A metal identification tag is attached to each valve. The tag is
secured to the valve using one of the assembly cap screws or
bolts. The part number and serial number of the device is
Device Part Number
Valve Crack
Pressure
stamped into the metal tag in the area indicated. In most cases
a crack pressure will also appear.
REMFRD
Device Serial Number
The part number displayed on the tag is the manufacturers
part number with the letter X added to the end to designate
that the unit is remanufactured. The alpha numeric alpha serial number indicates the date and place of manufacture. The
first letter indicates the month, A (January) through M (December) with the letter I not used. The first pair of digits indicate
the day and the second pair the year. The last character represents the remanufacturing facility. For example, a tag bearing
serial number, H1894X, was built August 18,1994.

Primarily used to deliver hold-off air pressure to the emergency (parking) side of
spring brakes. Prevents compounding of
service (air) and parking (spring) brake
applications through the two way check
valve.
In everyday use, valve shuts off the trailer
service (control) and emergency (supply)
lines before disconnecting the tractor from
the trailer. In emergency, protects tractor
air system by closing both lines to trailer
during break away condition.
