Manuals Before Operating Equipment.
Use Only With Compressed
Air
This valve
is
for useonfywithcompressedair.
It is not designed
for use with any other power source. NEVER use any other gas
or fluid in the runaway valve.
General
Safety
Any
misuse of the runaway valve, such as overpressurizing,
modifyingparts,orusingwomordamagedparts,cancausethe
valveto ruptureand result inseriousinjuryorpropertydamage.
NEVER alter or modify any part of the runaway valve; doing so
could cause it to malfunction.
CHECK all equipment regularly and repair or replace worn or
damaged parts immediately.
Alwayswearprotectiveeyewear,gloves,clothingandrespirator
as recommended by the fluid and solvent manufacturer.
Alwaysfollowthe
Pressure Relief Procedureinyourseparate
pump manual, before checking, clearing, cleaning, flushing or
servicing any part of the system.
Moving Parts Hazard
To
reduce the risk of serious injury, including pinching or am-
putationoffingersorhands,
NEVERusetherunawayvalveasa

operate the pump wlth the air motor plates or shield removed.
System Pressure
NEVER exceed 120 psi (8.4 bar) MAXIMUM AIR INLET PRES-
SURE
to the vaive, or
the maximum air inlet pressure stated on
your pump.
DONOTexceedthemaximumworkingpressureofanycompo-
nent or accessory used in the system.
Pressure Relief Procedure
To reduce the risk of serious injury, includin injury from
moving
parts,
alwaysfollowthisprocedurew 3, eneveryou
are
servicing the runaway valve.
1. Follow the Pressure Relief Procedure in your sepa-
rate pump manual.
2. Shut off the main air shutoff valve.
IMPORTANT
United States Government safety standards have been adopted under the Occupational Safety and Health Act. These standards -
particularly the General Standards, Pati1910, and the Construction Standards, Part 1926 - should be consulted.
INSTALLATION
Reference letters
and
numbers
in the text refer to Figs 1
and 2 and the Parts Drawing
on page
7.
Install an air filter
(A) to
remove harmful
dirt and moisture
from the compressed air supply. Install a main air shutoff
valve (6) to isolate the runaway valve for servicing. If you
supply your
own
accessories, be sure they are ade-
quately sized and pressure-rated to meet the system's
requirements.
The Typical Installations shown on page 3 are only ex-
amples Contact your Grace representative or Grace
Technical Assistance (see back page) for assistance in
designing a system to meet your particular needs.
install one runaway valve for each pump; the valve will
control only one pump.
WARNING
A bleed-type master air valve (C) is required in
your system.
The bleed-type master air valve re-
lieves air trapped between this valve and the pump
after the air is shut off. Trapped air can cause the
pump to cycle unexpectedly.
Locate the valve
close to the pump.

Installing the Runaway Valve on King'", Bulldoge,
and Senatore Motors
Detail Aof Fig 1 shows the runaway valve (D) used with a
Bulldoge air motor, mounted on a cart. Mounting on a
wall bracket is done the same way. Install the runaway
valve between the air manifold (E) and the air regulator
(F), using necessary adapters. Use the 90" swivel
adapter (G, supplied) to connect the runaway valve out-
let to the air regulator inlet.
lnstalltng the Runaway Valve on Presidente Motors
Details B and C of Fig 1 show the runaway valve (D)
used with a Presidente air motor, mounted on a wall and
on a cart. Install the runaway valve between the air regu-
lator (F) and the bleed-type master air valve (C), using
necessary adapters. Use the 90" swivel adapter (G,
supplied) to connect the runaway valve outlet to the
bleed valve inlet.
Signal Port (See Fig 2)
When the runaway valve trips, the signal port (S) is pres-
surized. This air pressure will operate a pilot-operated
valve to turn on a remote device such as a signal lamp or
alarm. The pressure at this port will be 15% less than the
inbound air pressure.
The volume
ofairpassing
through
the port will be low.
When no remote sensor is being used, this port is
plugged with a screw (3).
