Start-up-, Directional and Throttle Valves


Trendelkamp start-up, directional and throttle valves are used wherever melt has to be diverted, separated, combined or throttled. The valve bolt is moved to the right valve position by a hydraulic cylinder, an electric drive or manually.

With Valves from Trendelkamp you ensure clean processes, for example. This is because the valves prevent downstream equipment from being contaminated with the start-up material, after a shutdown or a product change.

The valves are also ideally suited for processes that require a start-up period of the production line. For example, underwater pelletizing systems can be started without any problems to downstream equipment.
