Light Indication
Caution
When equipped with indicator light and surge voltage suppressor,
the light window turns red when solenoid a is energized, and it
turns green when solenoid b is energized.

Substrate inside Manifolds
Caution
The substrate inside of manifolds cannot be taken apart.
Attempting to do so may damage parts.
Other Tube Brands
Caution
1. When using other than SMC brand tube, confirm
that the following specifications are satisfied with
respect to the tube outside diameter tolerance.
1) Nylon tubing
Within
±
0.1 mm
2) Soft nylon tubing
Within
±
0.1 mm
3) Polyurethane tubing 0.15 mm, Within −0.2 mm
Do not use tubing which does not satisfy the specified tubing
O.D. accuracy, or tubing with an I.D., material, hardness, or
surface roughness that differs from SMC’s tubing. Please
consult SMC if anything is unclear. It may cause difficulty in
connecting the tubing, leakage, disconnection of the tubing, or
fitting damage.
When used with tubing other than those from SMC, due to
their properties, the KQG2 and KQB2 are not subject to
warranty.
2. When using fittings other than those from SMC, be
certain to confirm that the operating conditions are
such that no problems will arise.

Surge voltage intrusion
With non-polar type 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
valve in a de-energized state may switch over (see Fig. 1).
When installing a breaker circuit for the loading power supply, con-
sider using a 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 Fig. 2).
