Description

Overview

Height Control Valve With Dump Facility 3/8″ PTC controls ride height in trailer air suspension systems by adding or exhausting air as vehicle load changes. It includes a dump facility, so it also suits dump-capable plumbing layouts where operators need controlled suspension exhaust. The valve reacts to suspension movement while limiting unnecessary air use during small height changes. When the valve sticks, leaks or loses response, the suspension can sit at the wrong height and the system can cycle air more than it should.

Features

• 3/8″ push-to-connect ports for 3/8″ tubing
• Dump facility with high-flow response and minimal dead band
• Universal mounting suits inline or upright chassis installation
• Mechanical valve for trailer air suspension ride height control

Specifications and Materials

Height Control Valve With Dump Facility 3/8″ PTC suits trailer air suspension systems that use 3/8″ push-to-connect plumbing and need a mechanical dump-capable height control valve. It mounts inline or upright to the chassis, so installers can work around frame and bracket space more easily. Max operating pressure: 150psi. Part number: SP0319.

See the manufacturer technical guide

Compatibility and Fitment

Match the port style, tubing size and dump plumbing before ordering. Also check that the lever and linkage can move freely, because the valve needs correct arm travel to fill and exhaust at the right point. 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. 6310BAAA00

Compliance and Safety

Install a pressure protection valve at the reservoir and keep the exhaust end at or below horizontal. Then set the linkage so it does not bind or toggle through full suspension travel. If the system uses a dump circuit, follow the correct plumbing layout for the chosen mounting position and check the valve for leaks after installation.

Trailer Applications

Height Control Valve With Dump Facility 3/8″ PTC suits trailer air suspension systems that need a mechanical height control valve with dump capability and 3/8″ push-to-connect plumbing. It also suits inline or upright chassis mounting where installers need flexibility around brackets and air line routing. Because the valve reacts quickly and controls air use on small movements, it suits ride height correction, valve replacement and general suspension service work.
