Description
The RR100-F30-D includes air valve and regulator functions.
The RR100-F30-D is made of three main components:
The master regulator which sets the pilot pressure.
The solenoid valve which will open or close the system when the
operator actuates the switch key.
The slave regulator which is the main body.
The slave regulator will receive the signal from the master regulator
through the solenoid valve. For pre-engage starters the signal
pressure will come from the master regulator through the solenoid
valve to the pilot “In” port of the air starter drive housing, giving the
signal to engage the drive pinion into the ring gear. After engaging
the drive pinion, air will come out through the “Out” port of the drive
housing and will go to the cap of the slave regulator.

The slave regulator using the pressure signal on top of the upper
piston will force the valve piston off its seat. That allows air to flow
into the control chamber below the upper piston, through the
outlet port of the RR100 valve to the starter motor. Outlet pressure
increases in the downstream system and sensing chamber (under
the upper piston) and applies an upward force on the bottom of
the upper piston. The upper piston and valve piston move upward.
Upward movement stops when the forces below the upper piston
balance the force above the upper piston.
WARNING
Do not use this starter relay valve with natural gas or other
flammable gases.
Operation
Clockwise rotation of screw (1) will open the seat in the master
regulator and will increase the pressure between the master
regulator and solenoid valve (2). Do not try to exceed 11 bar or 160
psig (or slightly higher than the working pressure of the starter).
The pressure you adjust at the slave regulator will be slightly higher
than the working pressure at the starter. In order to easily adjust the
working pressure install a gauge on the gauge port.

The master pressure regulator is designed as a relieving regulator.
When the pressure below the diaphragm reaches 1.5 bars over the
adjusted pressure, the regulator exhausts the excess pressure.
