2. Safety Instructions
DANGER!
- The technical safety symbol draws your attention to important
directions of operating safety. You will find it wherever the activities
described are bearing risks of personal injury.
-Disconnect electric and pneumatic connections
- Depressurize the line and cleaning system and discharge the lines,
if possible, before any maintenance work.
- Do not reach for the open valve or yoke!
Risk of bruising at movable parts.
-Risk of injury by sudden valve operation in dismantled valve state!
-Observe Service Instructions to ensure safe maintenance of
the valve.
-Danger!
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 Solutions & Services company
for their professional disposal and free of charge for you.
Please address to your local APV representative.
Opening of the actuators is strictly forbidden.
Danger to life!

3. Mode of operation
UK
Use of high-quality stainless steel and seal materials to the
specified requirements, the butterfly valve range DELTA SV1B
and SVS1FB is applicable in the food and beverage industries as
well as in the pharmaceutical and chemical industries.
The function of the butterfly valve with positioner is to shut off
line sections and to control flow quantities in line sections.
The modulating butterfly valves of the ranges DELTA SV1B and
SVS1FB are controlled by a positioner TC 8630 (company Bürkert).
For the positioner a separate operating manual (see chapter 4.)
is available.
The positioner (E) provides for the specified allocation of
the valve position and input signal. It compares the input signal
(4-20 mA)from the modulating device with the turning position
of the valve and emits the output signal, i.e. the pneumatic set
pressure to the turning actuator (C).
Depending on the requirements, the modulating valve can be
operated normally closed (air-to-raise, spring-to-lower) or normally
open (air-to-lower, spring-to-raise).
NC - The turning actuator opens with set pressure and closes
with spring pressure.
NO - The turning actuator closes with set pressure and opens
with spring pressure.
The valve position can be monitored through an indicator in the
coupling area (B).
Reset by spring force.
The connections for the electric and pneumatic supply are located
laterally at the positioner (D).
Cleaning of the product-wetted valve surface is performed during
cleaning of the pipeline.
The valves can also be used in vacuum systems.

For the positioner a separate operating manual is available.
More detailed information:
www.buerkert.de
> products > process and control valves > postioner > TC8630
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.
DELTA SVS1FB – valves are provided for assembly between
FG1 flanges.
DELTA SV1B – valves with weld ends are welded directly into the
product line.
Separate dismantling by a flange connection, etc. in the continuing
pipeline should be provided.
Attention: Observe welding instructions.

5.1 Welding Instructions
-Observe the bore position during welding of the mating flanges of
the DELTA SVS1FB valve. (see fig. and table)
- Welding may only be carried out by certified welders (EN287-1).
(seam quality EN 25817 “B”)
- The welding of the mating flanges must be effected in such a way
that deformation strain cannot occur.
- TIG orbital welding is the most appropriate method.
- Before welding, all sensitive parts must be removed!
Dismantle the valve core with seals between the mating flanges.
-After welding 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 or be
carried over to other parts of the installation.
-Any damage resulting from the non-observance of these welding
instructions is not subject of our guarantee.

9. Maintenance
- The maintenance intervals depend on the application of the valve
and should be determined by the operator carrying out regular
checks of the valve.
- There are a few wear parts on butterfly valves, principally
the SV seal, flange seals and bearings.
Diverse o-ring seals between actuator, adapter and positioner.
-It is recommended that spare seals and bearings are kept by the
user.
Complete seal kits for the valve service are available
(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 fig. - especially the cross bores.
- 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-food-grade grease for EPDM, FPM, HNBR and NBR
(0,75 kg /can - ref. No. 000 70-01-019/93)
(60 g /tube - ref. No. 000 70-01-018/93)
or
APV-food-grade grease for VMQ
(0,6 kg /can - ref. No. 000 70-01-017/93)
(60 g /tube - ref. No. 000 70-01-016/93)
!!! Do not use grease containing mineral oil for EPDM seals !!!
!!! Do not use Silicone-based grease for VMQ seals !!!
