SAFETY DATA
Hazardous machinery
can cause serious
personal injury or
property damage.
Failure to set the vehicle emergency
brake and chock wheels before
performing service can cause severe
personal injury or property damage.
Hazardous
machinery can
cause serious
personal injury.
Failure to disconnect and lockout
electrical power or engine drive before
attempting maintenance can cause
serious personal injury or death
Hazardous fluids can
cause fire, serious
personal injury or
property damage.
All fluids pumped must be compatible
with piston material. Incompatibility
can cause fire, serious personal injury
or property damage.
Hazardous pressure
can cause personal
injury or property
damage.
Disconnecting fluid or pressure
containment components during pump
operation can cause serious personal
injury, death or major property damage
Hazardous or toxic
fluids can cause
serious injury.
If pumping hazardous fluids, the system
must be flushed and decontaminated
prior to performing service or
maintenance.
Hazardous pressure
can cause serious
personal injury or
property damage.
Failure to relieve system pressure prior
to performing pump service or
maintenance can cause personal injury
or property damage.
NOTICE:
Installation and maintenance shall be performed by
qualified technicians only, following the appropriate
procedures and warnings as presented in this manual and
the appropriate pump installation, operation, and
maintenance instructions.

INSTALLATION
The Blackmer Air Valve is a piston type actuator (see parts
list drawing on page 7). The air valve is designed to work
with a flow sensing pilot valve (air or electric) which puts
pressure behind the piston when the nozzle is open and fluid
is flowing. This permits high pressure operation of the pump.
When the nozzle is closed and flow is stopped, the flow
sensing pilot valve relieves the actuating pressure from
behind the piston and the pump will automatically go into low
pressure bypass.
Approximately 70 psi (4.8 bar) minimum air pressure is
required to properly operate the air valve control system. Air
pressure MUST NOT exceed 125 psi (8.6 bar).
PRE-INSTALLATION CLEANING
Foreign matter entering the pump WILL cause extensive
damage. The pump and the surrounding area MUST be
cleaned prior to attempting air valve installation.
NOTICE:
A preset, spring loaded air check valve must be installed
in the vehicle air supply line to ensure minimum safe air
pressure for the brake system.
