COLAS: Raise and lower valve

The COLAS® valve can be used to manually raise and lower the deck height of commercial vehicles and trailers. The COLAS® valve takes the place of current systems which require multiple components, fittings and plumbing. An optional automatic reset feature is available with the COLAS® valve. This feature prevents an operator from moving a vehicle while the valve is in use. The COLAS® valve will reset and allow normal operation of the air suspension system.
