Mode of Operation

The diaphragm valves DELTA MS4 have been designed for
use in the brewing and beverage industries, in the dairy
and food industries as well as for chemical and pharmaceutical
applications.
The field of application of the DELTA MS4 valve comprises the safe
shut-off of pipeline sections.
DELTA MS4 diaphragm valves offer optimum product protection
in hygienic and aseptic applications.
actuator
Product safety is provided by the hermetic separation of the
product chamber to the exterior (atmosphere) by means of a
diaphragm with fan support.
- Operation by pneumatic actuator with air connection,
reset by spring force.
- Through different assembly of the actuator, the following designs
are possible:
yoke
NC: actuator normally closed (NC); air-to-raise, spring-to-lower
NO: actuator normally open (NO); air-to-lower, spring-to-raise
- The inner parts of the actuator are maintenance-free.
housing
- Cleaning of the valve interior is undertaken by CIP - cleaning of the
pipeline system.
- Leakages at the diaphragm are indicated in the yoke area through
a leakage drain.
- For the pneumatic control of the valve, a control unit is mounted on
top of the actuator.
- The yellow luminous diodes in the control unit indicate the position
of the valve shaft.
