The minimum adjustment pressure equals the value 

obtained from the minimum adjustment pressure 

characteristics plus the tank line back pressure of

of the valves stacked to the base plate side of the 

modular valve.

To make pressure adjustment, loosen the lock nut 

and turn the pressure adjustment screw clockwise or 

anti-clockwise. For an increase of pressure, turn the 

screw clockwise. Be sure to re-tighten the lock nut 

firmly after making adjustment to the pressure.

In case of a small flow, the setting pressure may 

become unstable. To avoid this, refer to the 

minimum flow characteristic curve of the next 

page and use the valve within a range as shown 

with.
