Warning

1. Actuator operation

When using solenoid valve or actuator in the outlet side of tis product, implement

appropriate measures to prevent potential danger caused by actuator operation.

2. Holding pressure

Since the valve might have slight internal leakage, it is not suitable for holding pressure

in a tank or another vessel for a long period of time.

3. 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 for the mentioned applications,

additional safety measures should be adopted.

4. 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.

5. Lock out

We recommend using a lock with a shackle diameter of 5 or more for this product (with

lock out valve）. If a lock with a shackle of less than 5 is to be used, please test it on the

actual machine.

Selection

Warning

1. Confirm the specifications

The products presented in this catalog are designed only for use in compressed air

systems. Do not operate at pressures, temperatures, etc., beyond the range of the

specifications, as this can cause damage or malfunction. (Refer to the specifications.)

Please contact SMC is using for other fluids than compressed air.

2. Operation of closed center solenoid valves

Even if this product is used for closed center solenoid valves or actuator with a load

factor of 50% or more, lurching (quick extension) cannot be prevented.

3. Using a regulator in the outlet side

When mounting a regulator in the outlet side (A port side), use a residual pressure relief

regulator (AR25K to 40K) or a check type regulator. With a standard regulator (AR10

to 60), the outlet side pressure may not be released when this valve is exhausted.

4. Operation of solenoid calves in the outlet side

To operate solenoid valves mounted on this product’s outlet side (A port side), first

confirm that the outlet side’s pressure (PA) has increased to become equal to the inlet

side’s pressure (PP).

5. Operation

The residual pressure release function of this product is for emergency use only;

therefore, avoid the operation in the same manner as ordinary 3 port valves.

6. Using a lubricator

If mounting a lubricator, mount it on the inlet side (P port side), of this product. If mounted

on the outlet side (A port side), back flow of oil will occur and may spurt out of R port.

7. Operation for air blowing

This product cannot be operated for air blowing due to the mechanism that switches

the main valve to be fully open after the outlet side’s pressure (PA) increase to

approximately 1/2 of the inlet side’s pressure (PP).

Caution

1. Leakage voltage

Particularly when using a C-R element (surge voltage suppressor) to protect the

switching element, take note that leakage current will flow through the C-R element,

thus increasing leakage voltage.

AC coil is 8% or less of the rated voltage.

DC coil is 3% or less of the rated voltage.

2. Low temperature operation

Although the valve can be operated at temperature as low as 0 oC, measure should be

taken 0 oC to avoid solidifying or freezing drainage and moisture, etc.
