1. General Terms

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.

Opening of the turning actuators is strictly forbidden.

Danger to life!

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. Auxiliary Equipment

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:
