature conditions
It is possible to operate a valve in extreme temperatures, as low as –10°C. Take appropriate measures to avoid the freezing of drainage, moisture, etc., in low temperatures.
6. Operation for air blowing
When using a solenoid valve for air blowing, use an external pilot type. Use caution because the pressure drop caused by the air blowing can have an effect on the internal pilot type valve when internal pilot type valves and external pilot type valves are used on the same manifold.
Additionally, when compressed air within the pressure range of the established specifications is supplied to the external pilot type valve’s port, and a double solenoid valve is used for air blowing, the solenoids should be energized when air is being blown.
7. Mounting orientation
The mounting orientation is universal.
8. Initial lubrication of main valve
The following initial lubricant has already been applied to the main valve.
• Rubber seal, spool valve: Grease
Mounting
1. Operation manual
Install the products and operate them only after reading the operation manual carefully and understanding its contents. Also, keep the manual where it can be referred to as necessary.
2. Ensure sufficient space for maintenance activities.
When installing the products, allow access for maintenance and inspection.
3. Tighten threads with the proper tightening torque.
When installing the products, follow the listed torque specifications.
4. 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 coating
Warnings 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.
Piping
1. Refer to the Fittings and Tubing Precautions for handling One-touch fittings
2. Preparation before piping
Before piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove chips, cutting oil, and other debris from inside the pipe.
3. Winding of sealant tape
When screwing piping or fittings into ports, ensure that chips from the pipe threads or sealing material do not enter the piping. Also, if sealant tape is used, leave 1 thread ridge exposed at the end of the threads.
4. Connection of piping and fittings
When screwing piping or fittings into the valve, tighten them as follows.
1) When using SMC’s M5 fittings, follow the procedures below to tighten them.
• Connection thread: M3
First, tighten by hand, then use a suitable wrench to tighten the hexagonal portion of the body an additional
1/4 turn.
The reference value for the tightening torque is 0.4 to 0.5
N·m.
• Connection thread: M5
First, tighten by hand, then use a suitable wrench to tighten the hexagonal portion of the body an additional
1/6 to 1/4 turn.
The reference value for the tightening torque is 1 to 1.5
N·m.
• When using a fitting other than an SMC fitting, follow the instructions given by the fitting manufacturer.
2) For a fitting with sealant R or NPT, first, tighten it by hand, then use a suitable wrench to tighten the hexagonal portion of the body an additional two or three turns. For the tightening torque, refer to the table below.
Connection thread size (R, NPT)
1/8

8 to12
3) If the fitting is tightened with excessive torque, a large amount of sealant will seep out. Remove the excess sealant.
4) Insufficient tightening may cause seal failure or loosen the threads.
5) For reuse
(1) Normally, fittings with a sealant can be reused up to 2 to
3 times.
(2) To prevent air leakage through the sealant, remove any loose sealant stuck to the fitting by blowing air over the threaded portion.
(3) If the sealant no longer provides effective sealing, wind sealing tape over the sealant before reusing. Do not use any form of sealant other than the tape type of sealant.
(4) Once the fitting has been tightened, backing it out to its original position often causes the sealant to become defective. Air leakage will occur.
5. Piping to products

M8 Connector
1. M8 connector types have an IP65 (enclosure) rating, offering protection from dust and water. However please note: these products are not intended for use in water.
Select a SMC connector cable (V100-49-1 ) or a FA sensor type connector, with M8 threaded 3 pin specifications conforming to Nippon Electric Control Equipment Association
Standard, NECA4202 (IEC60947-5-2). Make sure the connector O.D. is 10.5 mm or less when used with the SYJ300 series manifold. If more than 10.5 mm, it cannot be mounted due to the size.
2. Do not use a tool to mount the connector, as this may cause damage. Only tighten by hand. (0.4 to 0.6 N·m)
3. The excessive stress on the cable connector will not be able to satisfy the IP65 rating. Please use caution and do not apply a stress of 30 N or greater.
Failure to meet IP65 performance may result if using alternative connectors than those shown above, or when insufficiently tightened.

Flat Ribbon Cable Manifold
・ In the manifold valves, the wiring to the individual valves is provided on a printed circuit board, and the connection to the external wires is consolidated through the use of a flat ribbon cable.
・ A single MIL flat ribbon cable connects the entire manifold to your power source. This greatly reduces installation time.
Flat Ribbon Cable Manifold
Manifold Internal Wiring
・ For more than 10 stations, both poles of the common should be wired.
・ For single solenoid, connect to the B side solenoid.
・ The maximum number of stations that can be accommodated is
12. For more stations, contact SMC.
・ Only non-polar valves are available for the DC flat cable manifold, therefore negative COM or positive COM wiring of the manifold is possible. The valve does not switch with negative
COM if a Z type is used. Be sure to use a positive COM.

・ If wrong oil is used, completely air blow to remove oil, and replace valve. After valve is replaced, use turbine oil class 1 (ISO VG32).
⑥
・ When a large quantity of drain is given and cannot carry out drain omission surely, install either an auto-drain or a dryer.The valve should be replaced.
⑦ Check voltage. Replace valve (pilot valve).
⑧ Protect the valve so that water does not splash the coil. Replace valve (pilot valve).
⑨
⑩
In case of intrusion of foreign matter, to remove foreign matter by air blow of piping and then replace valve.
Repair or replace actuators.
⑪ After stopping air and re-tighten the bolts.
⑫ Reduce the amount of lubricant to the degree that no oil splashes out of the air exhaust (E) port.
If no improvement is achieved in spite of the above countermeasure, inside of the valve may have some abnomality. In this case, stop using the valve immediately.
If any of followings are carried out, inside of the valve may have some failure. In this case, stop using the valve immediately.
① Voltage out of rated voltage has been used.
② Oil other than the specified one has been lubricated.
③ Lubrication has been stopped intermediately, or lubrication was suspended temporary.
④ Water splashed directely.
⑤ Strong impact was given.
