Description

Overview

Height control valve with dump facility keeps trailer air suspension at its set ride height as load changes through the day. It adds or exhausts air through the suspension circuit, and the dump function suits systems that need controlled air release during loading, unloading or body movement. Universal mounting also gives you flexibility when replacing a worn valve on an existing chassis layout. That matters when the suspension has to recover quickly after dump or after a change in payload.

Features

• Dump version for air suspension systems that use a dump circuit
• 3/8″ push-to-connect ports for common trailer air line setups
• Universal mounting can be fitted inline or upright to the chassis
• High-flow design with minimal dead band for quick height correction

Specifications and Materials

This kit-style valve uses a 3/8″ push-to-connect port layout and suits the Ridewell Extreme Air high-flow valve family used across trailer and heavy vehicle suspension applications. It includes brackets and a 350mm link kit, while the valve family is rated to 150psi maximum operating pressure. Part number: SP0320. See the official Ridewell technical guide for valve family installation and specification details.

Compatibility and Fitment

Match the port size, dump configuration, mounting position and linkage arrangement before ordering. This cross-reference listing means this valve is a suitable replacement for the part numbers and applications shown. Some changes in air line plumbing may be required. 6310BFAB17-3.0, 6310BFAB1730

Compliance and Safety

Exhaust all pressure from the air system before removal or installation, and wear suitable eye protection when working on pressurised suspension components. If the air tank is shared with the brake system, use the required protection valve arrangement and follow the vehicle manufacturer’s service procedure. Check that the linkage moves freely and that the valve exhaust can vent correctly once fitted.

Trailer Applications

This height control valve with dump facility suits trailer air suspension setups that need normal ride height correction in service but also need dump control during loading, unloading or chassis height changes. Because the mounting is universal, it suits replacement work where the existing valve has slowed, leaked or stopped returning the suspension to the set height.
