TECHNICAL
DATA
Select the same nominal size safety check valve as the
hose size leading to the respective air tool. Air
flow must be in the direction of the arrow marked on the
saftey check valve. A safety check valve should
be installed for use before each air tool.
The actual length of hose from safety check valve to
air tool must not exceed a certain length depending upon
the inlet pressure. The volume of air flow (CFM)
through an air line will vary according to its length.
A longer line will offer more resistance to flow and thus
reduce the volume. The length of the hose extending from
the safety check valve to the air tool must, therefore,
be limited to a certain length to insure sufficient flow
to trigger the safety check valve in case of a break.
INSTALLATION
This unit is to be installed on compressed air lines
leading to pneumatic tools.
NOTE: Nominal sizes of valve and connecting hose
must be consistent. i.e. 1/4" valve to be used with
1/4" hose.
CAUTION: Do not reduce safety check valve with
bushings for use with a smaller air line. If this
is done, there will not be sufficient CFM flow during
a line break to shut off the air flow through the safety
check valve. |
