News: manual slide valve HSV700

New configuration of HSV manual slide valve

We have simplified our HSV700 series to reduce handling and storage. The model for NG6 CETOP assembly consisted of a valve for manifold assembly and a CETOP adapter plate, which were offered as a complete set.

In order to simplify the overview of our valve models, we now offer only two instead of three different mounting versions. To achieve the third version, the manifold is now offered with an optionally available adapter plate.
