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 φ5 or more for this product (with
lock out valve）. If a lock with a shackle of less than φ5 is to be used, please test it on the
actual machine.
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 (P

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.
