When using a 4 port valve as a 3 port valve 

The SJ2000/3000 series can be used as normally closed (N.C.) or 
normally open (N.O.) 3 port valves by plugging one of the cylinder 
ports 4(A) or 2(B). However, exhaust ports should be left open. 
It is convenient when a double solenoid 3 port valve is required.

With power saving circuit

 

Compared  to  the  standard  products,  power  consumption  is 
reduced down to approx. 1/3 (in case of SJ3

60T) by cutting the 

unnecessary  wattage  required  to  hold  the  valve  in  an  energized 
state. (Effective energizing time is over 67 ms at 24 VDC.)

 

    
    
    

 
 
 
 
 
 

 

 

 

 

-  When  a  power  saving  circuit  is  installed,  a  diode  to  prevent 

reverse current is not available for 12 VDC spec. Therefore, use 
caution not to connect in reverse. 

- Be careful about the allowable voltage fluctuation since a voltage 

drop  of  about  0.5  V  occurs  due  to  a  transistor.  (Refer  to  the 
solenoid specifications of each valve for details.)   

 

Light Indication 

 

 

When  equipped  with  light/surge  voltage  suppressor,  the  light 
window  turns  orange  when  solenoid  A  is  energized,  and  it  turns 
green when solenoid B is energized.
