1. General Terms
2
This operating manual should be read carefully by the competent
operating and maintenance personnel.
We 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 of operating safety. You will find it wherever the activities
described are bearing risks of personal injury.
-Disconnect electrical and pneumatic connections
- Depressurize the line and cleaning system and discharge the lines,
if possible, before any maintenance work.
- Do not reach into the open valve!
Risk of bruising at movable parts of the valve.
-Risk of injury by sudden valve operation in dismantled valve state.
-Observe Service Instructions to ensure safe maintenance of
the valve.
- During the actuating process, operating leakages spurt out to the
bottom.
-Close cleaning connection and leakage drain which are not used
by a plug.
- DANGER!
Welded turning actuators are preloaded by spring force.
Turning actuators which are no longer used and / or defective
must be disposed in professional manner.
Defective turning 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.

3. Mode of Operation
Due to the use of high quality stainless steel and adequate
seal materials, the double seal butterfly valve DSV is suited for
applications in the food and beverage industries as well as in the
pharmaceutical and chemical industries.
The function of the double seal butterfly valve is to shut off line
sections.
It is exclusively suited for applications in the CIP area,
whereby the valve is subject to defined cleaning and flushing
processes.
Valves of the DSV series are remote controlled by a 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 valve opens and closes by turning the valve disc by 90°.
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.
Leakage arising in the area of the butterfly valve seal flow out in
depressurized state via the leakage drain.
The leakage chamber in the area of the double valve disc can be
cleaned via a cleaning connection.
As option, the DSV-valve is available in manual design.
The two final positions of the valve are fixed by locking of the
handle. The handle must be unlocked for change-over.

4.1 Valve position indication (for actuated valves only)
Proximity switches to signal the limit position of the valve disc can
be installed if required.
We recommend to use our APV standard proximity switches.
Type: three-wire proximity switch (ref.-No. 08-60-011/93)
Operating distance: 4 mm / diameter: 11 mm / length: 30 mm.
Using a valve position indicator other than APV type, we cannot
accept any liability for faulty function.
4.2 Control Unit fig. 4.2 (for actuated valves only)
Units with feedback switch and solenoid valve for the pneumatic
control of the valve to be assembled on the turning actuator are
also available in field bus technology. The assembly of a Control
Unit CU3 on the turning actuator is possible.
The following different designs are at disposal:

The DSV valve is designed only for the upright installation position
with actuator vertically to the top!
DSV valves are mounted between "flanges-DSV".
Attention: Observe welding instructions.
5.1 Welding Instructions
-Observe the bore position (see fig.) during the welding of the
mating flanges - DSV.
- Welding may 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 best!
- Before welding, all sensitive parts of the valve must be removed!
Remove the valve core with seals from 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 to our guarantee.

- The maintenance intervals depend on the application of the valve
and should be determined by the operator carrying out regular
visual checks of the valve.
- The double seal butterfly valve possesses only a few wear parts:
disc seal and bush bearings.
- The customer is recommended to hold spare seals and bush
bearings on stock.
For valve maintenance APV supplies complete seal kits including
seal grease (pl. see spare parts lists).
-If damaged seals are exchanged, generally replace all seals and
bush bearings.
-Slightly grease all seals before their installation.
Grease the disc seal according to the illustration - especially the
cross holes.
-Assembly of the valve and change of the valve design FZ
(normally closed) or FO (normally open) according to Service
Instructions.
-Installation of turning actuator according to Service Instructions.
- The inner parts of the turning actuator do not need service.
Attention! Use food-grade grease and special grease being
suited for the respective seal material, only.
Recommendation:
APV-food-grade grease for EPDM and HNBR
(0,75 kg /can - ref. No. 000 70-01-019/93)
(60 g /tube - ref. No. 000 70-01-018/93)
! Do not use grease containing mineral oil for EPDM seals.
