PRESSURE REDUCER DAT096
3 DESCRIPTION
The manual pressure regulator 0 - max. 7 bar is used to regulate the pressures in the material lines. A star grip
adjustment spindle is located on top of the device. Screwing it in manually pre-tensions a pressure spring, which
activates a tappet in the lower part of the device which, in turn, pushes a ceramic ball out of its sealing seat. This frees
up the flow of material. The controlled pressure of the material is now set on the outlet side. Unscrewing the regulating
rod releases the pressure spring tension and closes the sealing seat.
We reserve the right to make technical changes!
