Pressure Control Element Bellow DWB

Compressors, air conditioning and refrigeration devices, pressure differential switches, pressure switches, excess pressure
protection, safety function with TÜV type series

Technical design:

A change in pressure of the medium results via the active bellow surface in a change of displacement which is used as a constant control or switching function in connection with electronic or electro-mechanical components.
As for TÜV type series, the second, integrated control component is activated and used as a safety function in cases where the element has become leaky.

Testing, Tests, Simulation
System-oriented testing.
All of the EGELHOF products are tested in our state of the art simulation and test benches during product design.
These test installations are also offered as an external service.
