Pilot pressure/external pilot type

    

When the operating pressure is less than 0.2MPa, adjust 

the pilot pressure and external pilot pressure to 0.2MPa.   

When the operating pressure is 0.2MP or more, adjust the 

pressure to the value the same as the operating pressure. 

 

Handling precautions

    

1. As the PE port is the exhaust port of the pilot valve, do 

not plug or restrict it.   

2. The X port is the pressure supply port of the pilot valve 

and PE port is the exhaust port of the pilot valve. Pay 

attention that these ports should be connected correctly.
