Description
The direct-acting proportional valve type 2873 can be used as actuator for process control Due to a more elastic seat seal, the valve is tightly closed in the range of the nominal pressure related to the nominal diameter (integrated shut-off function). The actuator anchor of the valve is mounted in a friction-less manner, WAS leads to an extraordinary actuating behavior. This valve is particularly suitable for demanding control tasks (high setting range, dry gases, etc.).
