The Four Circuit Protection Valve separates the single circuit of the air pressure braking system from each other. The pressure can be kept and guaranteed in the braking circuits under excellent conditions if one or more brake circuits break down because of the pressure loss. What’s more, a Four-Circuit Protection Valve also charges for generating compressed air to the braking circuits. Necessary pressure can be conveyed into the two brake circuits for the front and rear axles in advance, which makes the parking brake be released without demanding the available use of all the 4 circuits.
