Inlet side piping conditions
The normal size of the piping material’s or equipment’s bore should be equal to or larger
than the port size of this product. The combine sonic conductance of the inlet side’s (P
port side’s) piping or equipment shoule be equal to or larger than the values below.
When the piping is restricted or the supply pressure is insufficient, the main valve will
not switch and air leakage may occur from the R port.
Wiring
Caution
1.
Applied voltage
When electric power is connected to a solenoid valve, be careful to apply the proper
voltage. Improper voltage may cause malfunction or coil damage.
2.
Check the connection
Check if the connections are correct after completing all wiring.
3.
External force applied to the lead wire
If an excessive force is applied to the lead wire, this may cause faulty wiring. Take
appropriate measures so that a force of 30N or more is not applied to the lead wire.
Lubrication
Caution
1.
This product has been lubricated for life at the factory, and does not require any further
lubrication.
2.
If a lubricant is used in the system, use class 1 turbine oil (no additive), ISO VG32. Using
other lubricant may cause damage to the product or malfunction. Once lubricant is utilized
within the system, since the original lubricant applied within the product during
manufacturing will be washed away, please continue to supply lubrication to the system.
Without continued lubrication, malfunctions could occur. If turbine oil is used, refer to the
corresponding Safety Data Sheet (SDS).
3.
Lubrication amount
If the lubrication amount is excessive, the oil may accumulate inside the pilot valve, causing
a malfunction or response delay. So do not apply a large amount of oil.
Air Supply
Warning
1.
Using clear air
Do not use compressed air that contained chemicals, synthetic oils that include organic
solvents, salt, corrosive gases, etc., as they may cause damage or malfunction.
