Instructions
The minimum adjustment pressure equals the value obtained from the minimum adjustment
pressure characteristics plus the tank line back pressure of this page. This back pressure
should include the value of the T-line pressure drop characteristics 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
.
