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.
-The potential equalization between disc and housing by means of
the spring must generally be ensured.
-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 equalization must be
guaranteed!
The APV CU2, CU3 and CU4 Control Units are not suited for use in
ATEX environments!

3.3 Responsibilites
It is within the operator`s responsibility to ensure that the specied
product temperatures are not exceeded and that regular inspections
and maintenance are carried out to provide for proper function of
the valve.
4. Intended Use
The intended use as field of application of the butterfly valves
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.
Earthing of the valves must be guaranteed.
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
Use of high-quality steel and seal materials to the specified
requirements, the butterfly valve range DELTA SVS1F is applicable
in the food and beverage industries as well as in the chemical and
pharmaceutical industries.
Valves of the series DELTA SVS1F can either be operated manually
or remote controlled via a pneumatic actuator. Manual operation
and pneumatic actuator including add-on pieces are
interchangeable.
The valves are designed for universal applications and stand out
for their increased mechanical reliability and absolute ease of
service.
In the standard design "NC", the pneumatic turning actuator opens
the valve with compressed air.
Reset by spring force into the limit position "closed".
The butterfly valve can also be used in vacuum systems.
The valve opens and closes by turning the disc by 90°.
Smooth valve passage without diversion of line flow.
The opening diameter complies with the size of the inner line
diameter.
Proximity switches to signal the final position of the valve disc can
be mounted in the yoke area.
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!

5. ModeofOperation
5.2. PotentialEqualization
A possible risk may result from a potential difference between the
components. With non-conducting media or empty pipline sections,
a conducting connection must be created between the valve
components. With butery valves, this is reached by the installation
of a spring.
In explosive atmospheres, we generally recommend to ensure the
potential equalization between disc and housing by installation of
the spring mentioned below.

6. Cleaning
6.1. Cleaningrecommendation
The valve passage is cleaned by the cleaning liquids during
cleaning of the connected pipelines.
Depending on the degree and constituents of soiling, the cleaning
liquids, times and processes must be scheduled for the individual
application.
The compatibility of the individually selected cleaning processes
and liquids with the respectively used seals must be veried.
7. Installation
7.1. Generalterms
In normal installation position, the actuator is positioned vertically to
the top. Depending on the respective application, optional
installation positions can, however, also be realized.
SVS1F valves are intended for assembly between FG1 anges.
7.2. Connections
Standard plain anges FG1 between which the valve is installed,
form part of the scope of supply.
The anges have weld ends in the respective nominal dimension.
Attention! Observe Welding Instructions 7.3.

-Welding may only be carried out by certified welders (DIN EN ISO
9606-1). (seam quality DIN EN ISO 5817).
-Welding of the mating anges must be undertaken is such a way
that deformation strain cannot be transferred.
-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 the most appropriate method.
-Before welding, all sensitive parts of the valve must be removed!
Remove valve core with seals from the mating anges.
After welding of the mating anges 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 or be
carried over to other parts of the installation.
-Any damage resulting from the non-observance of these welding
instructions is not subject to our guarantee.

9. TechnicalData
9.3. Openingandclosingtimes
The actuating times depend on the length of the air line between
the magnet valve to the air control and the actuator.
For air lines with a length of up to 1 m, the opening time for
buttery valves DN 25/1” to DN 100/4” at 6 bar control air pressure
amounts to about 1 second. The closing time, after air shut-off,
depends on the nominal dimension and amounts to 2 to 3
seconds.
If the valves are subject to strong friction, e.g. through dry seals,
the actuating times extend accordingly.

11. Maintenance
The maintenance intervals depend on the corresponding
application and are to be determined by the operator himself
carrying out temporary checks.
Before start of maintenance and assembly the operator must make
sure that an explosive atmohsphere does not exist (detection/
measurement of potential concentration of hazardous substances).
Alternatively, use spark-resistant tools!
-There are a few wear parts on SV1 buttery valves, principally
the SV seal and bearings.
Customer stock keeping of spare seals is recommended.
For valve service actions we supply complete seal kits (see spare
parts lists).
-If damaged seals are replaced, generally all seals and bearings
should be changed.
-Dismantling and installation of seals according to Service
Instructions.
-All seals must be slightly greased before their installation.
Grease SV seal according to illustration - especially in the cross
bores.
-Assembly of valve and change of valve design NC or NO
by installation of the turning actuator according to Service
Instructions.
-The inner parts of the actuator are maintenance free.
Attention! Use food-grade special grease being suited for the
respective seal material, only.
Recommendation:
APV assembly grease for EPDM, FPM, HNBR and NBR
(0,75 kg /can - ref. No. 000 70-01-019/93, H147382)
(60 g /tube - ref. No. 000 70-01-018/93, H147381)
or
APV assembly grease for VMQ
(0,6 kg /can - ref. No. 000 70-01-017/93, H147380)
(60 g /tube - ref. No. 000 70-01-016/93, H147379)
! Do not use grease containing mineral oil for EPDM seals.
! Do not use Silicone-based grease for VMQ seals.
Less suited grease types can influence the function and
life time.
