Johnson Controls R-4000-3

REGULATOR

The R-4000 Miniature Pressure Regulator is a low volume device used primarily to readjust the set point of pneumatic controllers. The output pressure of the R-4000 varies in proportion to the rotation of the adjusting knob.

Used with a .005 in. or .007 in. R-3170 Series Restrictor, the R-4000 has a barbed fitting for ¼ in. O.D. polytubing for panel mounting (see Fig. 3) and a 4 in. (102 mm) length of polytubing for conduit box mounting (see Fig. 5). Table 1 lists the various output spans available. These spans can be placed anywhere within the pressure ranges and are obtained by proper tab removal from the stop plate as indicated in Table 1. A two-sided dial plate, for direct or reverse applications, is supplied with the regulator.
