Series 4000

In the sector of hygienic applications or clean service applications, very high requirements are applied on optimal cleanability and dead space free construction of equipment parts.

At the development of the new safety valve series 4000, ranging from DN 25 to DN 100, these exact principles have been fulfilled and therefore exist in a safety valve for the first time.

By using a conical diaphragm instead of a rubber flange, the area affected by the medium is optimally separated from the spring housing. On all surfaces, the primary conical valve seal and the housing seals, these principles have been fully implemented. Thus all surfaces are easy to clean.

For the lifting of the valves, additionally there is a pneumatic piston actuator and optionally a proximity switch for the display of the valve opening available.
