Description

Overview

The Wabco eTASC raise lower valve 12mm is a 12V dual-circuit air suspension control valve for WABCO trailer EBS and iEBS systems. It also gives the operator manual raise and lower control while retaining electronic suspension integration and return-to-ride-height capability.

Features

• 12V eTASC operation for trailer air suspension control
• Dual-circuit layout with a dedicated test connection
• Three Ø12 x 1.5 air connections for the main pneumatic circuits
• Locks on lowering, while the lifting position does not lock

Specifications and Materials

Ports 1, 22 and 24 use Ø12 x 1.5 connections. Port 26 uses M16 x 1.5 with the test connector, while Port 3 is the exhaust. Protection class is IP6K/9K and overall size is 196 x 107 x 97mm.

Part number: 463-090-500-0.

Compatibility and Fitment

Before ordering, check the 12V electrical system, three Ø12 x 1.5 air connections, test port and dual-circuit layout. However, the main mismatch risk is selecting an 8mm or M16 eTASC variant from the same valve family.

Compliance and Safety

Because eTASC can raise or lower the vehicle with the ignition switched off, ECAS height monitoring does not intervene in that state. Where maximum-height prevention is required, use the appropriate mechanical or pneumatic height-limiting arrangement and confirm correct operation after installation.

Trailer Applications

In service, workshops use the Wabco eTASC raise lower valve 12mm on air-suspended trailers with compatible WABCO EBS or iEBS control. It then supports manual body-height changes for loading, docking and service work, followed by return to ride height.

Why Choose ICS Trailers

This eTASC variant needs the 12V supply, Ø12 x 1.5 air connections and test-port arrangement matched correctly. Before you order, ICS Trailers can help compare old valve markings, photos, port layout and suspension details.

• Match surrounding air suspension components and connecting fittings to the repair
• Use existing markings and cross-reference numbers to narrow down similar eTASC variants
