1. General Terms

This operating manual has to be read and observed by the responsible operating and maintenance personnel.

We have to point out that we will not accept any liability for any 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!

- 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 -

o not attempt to open it by force!

3. Mode of Operation

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 interchangeable.

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.

4. Auxiliary Equipment

Valve position indication - valve with manual actuation:

Specific manual actuations with feedback feature are available: Feedback of both disc positions

open and closed are possible.

CONTROL UNIT

Units with feedback switch and solenoid valve for the pneumatic control of the valve for assembly on the actuator are also available in fieldbus technology.

The assembly of a CU3 control unit on a pneumatic actuator is possible.

The following different designs are available:

designation ID : CU 31 Direct Connect L 804 629

CU 21 Profibus L 804 437 CU 31 Device Net L 804 611 CU 31 AS - Interface L 804 701

- An adapter is required to install the control unit on the SVS1F valve.

designation ID : CU 2 adapter SVS1F / DKR2 L 801 195

- To install the control unit on a butterfly valve a special pneumatic actuator is needed.The standard actuator must be replaced.

5. Installation

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.

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 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).

SV seal

grease

- 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.

10. Service Instructions

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: Installation of the valve feedback in the lower yoke bore.

- Valve feedback CLOSED:
