5. Mode of Operation
5.1.
General terms
- Aseptic modulating valves RGMS4 can be used for the continuous
regulation of material flows in the beverage and food industries and
in chemical and pharmaceutical applications.
-
The modulating valves are suited for the flow and pressure
regulation of fluids and gases.
- An optimum protection of the product in hygienic and aseptic areas
is guaranteed.
- At the shaft passages product safety is reached by the hermetic
separation of the product chamber from the outside (atmosphere)
by a flexible diaphragm.
- In its basic shape, the Delta RGMS4 is designed as a corner
valve. Therefore, the valve proves favourable flow deviation
characteristics. The flow direction is from A to B (fig. 1).
- The housing which is free of dead spaces has optimum cleaning
features. Crevice-free sealing of the individual housing parts by
profile seals - no source of infection.
- Leakages at the diaphragm are indicated in the yoke area via a
leakage drain (L).
-
The interdependence between flow and cone stroke is defined by
the characteristics.
-
Different kvs values (flow) with a certain valve dimension can be
reached by different inserts (valve seat / valve cone). (fig. 1)
- The table in Item 12. shows the parts to be changed in case of
modification of the kvs value.
- The connections (G) or the electric and pneumatic supply are
located laterally at the positioner (C).
- An optical position indication (stroke indication) is located in the
yoke area (E).
