Description

Overview

Immediate response height control valve keeps air-suspended trailer suspension at the set ride height by adding or exhausting air as load changes. Because it uses a non-time delay design, it reacts as the suspension moves instead of waiting through a delayed correction cycle. That makes it a strong fit for trailer air suspension service where ride height needs to recover quickly after loading, unloading or setup changes. Match the valve style, port thread and mounting layout to the existing suspension arrangement before ordering.

Features

• 1/4″ NPT ports for supply and air spring connections
• Non-time delay response for quick ride height correction
• Standard-flow valve-only configuration for immediate response setups
• Mounting style suited to right or left control arm layouts and vertical or horizontal installation

Specifications and Materials

This immediate response height control valve suits trailer air suspension service where a valve-only replacement is required. It uses 1/4″ NPT ports and aligns with the standard-flow immediate response style used on many air suspension layouts. Part number: SP0323. For installation layout and service guidance, see the official installation guide

Compatibility and Fitment

Check port size, plumbing layout, linkage style and installed ride-height arrangement before fitting. 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. 90554241, 90555105

Compliance and Safety

Bleed air pressure from the system before disconnecting lines, and block the vehicle wheels before working under the trailer. Set ride height to the suspension maker’s specification during installation, because incorrect setup can affect suspension position and vehicle performance. Do not mix an immediate response valve with a time-delay valve on the same vehicle, and confirm whether the suspension calls for one or two height control valves before fitment.

Trailer Applications

Use this immediate response height control valve on air-suspended trailers that need quick correction of suspension height after load changes, suspension work or ride-height adjustment. It suits general trailer suspension servicing where the existing system uses a 1/4″ NPT immediate response valve without an integral dump function. It also suits replacement work where worn or sticking ride-height control causes slow recovery or poor height control.
