Description
The direct-acting proportional valve type 2875 can be used as actuator for process control. Due to a more elastic seat seal, the valve is sealed 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.).

Hints
The kv factor indicates the volume flow through a valve, measured in litres/min at 1 bar and at a water temperature between 5 and 30°C. The QNn factor indicates the gas volume flow, measured in litres/min
