Description

Overview

The Sealco cab control valve park brake gives manual push pull control of trailer or dolly spring brakes so drivers can safely release or apply the park brake from the cab. In addition, it helps protect the primary air supply by closing when pressure drops below a safe level.

Features

• Manual push pull cab control for trailer and dolly park brake release
• Dedicated exhaust port to vent air quickly when the button is pulled out
• 1/4″ NPT supply, delivery and exhaust ports for standard air brake plumbing
• Robust Sealco construction suited to demanding heavy vehicle service

Specifications and Materials

This cab control valve uses 1/4″ NPT supply and delivery ports so it integrates cleanly into typical trailer and converter dolly air brake circuits. Furthermore, the separate 1/4″ NPT exhaust allows controlled venting when the park brake is applied, and the push pull button suits single hole mounting in a dash or control pedestal.

Part number: AB8512.

Compliance and Safety

This Sealco cab control valve park brake works as part of an ADR compliant air brake system when installers follow the vehicle manufacturer or engineer specification. Always isolate and drain the air system before removing or fitting any valve. Additionally, use appropriate thread sealant on all ports, tighten fittings to the specified torque so leaks are avoided, then perform a full park brake function test and a leak down test before returning the trailer to service.

Trailer Applications

Workshops use this Sealco cab control valve park brake on converter dollies, semi trailers and other heavy combinations that rely on spring brakes for parking. Moreover, its standard 1/4″ NPT ports make it straightforward to retrofit into existing pipework where an older valve has failed.
