COMBINATION FILL
VALVE AND BACKFLOW
PREVENTER
Series 911 combination fill valve and backflow
preventer consists of a Model 9D backflow
preventer and Model 1156F feed water
pressure regulator in one pre-assembled unit.
This valve is designed for use on boiler feed
lines to provide make-up water to the boiler
and prevent backflow when supply pressure
fails.
Pressure-Temperature
Maximum Temperature: 212 degrees F (100
degrees C)
Maximum Working Pressure: 100 psi (6.9
bars)
Adjustment Range: 10-25 psi (68.7 - 172.4
kPa) set at 15 psi (103.4 kPa)

PRESSURE REDUCING
BACKFLOW PREVENTER
Combines the quality pressure reduction of
the Cash Acme A-89 Pressure Reducing
Boiler Feed Valve with the effective backflow
prevention of the Cash Acme BFP Double-
Check Backflow Preventer. Reduces system
pressure down to 14 psi while preventing the
back-siphonage of contaminated water into
the potable water supply. Threaded (NPT)
inlet and outlet connections.
For smaller boiler feed lines where pressure
control and back-siphoning of water are
issues.
