Datasheet

2. When operating the mechanical operation type
mechanical valves, select the angle and the
maximum speed limit of cam and dog so that valves
do not operate over the following maximum values.
If operated over the maximum values, impact force from cam
and dog will be applied to the actuator, leading to damage of
the actuator or the valve itself.

Max. travel
Over travel. Exces-
sive force is applied
due to the maxi-
mum travel position
being exceeded.
Sufficient travel. The
actuator can reach
the total travel posi-
tion without exces-
sive force being ap-
plied.

Caution
1. If the operating condition is maintained for long
periods of time, it may take some time for the valve
to restart due to the adherence of the seals and
there might be a delay for recovery.
Air Supply
Warning
1. Operable fl uid is either air or inert gas only.
It cannot be used for corrosive gas and fl uid.
Caution
1. Grease is used for the inside of the valves.
Grease may enter into the outlet port of the valve.
2. When using vacuum pressure for the VM100, supply
vacuum pressure to P port.
Operating Environment
Warning
1. Do not operate it in an area in which fl uids such as
oil, coolant, or water splash on it or dust comes in
contact with it.
Because it does not have a waterproof or dustproof construction,
fluids or dust could enter the valve, leading to malfunction.
Therefore, take measures such as providing a protective cover
to prevent direct exposure.
2. Do not expose the product to direct sunlight for an
extended period of time.
Maintenance
Warning
1. Perform inspections on a regular basis as necessary,
such as at the beginning of an operation, to make
sure that the mechanical valve operates properly.
2. Do not disassemble, modify or repair the product.
This may lead to malfunction of equipment, injury and
equipment damage. Please contact SMC for repairs and
maintenance of the product.
