HON 5020 gas pressure regulator with HON 630 pilot
 The HON 630 pilot delivers a motorization pressure to the actuator assembly that, as a
function of the outlet pressure and the set setpoint, will result in an opening or closing
operation in the actuator assembly.
 The start-up valve is needed exclusively to start the regulating line and is closed during
normal operation.
 The pilot's amplifying valve is used to set the speed of the motorization pressure
changes.
 The load limiting stage guarantees high accuracy even in the event of large inlet pres-
sure changes.
The numbers have the following meaning:

Optical travel indicator
 The regulator is in the closed position when the magnet is located completely behind
the diffuse surface.
 When the travel position is in the open position, this is not a position indicator, but only
shows that the regulator is in operation.
Optical travel indicator with remote control
 The optical travel indication can also be equipped with a remote indication.
 The positions open and closed are switched by means of a reed contact.
 The remote indication is also not a position indicator, but only shows
whether or not the regulator is in operation.
