Countermeasures 

(1) 

Connect wires correctly. 

(2) 

Replace the part. 

(3) 

Replace the part or connect wires correctly. 

(4) 

Replace the valve (the pilot valve) with a new one. 

(5) 

Adjust the pressure so that pilot pressure is within the specified range during operation. 

(6) 

  If incorrect oil has been used for lubrication, remove the oil with air blow, and replace the valve with a new one. 

If a lubricant is used in the system after the replacement of the valve, use turbine oil Class 1 (with no 

additive) ISO VG32. 

  If there is a large amount of condensate or condensate cannot be removed completely, mount an auto 

drain or install a dryer and replace the valve. 

(7) 

Check the voltage, and replace the pilot valve. 

(8) 

Protect the valve especially the coil to prevent it from being exposed to water. 

(9) 

If air leakage is caused by foreign matter, remove foreign matter in the piping by air blow and replace the 

valve. 

(10) 

Repair or replace the actuators. 

(11) 

Stop the air and additionally tighten the bolt.Check whether there is vibration or impact which has caused the 

loosening of the bolt. Install damping rubber so that the product is not affected by the vibration and impact. 

(12) 

Reduce the amount of lubrication to the amount at which the oil does not splash from the exhaust port (P

 

   

port). 

(13) 

Adjust the voltage so that the voltage at the time of operation stays within the specification range. 

(14) 

Ensure proper supply pressure and pilot pressure. 

(15) 

Stop the air consumption. Check where the air is leaking from, and stop the air leakage. 

(16) 

Install a tank on the supply side to stabilize the supply pressure. 

(17) 

Install a tank on the pilot pressure supply side to stabilize the pilot pressure. 

 
 

If the countermeasures above are not effective, there may be a problem with the valve. In that case, stop using the valve 

immediately. 

 

If any of the examples below are applicable, there may be an internal problem in the valve. In that case, stop using the 

valve immediately. 

 

  The voltage used was not the rated voltage. 

  The oil supplied was not the specified type.     

  Lubrication was stopped during operation. Or, lubrication was interrupted temporarily. 

  The product was directly exposed to water.   

  Strong impact was applied. 

  Foreign matter such as condensate or dust has entered the product. 

  Other than the cases mentioned above, any usage which falls under the precautions in this Operation Manual. 

  

If the product malfunctions, please return the valve as it is.
