forming press clutch and brake control. Since that
time, ROSS has patented several improved versions
of the double valve and expanded its safety product

ELECTRICAL CONNECTORS
Electrical connectors are required to connect the valve solenoids to the drop cords supplying electrical
power.
Each connector can be positioned so that the cord exits upward or to the side. Cords of 6 mm to 10 mm
diameter can be used. Connectors with a light in a translucent housing are also available to serve as
indicator lights. Order connectors by the part numbers given in the chart below.
WIRED CONNECTORS have a 2 meter (6½ ft) cord with three 18 gauge conductors. Cord exits upward,
and is available in either 6 mm or 10 mm diameter.
CONNECTORS for THREADED CONDUIT accept 1/2 inch electrical conduit fittings.

CAUTION:
Do not use electrical connectors with surge suppressors, as
this may increase valve response time when de-actuating
the solenoids.
