3. Mode of Operation
Membrane valves DELTA M4 have been developed for use in the
brewing and beverage industries, dairy and food applications as
well as in the chemical and pharmaceutical industries.
The function of the DELTA M4 valve is to shut off line sections.
The membrane valves offer optimum protection of the product in
hygienic and aseptic applications. Product safety is provided by the
hermetic separation of the product chamber from the environment
(atmosphere) by a flexible membrane.
- Operation by pneumatic actuator with air connection,
reset by spring force.
- By different assembly of the actuator, the following designs can
be realized:
NC: actuator normally closed
("fail-down": air-to-raise, spring-to-lower)
NO: actuator normally open
("fail-up": air-to-lower, spring-to-raise)
- The inner parts of the actuator are maitenance-free.
- The cleaning of the inner area of the valve is undertaken
during CIP cleaning of the line system.
- Leakages at the membrane are indicated at the leakage drain
in the yoke area.
- For the pneumatic control of the valve, a control unit is installed
on top of the actuator.
- The yellow luminous diodes installed in the control unit indicate
the position of the valve rod.
- For aggressive products, the MP design of the inner parts with
a membrane shaft out of TFM should be used.

-Valve position indication
For the valve position indication, a proximity switch holder (PSH)
can be installed direct on the actuator.
To signal the limit position of the valve seat, proximity switches can
be mounted to the holder if required.
We recommend our APV standard types:
operating distance: 5 mm / diameter: 11 mm.
If the user decides to apply valve position indicators other than
APV type, we cannot take over the liability for any malfunctions
resulting therefrom.
-Control Unit
The assembly of a control unit on the M4 valve is possible.
The following designs are available:

- The installation of the valve must be undertaken in such a manner
that fluids can drain off the valve housing and should be provided
preferably in vertical position.
- The valve housing can be welded direct into the pipeline
(completely dismantable valve insert).
-Attention: Observe welding instructions.
5.1 Welding Instructions
- Before welding of the valve, the valve insert must be dismantled
from the housing. Careful handling to avoid damage to the parts
is necessary.
- Welding should only be carried out by certified welders (EN 287-1).
(Seam quality EN 25817 "B").
- The welding of the valve housings must be undertaken in such a
way that the valve body is not deformed.
- The preparation of the weld seam up to 3 mm thickness must be
carried out as a square butt joint without air.
(Consider shrinkage!)
- TIG orbital welding is best!
- After welding of the valve housings or of the mating flanges and
after work at the pipelines, the corresponding parts of the
installation or pipelines must be cleaned from welding residues
and soiling. If these cleaning instructions are not observed,
welding residues and dirt particles can settle in the valve and
cause damage.
- Any damage resulting from the non-observance of these welding
instructions is not subject to our guarantee.
