This operating manual has to be read carefully and observed by
the competent operating and maintenance personnel.
We have to 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 system must be
depressurized.
-Do not reach into the open valve.
-Risk of injury by suddenly operating valve. In dismantled state there
is the risk of bruising at movable parts of the valve.
-Observe service instructions to ensure safe maintenance
of the valve.
-Attention!
With valve design NC (normally closed / air-to-raise,
spring-to-lower): Before releasing the housing screws, the
valve insert must be relieved by controlling the actuator.
-The welded actuator is under spring load, do not open it by force.

3. Mode of Operation
3
The Shut-Off and Change-Over Valves DELTA SWmini4
(DN10, 15, 20) have been developed for the use in the brewing
and beverage industries, in dairy and food applications as
well as for the chemical and pharmaceutical industries.
The valves are designed for universal applications and stand
out for their increased mechanical reliability and absolute ease
of handling.
The function of the DELTA SWmini4 valve is to shut off and
to change over line sections.
-Operation by pneumatic actuator with air connection at (A),
reset by spring force.
-By different assembly of the actuator, the following designs
are possible:
NC (FS):actuator normally closed (air-to-raise, spring-to-lower)
NO (FH): actuator normally open (air-to-lower, spring-to-raise)
(illustrations show NC design)
-The inner parts of the actuator are maitenance-free.
-As standard, the valves are manufactured without support
for proximity switches.
-The valve position is indicated optically in the yoke area.
Indication in the upper yoke bore:
Valve position closed NC (FS).
-The cleaning of the inner area of the valve is carried out during
cleaning of the line system.

Valve position indication
-A proximity switch holder for the limit position NC or NO
of the valve shaft can be installed directly on the actutor.
-We recommend to use our APV standard types:
operating distance: 5 mm / diameter: 11 mm.
If the operator decides to use valve position indicators other
than APV type, we cannot take over any guarantee for a
faultless function.
-Control Unit
The assembly of a control unit on the DELTA SWmini4 valve
is possible.
The following different designs are available:
Connections: Clamp connection according to ISO 2852
Valves are available complete with clamp
connections.
The combination of weld ends and
clamp connections is possible.

5. Installation
5
-Installation has to be done in such a way that fluids can drain
off the valve housing and is preferably to be realized in vertical
position.
-Shut-off valve SWmini41 / 42:
The valve housings can be welded direct into the pipeline
(completely dismantable valve insert with actuator).
-Change-over valve SWmini 43 / 44:
One or two detachable connections e.g. (clamps, etc.) must
be assembled to the ports of the upper housing to provide for
disassembly (e.g. for seal replacement).
-The position of the medium and upper housing ports to each other
can be mounted staggered by 90othrough the screw connections.
-Attention: Observe welding instructions.

5.1 Welding Instructions
Shut-off valve SWmini41 / 42
-Before welding of the valves, remove the valve insert from the
housing (see chapter 10.I.c. - d.).
See to a careful handling of the parts to avoid damage.
Change-over valve SW mini 43 / 44
-The lower housing part (1), only, can be welded direct
into the pipe system.
Before welding of the lower housing, partly dismantle the valve
(see chapter 11.I.d. - e. and 11.II. a. - d.).
Remove the lower housing seal from the upper housing.
Provide the upper housing and the upper pipeline with detachable
connections (flange, clamps, etc.).
See to a careful handling to avoid damage to the parts.
-Welding may 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 deformation strain cannot be transfered from the outside
to the valve body.
-The preparation of the weld 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 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 nonobservance of these welding
instructions is not subject to our guarantee.
