Be sure to read this before handling the products.
Refer to back page 50 for Safety Instructions and pages 17 to 19 for 2 Port Solenoid
Valve for Fluid Control Precautions.
Maintenance
Caution
1. Removing the product
1) Shut off the fluid supply and release the fluid pressure
in the system.
2) Dismount the product.
2. Low frequency operation
Switch valves at least once every 30 days to prevent malfunc-
tion. Also, in order to use it under the optimum state, conduct
a regular inspection once a half year.
3. Stoppage of line
When the line is stopped for a long time, clean the valve so
that fluid (paint, ink, etc.) does not solidify or being cured.
4. Prolonged usage
Leakage may occur with fittings and tube material as they
change over time. Additionally tighten union nuts.
Additional tightening should be 1/6 to 1/4 turn.
If leakage occurs even after additional tightening, replace the
sleeve with a new one.
5. Due to the characteristics of the material (Special
FKM), the compression value of the O-rings of the
VCC series is higher. Therefore, when disassembly
or rearrangement of the product is performed, leak-
age may occur if the O-rings are not replaced. If dis-
assembly or rearrangement is performed, replace
the O-rings with new O-rings.
6. If disassembly, rearrangement, or maintenance is
performed, perform sufficient safety checks before
operating the system. In addition, SMC assumes no
responsibility concerning damage caused by meth-
ods other than those described in the catalog and
operation manual.
