WORKING PRINCIPLE

The valve is a pneumatic seat valve in a hygienic and modular designfor a wide field of duties, e.g. as a shut-off valve with two (2) orthree (3) ports or as a change-over valve with three (3) to five (5)ports. The valve is remote-controlled by means of compressed air. lthas few and simple moveable parts which results in a very reliablevalve and low maintenance cost.
