Description
HON 5020 gas pressure regulator with HON 630 pilot
15
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:
Figure
No.

Optical travel indicator with remote control
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.
