Internal Pilot Type
Caution
Valve may not operate properly when air supply to P port is not adequate and the supply pressure
to the valve is lower than 0.25 MPa, the minimum operating pressure. Be careful with insuffi cient
supply pressure.
Piping for External Pilot Type
Caution
The product may not operate when the external pilot pressure is insuffi cient due to simultaneous
operation or restricted air piping. In this case, use the check valve (AKH series) with the external
pilot port, change the piping size or adjust the set pressure to provide a constant pressure of 0.25
MPa or more.
