The invention relates to a parking and maneuvering valve for trailers having a spring-loaded parking brake. The aim of the invention is to produce a braking system without a trailer braking valve. The invention provides a release unit, a parking unit and an emergency brake unit functionally assigned to the two units. The release unit, parking unit and emergency brake unit are interactively connected so that the parking unit convoys the pressure exerted by the reservoir of the trailer by the emergency brake unit or conveys the pressure exerted by the coupling head &ldquo;reservoir&rdquo; by the emergency brake unit to the spring-loaded parking brake system.

In a brake valve for the operation of the service brake and spring-loaded brake installation of a utility vehicle trailer, a service brake valve (3) and a spring-loaded valve (1) are provided in a common housing (5) in mirror image arrangement. The two valves, operating in a manner known per se, are constructed of identical components and a common ventilation in the form of a ventilation insert (47) in the center of the housing (5). The two valves are fed either from a common reservoir (55) or from separate reservoirs (77, 79) provided for each of the valves, which reservoirs can be refilled through overflow valves (81, 83) without reflux from the line of the trailer holding reserve air.
