Specific Product Precautions 4
Be sure to read before handling.
Refer to back cover for Safety Instructions, “Handling Precautions for SMC Products”
(M-E03-3) and the Operation Manual for 2 Port Solenoid Valves for Fluid Control
Precautions. Please download it via our website, http://www.smcworld.com
Caution
Maintenance
Warning
1. Filters and strainers
1) Be careful regarding clogging of filters and strainers.
2) Replace filter elements after one year of use, or earlier if
the pressure drop reaches 0.1 MPa.
3) Clean strainers when the pressure drop reaches 0.1 MPa.
2. Lubrication
When using after lubricating, never forget to lubricate continu-
ously.
3. Storage
In case of long term storage after use, thoroughly remove all
moisture to prevent rust and deterioration of rubber materials,
etc.
4. Exhaust the drainage from an air filter periodically.
1. Removing the product
The valve will reach a high temperature when used with high
temperature fluids. Confirm that the valve temperature has
dropped sufficiently before performing work. If touched inadver-
tently, there is a danger of being burned.
1) Shut off the fluid supply and release the fluid pressure in
the system.
2) Shut off the power supply.
3) Remove 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.
Operating Precautions
Warning
1. If there is a possibility of reverse pressure being
applied to the valve, take countermeasures such as
mounting a check valve on the downstream side of
the valve.
2. When problems are caused by a water hammer,
install water hammer relief equipment (accumulator,
etc.), or use an SMC water hammer relief valve
(Series VXR). For details, please consult with SMC.
3. When the pilot type 2 port solenoid valve is closed,
and pressure is applied suddenly due to the
starting of fluid supply source such as pump and
compressor, the valve may open momentarily and
fluid may leak.
4.If the product is used in the conditions in which
rapid decrease in the inlet pressure of the valve and
rapid increase in the outlet pressure of the valve are
repeated, excessive stress will be applied to the
diaphragm, which causes the diaphragm to be
damaged and dropped, leading to the operation
failure of the valve. Check the operating conditions
before use.
