GENERAL

DESCRIPTION

This device is to terminate operation of a 2" to 3Ć1/4" reciprocating type
air motor in the event of a ruptured outlet hose or the pump runs out of
media. For compressed air use only.
Operating Pressure Range 20 Ć 175 p.s.i. (1.4 Ć 12 bar)...
Temperature Range 0_to 180_F(Ć18_to 82_C).........

OPERATION

The AROĆSTOP control valve senses an increased volume of air to the
pump, beyond the preadjusted setting, and shuts off the air supply to
the pump. The runaway" condition may be caused by any of the followĆ
ing: 1.) depleted pumping material, 2.) a ruptured line on the outlet of
the pump, 3.) excessive cavitation in the material supply.

INSTALLATION

The AROĆSTOP valve should be installed in a filtered and regulated air
line. The Filter & Regulator should be no smaller than an Aro Module /
Air 2000 series. Upstream plumbing from the AROĆSTOP valve should
be 1/4" minimum. The Aro 1/4 coupler & connector furnished with
this model is to be installed on the inlet of the AROĆSTOP valve as
shown. Connect the 1/4 female end of the hose to the outlet of the
AROĆSTOP valve. Installing these items as illustrated is recommenĆ
ded. Use one AROĆSTOP valve for each pump. See installation photo
below.
