Series VHS20/30/40/50
Series VHS2510/3510/4510/5510 Specific Product Precautions 2
Be sure to read before handling. Refer to back cover for Safety Instructions and "Handling
Precautions for SMC Products" (M-E03-3) for 3/4/5 Port Solenoid Valve Precautions.
Operating Environment
Warning
2. Do not use in an explosive atmosphere.
3. Do not use in locations subject to vibration or
impact. Confirm the specifications for each
series.
4. A protective cover should be used to shield
valves from direct sunlight.
5. Shield valves from radiated heat generated
by nearby heat sources.
6. Employ suitable protective measures in loca-
tions where there is contact with water drop-
lets, oil, or welding spatter.
7. Install a silencer into port 3 (R) to prevent the
ingress of dust if there is a lot of dust in the
atmosphere.
If dust enters the valve via port 3 (R) , it may cause air leak-
age.
Maintenance
Warning
1. Perform maintenance procedures as shown
in the instruction manual.
If handled improperly, malfunction or damage of machinery or
equipment may occur.
2. Do not disassemble the product.
Improper handling will cause malfunction or breakage of the
machinery or equipment.
3. When equipment is to be removed, first con-
firm that measures are in place to prevent
dropping of driven objects and run-away of
equipment, etc. Then cut the supply air pres-
sure and electric power, and exhaust all com-
pressed air from the system using its residu-
al pressure release function.
When the equipment is to be started again after remounting
or replacement, first confirm that measures are in place to
prevent lurching of actuators and then confirm that equipment
operates normally.
Caution
1. Once a lubricant is introduced, be sure to con-
tinue lubrication.
If it is discontinued, malfunction may result due to loss of the
initial lubricant. Apply class 1 turbine oil (ISO VG32) as a lu-
bricant. Use of other lubricants may cause malfunction.
Built-in Silencer (Option)
Bronze Sintered Metal Element
Caution
Products made of bronze may contain uneven
color due to the oxidization process of the
atmosphere.
However, this oxidization process occurs in the limited range of
less than 1µm of thickness and is so thin as to not affect the
product characteristics.
The uneven color occurs depending on the storage duration
before utilization (stock as a product, stock in customer)
∗ If this is a problem, please contact SMC so that SMC can
pre-treat them with nickel plating.
