7 307212 Installation Fluid pressure regulators are used for accurate, posi- tive control of the fluid pressure to spray guns, dis- pensing valves or atomizing heads. Regulators installed at circulating line take-offs or pumps are used to reduce main line pressure and maintain the desired fluid pressure to the spray gun or atomizing head.
8 307212 Operation CAUTION The new system must be cleaned and tested thoroughly before admitting fluid to the regulator to avoid contaminants clogging or damaging the regulator . Always use the lowest possible air and fluid pressures for your application.
9 307212 Operation 7. Adjust the fluid regulator to the desired setting. a. Spring Operated Regulators Only (see Fig. 3). The regulator can be adjusted in two ways: Using the male end (B) of the regulator key (24), turn the socket–head adjustment screw (19) fully clockwise .
