Description

Overview

Cab levelling valve controls air flow for cabin ride height in truck and bus air suspension systems.

The lever-operated design suits conventional air suspension control setups where the valve reacts to suspension movement and adjusts air delivery through the connected air lines.

Features

• Premium original quality cab levelling valve.
• Lever-operated valve with -50° to +50° actuation angle.
• 1/4″ NPTF port threads on both air line ports.
• Version without one-way valve.

Compliance and Safety

Depressurise the air system before removal, then check air line condition, fittings and mounting hardware before installing the replacement valve.

After installation, confirm ride height and check for air leaks through the full operating range.

Trailer Applications

Workshops fit this cab levelling valve to truck and bus cabin air suspension systems that use conventional lever-operated height control.

It suits service work where the existing valve has air leakage, slow height correction, damaged ports or worn lever operation.
