Weighing Valves are constructed for installation on railway wagons and are designed to convert weight information or load status into pressure information.

DP1 weighing valves are pneumatic force-measuring valves for continuous load braking, providing an output air pressure proportional to the wagon's load.

DP2 and VTA are two-stage changeover valves for wagons with continuously varying loads, measuring the force in the wagon spring system and controlling a pneumatic load change unit once the predetermined changeover force is reached. 

The valves are applicable to all types of wagon’s spring suspensions and are designed as compact units for limited installation spaces.
