Why Choose ICS Trailers

The important checks on this valve are the AE1141 configuration, 24V solenoid control, threaded pneumatic ports and mounting position. If the existing valve has different connections or you are changing to the newer replacement version, send through the old valve markings and installation photos so ICS Trailers can help compare the setup.

• The matching solenoid kit can be identified during electrical or valve service.
• Air line routing and mounting orientation should be checked as part of the replacement.
