2. Safety Instructions
DANGER!
- Before any maintenance of the valve, depressurize the line system
and discharge it if possible.
- Do not reach into the open valve or into the yoke!
Risk of bruising by movable parts.
- Valve in dismantled state: risk of injury by sudden
valve actuation!
- Observe the following service instructions to ensure safe
maintenance of the valve.
- The welded housing of the actuator is under spring load -
do not attempt to open it by force!

Butterfly Valve
DELTA SVS1F DN125-250
Operating Manual rev.2
Use of high-quality stainless steel and seal material 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.
The function of the butterfly valve is to shut off line sections.
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 inter-
changeable.
Actuation by pneumatic actuator.
Reset by spring force into the limit position closed.
Extension of operating time of actuated valves by pneumatic air
throttle or adjusting screw in the control unit CU3 to optimize the
flow behaviour.
The butterfly valve can also be used in vacuum systems.
The valve opens and closes by turning the disc by 90°. Manual
actuation provides for locking of the disc in partly open position.
Smooth valve passage without diversion of line flow.
The opening diameter complies with the size of the inner line
diameter.
Cleaning of the product wetted valve surface is performed during
cleaning of the pipeline.
4. Auxiliary Equipment
Valve position indication - valve with pneumatic actuator:
Proximity switches to signal the limit position of the valve disc
can be installed in the yoke area if required.
We recommend to use our APV standard proximity switches.
Type: three-wire proximity switch (ref.-No. 08-60-011/93)
Operating distance: 4mm / diameter: 11mm / length: 30 mm.
Feedback complete with support and proximity switch
(ref.-No. 15-33-023/93) for a limit position.
Using a valve position indicator other than APV, we cannot accept
any liability for faulty function.

5. Installation
UK
In normal installation position, the actuator is vertically to the top.
Depending on the requirements of the respective application, the
installation position is optional.
Valve installation can be undertaken between FG 1 flanges and
flanges according to DIN.
Attention : Observe welding instructions!
5.1 Welding Instructions
- Welding shall only be carried out by certified welders (EN 287 - 1).
(seam quality EN 25817 ,,B”).
- The welding of the mating flanges must be undertaken in such a way
that deformation strain cannot arise.
- TIG orbital welding is the most appropriate method!
- Before welding, all sensitive parts must be removed!
Dismantle the valve core with seals, etc. from the mating flanges.
- After welding of the mating flanges and after work at the pipelines,
the corresponding parts of the installation and 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.

- 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 SVS1F butterfly valves, principally
the SV seal, flange seals and bearings.
- 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.1)
- especially the cross bores.
- Assembly of valve and change of valve design NC or NO
see service instructions.
- Installation of actuator see 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-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 !!!

10.6 Installation of the actuating device
-Proceed in reverse order to the steps described in 10.2.
- With the manually operated butterfly valve, the valve disc and
the handle are in a line.
- For the assembly of the actuator, see to the requested
valve design NC or NO.
NC = normally closed
Valve disc is closed.
Place the pneumatic actuator with yoke and coupling on the valve
and tighten them with the screws (10).
The upper operating cam must be adjusted to the upper yoke bore.
NO = normally open
Valve disc is open.
Place the pneumatic actuator with yoke and coupling on the valve
and tighten them with the screws (10).
The lower operating cam must be adjusted to the lower yoke bore.
DANGER! After the assembly of the actuator, do not
touch the open valve! Risk of bruising by
movable valve parts! Risk of injury through
sudden valve operation!
10.7 Installation of feedback units
- Valve feedback OPEN:
