This operating manual should be read carefully by the competent
operating and maintenance personnel.
We point out that we will not accept any liability for damage or
malfunctions resulting from the non-compliance with this
operating manual.
Descriptions and data given herein are subject to technical
changes.
2. Safety Instructions
DANGER!
- The technical safety symbol draws your attention to important
directions for operating safety. You will find it wherever the activities
described are bearing risks of personal injury.
- Electric and pneumatic connections must be separated.
- Before any maintenance of the valve, the line and cleaning systems
must be depressurized and discharged if possible.
- Do not reach into the open valve.
Risk of injury!
- Observe service instructions to ensure safe maintenance of the
valve. The valve must only be assembled, disassembled and re-
assembled by persons who have been trained in APV valves or by
APV service team members. If necessary, contact your local APV
representative.
- When the diaphragm is damaged, leakages drain off the leakage
bore in the yoke area.
-Attention!
Valve design NC (normally closed): Control the actuator
with air before releasing the housing screws.
-Attention!
Welded actuators are preloaded by spring force.
Actuators which are no longer used and / or defective
must be disposed in professional manner.
Defective actuators must be returned to your
APV Sales & Service company for their professional disposal
and free of charge for you.
Please address to your local APV representative.

3. 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.
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:
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.
- 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.

4.1 Valve position indication (fig. 4.1)
A valve position indicator can be installed direct at the actuator.
Proximity switches to signal the limit position of the valve
seat can be installed at the proximity switch holder (PSH)
if required.
We recommend to use one of our APV standard types:
operating distance: 5mm / diameter: 11mm.
If the customer decides to use a valve position indicator
other than APV type, we cannot take over any liability for
any malfunctions.
4.2 Control Unit (fig. 4.2)
The MS4 valve can be equipped with a control unit.

- Installation has to be undertaken in such a way that fluids can
drain off the valve housing and should preferably be done 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
MS4
- 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 in butt manner as a square butt joint without air.
(Consider shrinkage!)
- TIG orbital welding is best.
- After welding of the valve housing or of the mating flanges and after
work at the pipelines, the corresponding parts of the installation or
pipeline 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.

or polishing material. Especially the valve shaft must not, under any
circumstances, be cleaned with such agents.
Damage of the valve shaft can lead to leakages.
- Replacement of seals according to Service Instructions.
Customer stock keeping of spare seals is recommended.
For valve service we supply complete seal kits including
seal grease (see spare parts lists).
Required tools:
- 1x wrench SW13
- 1x wrench SW17
- 1x wrench SW19

Remove the centering washer.
2. Extract the shaft with guide rod (3), diaphragm (5), fan (6),
upper shaft (4) and diaphragm support (7) from the actuator (14).
Remove the seat seal (2) and o-ring (16).
3. Remove the yoke (9) from the actuator (17).
- Actuator can be maintained.
(see 10. Service Instructions - Actuator).
4. Detach the o-rings (15, 13) and guide bush (11) from the yoke (9).
5. Clean the valve housing, yoke, actuator and shaft with a low
solution of a cleaning agent. Never use cleaning agents
containing abrasive or polishing material.

9.3. Installation of seals and assembly of valve
All seals must be provided with a thin layer of grease
before their installation.
1. Insert the guide bush (11) and o-ring (13) in the yoke (9).
Insert the o-ring (15) in the groove of the yoke.
Fasten the yoke (9) at the actuator (17).
2. Install the seat seal (2) in the lower valve shaft (3).
(see Service Instructions 11.)
3. Install the o-ring (16) in the fan (6).
Place diaphragm and fan on the upper shaft.
4. Wind the protective pipe over the thread of the guide rod.
5. Pass the guide rod through the upper shaft with diaphragm and fan
until it stops on the lower shaft. Insert the diaphragm support into
the fan.
! Toothing of fan and diaphragm support must interlock.
6. Insert the pre-assembled lower shaft with guide rod, diaphragm,
fan, upper shaft and diaphragm support through the yoke (9) and
actuator (17).
- The upper shaft must be guided through the guide bush into the
yoke in smooth-running manner. In case of mechanical stiffness,
check the right fit of the guide bush.
7. Design with control unit and valve position indication
Place the centering washer (21). Apply a drop of a screw locker,
e.g. type Loctite, semi-solid, on the thread of the guide rod. Screw
on the hex. nut (22) and fasten it with a tightening torque of
Md = 40 Nm. Hold up the centering washer during this process.
! Control Unit: Fasten the plastic actuator screw.
! Valve position indicator:
Fasten the metallic actuator screw.

9.4. Installation of DELTA MS4 valve
1. Design with Control Unit:
Fasten the adapter on the actuator.
Place the control unit (26) on the adapter (27) and fasten it
with the ring.
Design with valve position indication:
Fasten the housing of the valve position indication (24).
2.Version NC: During the assembly of the valve insert
observe the following:
-Control the actuator (version: NC) with pneumatic air min 6bar.
Carefully place the valve insert into the valve housing.
The diaphragm (5) must not be damaged during the installation
in the valve housing. Tighten the hex. screws (14) crosswise in the
housing flange.
Do not reach for movable parts!
Risk of injury.
!Version NC: Shut off air supply.
3. Check the basic adjustment of the valve position indication.
- By turning the positioning screw in the control unit, the shift points
can be adjusted.
4. Design with valve position indication:
Push in the proximity switches and fasten them.
- Readjust the proximity switches if necessary.
5. Adjustement of proximity switches: (fig. 9.4)
- Drive the actuator into a limit position.
- Drive the corresponding proximity switch into the corresponding
position. For this purpose release the positioning screw and move
the holder until the corresponding signal is indicated. Then,
continue to slide the holder by 2 to 3 mm in order to secure the
indication. Fasten the positioning screw.
- Position the actuator in the other limit position and carry out
the positioning of the second proximity switch.
- Upper valve position indication: valve NO “normally open”
(air-to-lower, spring-to-raise)
- Lower valve position indication: valve NC “normally closed”
