Note 1) Maximum operating frequency for 3 position double pilot check valve is 8Hz.
Note 2) Impact resistance: No malfunction resulted during the impact test using a
drop impact tester. The test was performed one time each in the axial and
right angle directions of the main valve and armature for both energized
and de-energized conditions. (Values quoted are for a new valve)
Vibration resistance: No malfunction resulted during a one-sweep test
between 8.3 and 2000 Hz. The test was performed in the axial and right
angle directions of the main valve and armature for both energized and de-
energized conditions. (Values quoted are for a new valve).
Note 3) If there is vibration or impact, install the valve so that the spool is
perpendicular to the direction of vibration.
If there is no vibration or impact, install the spool valve so that it is
horizontal.
Note 4) Weight is without sub-plate. Sub-plate weight: 0.37 kg.

3 Installation
3.1 Installation
Warning
•
Do not install the product unless the safety instructions have been read
and understood.
3.2 Environment
Warning
•
Do not use in an environment where corrosive gases, chemicals, salt
water or steam are present.
•
Do not use in an explosive atmosphere.
•
Do not expose to direct sunlight. Use a suitable protective cover.
•
Do not install in a location subject to vibration or impact in excess of
the product’s specifications.
•
Do not mount in a location exposed to radiant heat that would result in
temperatures in excess of the product’s specifications.
3.3 Piping
Caution
•
Before connecting piping make sure to clean up chips, cutting oil, dust
etc.
•
When installing piping or fittings, ensure sealant material does not
enter inside the port. When using seal tape, leave 1 thread
exposed
on the end of the pipe/fitting.
•
Tighten fittings to the specified tightening torque.

3.4 Lubrication
Caution
•
SMC products have been lubricated for life at manufacture, and do not
require lubrication in service.
•
If a lubricant is used in the system, refer to catalogue for details.
3.5 Air supply
Warning
•
Use clean air. If the compressed air supply includes chemicals,
synthetic materials (including organic solvents), salinity, corrosive gas
etc., it can lead to damage or malfunction.
Caution
•
Install an air filter upstream of the valve. Select an air filter with a
filtration size of 5 μm or smaller.
3.6 Manual override
Warning
•
Regardless of an electric signal for the valve, the manual override is
used for switching the main valve. Since connected equipment will
operate when the manual override is activated, confirm that conditions
are safe prior to activation.
•
Locked manual overrides might prevent the valve responding to being
electrically de-energised or cause unexpected movement in the
equipment.
3.6.1 Non-locking push type
•
Push on the manual override button (orange) using a small-bladed
screwdriver or suitable tool until the valve switches (ON position).
•
Hold this position for the duration of the check (ON position).
•
Release the button and the override will re-set to the OFF position.
Figure 2.
3.6.2 Push-locking slotted type
3.6.2.1 To lock:
•
Using a small-bladed screwdriver in the slot, push the manual override
button down until it stops.
3 Installation - continued
•
Turn the override button 90° in the direction of the arrow until it stops
(ON position).
•
Remove the screwdriver. The valve will remain switched ON.
Figure 3.
Warning
In this
position the manual override is in the locked ‘ON’ position.
3.6.2.2 To unlock:
•
Place a small-bladed screwdriver in the slot, push down the manual
override button.
•
Turn the override button 90° in the reverse direction of the arrow.
•
Remove the screwdriver and the manual override will re-set to the OFF
position.
3.7 Mounting
Caution
•
Ensure gaskets are in good condition, not deformed and are dust and
debris free.
•
When mounting valves ensure gaskets are present, aligned and
securely in place and tighten screws to torque values as per table
below.

3.8 Electrical circuit
Caution
•
Surge suppression should be specified by using the appropriate part
number. If a valve type without suppression is used, suppression must
be provided by the host controller as close as possible to the valve.
