Ventilation Control Centre PLZ

The manual operation OPEN/CLOSE is realized via an integrated pneumatic valve HH5/2 and other add-on components, depending on the chosen configuration. In case of electric control, the ventilation control centre can be controlled for example via a wind and rain control, type WRS.

A valve with a nominal bore of  4 mm is used to manually OPEN and CLOSE ventilation cylinders. The door of the sheet steel ventilation box opens downwards. Two keys are included in the delivery.
As a standard, the PLZ is connected with bulkhead fittings for 6 mm or 8 mm OD hoses or pipes. It also contains an adjustable filter pressure reducer with operating pressure gauge, water separator and condensed water drain plug.
