2. Safety Instructions
Installation, connection, start-up, maintenance and repair work must
onlybecarriedoutbyqualiedpersonnel.
The following aspects must be observed:
- The instructions of this manual together with all relevant instructions
for the components, equipment and installations installed.
- Warningsandinstallationsxedtothecomponents.
- Thespecicregulationsforandrequirementstothesysteminwhich
the valve is installed.
- The currently valid regional, national and international regulations.
- Any special requirement and national legislation relative to
theuseofammableliquidsortools,e.g.theriskofignition
in case of spark formation, must be observed.
It must be ensured that the group, the category and the temperature
class of the valve complies with the minimum requirements of the
operating environment!
Inammablegasmixturesordustconcentrationsinconnectionwith
hot, operational and movable parts of the valve can lead to serious
or fatal injury!
Before start of assembly the operator must make sure that an
explosive atmosphere does not exist (detection/measurement of
potential concentration of hazardous substances).
Conductive connection to the pipeline must be provided.
The integration into the internal potential equalisation must be
guaranteed!
If the valve is used for inflammable liquids, it must be observed that
every operating process is combined with an operating leakage.
This operating leakage liquid must be discharged in a closed
system.
The operator must consider this during the examination and
classicationofexplosiveatmospheresintheoutsidearea.
The APV CU2, CU3 and CU4 Control Units are not suited for use in
ATEX environments!

All data (temperature classes) refer to an ambient temperature
of 0°C to 40°C. If the ambient temperature is above 40°C, the
temperature difference must be adjusted. In all cases, contact your

4. Intended Use
The intended use as field of application of the DELTA SD4 double
seal valve is the shut-off of line sections, especially in beverage and
food installations.
Its use is permissible only within the admissible pressure and
temperature margins and under consideration of chemical and
corrosive influences.
Any use exceeding the margins and specifications set forth,
is considered to be not intended.
Any damage resulting therefrom is not within the responsibility
of the manufacturer.
The user will bear the full risk.
Attention!
Improper use of the valve leads to:
- damage
- leakage
- destruction.
Failures in the production process are possible.
Warning!
The valve is suitable for use in hazardous areas
as identified on the valve according to Directive 2014/34/EU.
Arbitrary, constructive changes at the valve will influence safety
as well as the intended functionality of the valve and are not
permissible.

5. ModeofOperation
5.1. General terms
DELTA SD4 double seal valves have been developed for use in
the brewing and beverage, dairy and food industries as well as for
chemical and pharmaceutical applications.
The valves are designed for universal applications and stand out
for their increased mechanical reliability and absolute ease of
service.
The field of application of the DELTA SD4 double seal valves is to
shut off line sections which are separated from one another by two
seat seals. A leakage chamber is arranged between the seals, the
leakage chamber being forcibly closed by the two leakage valves or
opened to the atmosphere.
- Operation by pneumatic actuator with air connection, reset by spring
force.
- The inner parts of the actuator need not be serviced.
- To avoid pressure hammers, the valve is to be closed against the
flow direction of the fluid.
- The SD4 valve is equipped with a valve position indication.
The proximity switches to signal the final position of the valve disc
can be mounted to the proximity switch holder (PSH).
The use of valve position indicators which are approved for the
application in explosive atmosphere is compulsary.
The use and operation of valve position indicators shall be
evaluated by the operator of the installation!
Assembly, see item 13.3.

6. Cleaning
For the cleaning of SD4 valves, distinction is made between two
areas.
6.1. Theflowchambers
The passages of the valve are cleaned by the cleaning liquid during
cleaning of the connected pipelines.
6.2. Theleakagechamber(fig.6.2.)
Cleaning of the leakage chamber is undertaken via the leakage
valves. The cleaning liquid is supplied via one leakage valve and
discharged to the atmohsphere in a closed process via the second
leakage valve.
The restraint passage of the cleaning liquid provides for a perfect
cleaning of the whole leakage chamber.
- Flushing quantity per CIP cycle: about 1.2 tr / 10 s
- Cleaning pressure at CIP cleaning connection: min. 2 bar
max. 5 bar
Under standard operating conditions, 15 valves DN 25/1” - 100/4”
can be cleaned via one spray distribution line DN 25.
6.3. Cleaning(leakagechamber)
Recommendation of cleaning cycles with standard operating
conditions and CIP liquids.
Cleaning steps CIP-spraying
Pre-flushing 3 x 10 sec.
Caustic flushing 80°C 3 x 10 sec.
Intermediate flushing 2 x 10 sec.
Acid flushing 3 x 10 sec.
Subsequent flushing 2 x 10 sec.

6. Cleaning
- Depending on the degree and substances of soiling, cleaning
liquids, times and processes must be scheduled for the individual
application.
The compatibility of the individually selected cleaning processes
andliquidswiththerespectivesealmaterialmustbeveried.

7. Installation
7.1. Generalterms
Installation must be undertaken in such a way that liquids can drain
off and should preferably be carried out in vertical position.
The valve housing can be welded direct into the pipeline system
(completely dismantable valve insert).
Attention! Observe Welding Instructions 7.2.
Conductive connection to the pipeline must be provided.
The integration into the operational potential equalization must be
guaranteed!

7. Installation
7.2. 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 (DIN EN ISO
9606-1). (Seam quality DIN EN ISO 5817).
- 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.
