Description

Overview

Wabco Raise/Lower Valve gives the operator direct manual control over raising and lowering trailer air suspension with a hand lever. It suits air suspension systems that need manual height adjustment during loading, docking, or workshop setup, and it also supports controlled suspension changes without relying on electronic inputs.

Features

• Hand-operated suspension control valve for manual raise and lower adjustment
• Four M12x1.5 ports plus one M16x1.5 supply port for common trailer air suspension plumbing
• 10 bar maximum operating pressure with integrated check valve on Port 1
• 122mm handle length, 55mm mounting hole spacing, and maximum actuation torque of 7Nm

Specifications and Materials

The Wabco Raise/Lower Valve uses four M12x1.5 control and delivery ports plus one M16x1.5 supply port. It operates to 10 bar, works from -40°C to +80°C, and uses a hand lever that returns suspension control directly to the operator. Mounting is 4 x M8, and the overall valve size is compact enough for common trailer chassis installations. Part number: SP0230.

Compliance and Safety

Use clean, dry air lines and confirm correct plumbing to the supply, control, exhaust, and suspension delivery ports before returning the trailer to service. When the valve is installed, check for air leaks, smooth lever movement, and correct suspension response across the full operating range.

Trailer Applications

The Wabco Raise/Lower Valve suits trailers that use hand-operated air suspension control for loading docks, height changes, and workshop ride-height adjustment. It also suits service replacements where the original valve used the same port arrangement, lever operation, and mounting layout.
