1. General

This operating manual must be read and observed by everyone involved with the installation, commissioning, operation

and maintenance of the non-return valve.

This operating manual applies to the following valve versions:

Types Equipment

FLOWmag 12020

Magnetic non-return valve

with weld ends or threaded pipe connections

FLOWmag 12021

Magnetic non-return valve in intermediate flange design

with weld ends

Proper Application

•The non-return valve is used in the food and beverage industry and the pharmaceutical and chemical industry.

•Non-return valves prevent return flow in the direction opposite flow or prevent

connected pipe systems from flowing through. The valve is normally closed.

•The valve may be used for the intended purpose only. Pay close attention

to the installation situation and/or flow direction, the specified pressure and temperature range

and the flow media.

•Applicable and generally recognised safety rules as well as the operating manual instructions must be

followed during assembly and disassembly, in operation and during maintenance.

Incorrect Application

The following are examples of incorrect application:

•Operating conditions other than those specified in the operating manual are present.

•Liquid media different to that envisaged in the operating manual flow through the valve.

•The safety information is disregarded during operation, assembly and maintenance.

•Independent modifications or changes to the valve are carried out that

restrict safety or functionality.

•Valves are used although they are not functional.

The User's Duty to Exercise Diligence

The user must especially ensure that:

•The installation of the valves is carried out in accordance with the instructions.

•The valves are operated according to their intended purpose and are in a fully functional state.

•The statutory requirements for operation, assembly and maintenance are observed.

•Only sufficiently qualified and authorised personnel maintain the valves.

2.2 Safety Instructions

Note

The following safety information must be considered as an addition to the relevant

applicable national accident prevention requirements and laws.

Current standards of good engineering practice must be observed when planning the

application and operation of the device.

Please pay attention to the relevant rules and safety regulations in other countries.

Basic safety instructions

to prevent injuries and to ensure correct functioning:

•Transportation and storage are carried out correctly in accordance with the operating

manual.

•Installation and maintenance tasks as well as operating actions should

only be carried out by appropriately authorised and qualified personnel with suitable

tools.

•The device should only be installed and operated when in efficient working order and

in accordance with the operating manual.

Risk of injuries!

•The valve must be switched off in the case of

noticeable malfunctions.

•The area of the line where the valve is located

must be locked within the system.

•Disassembling the valve from the piping

system without relieving the system pressure

first may result in burns, scalding or chemical

burns.

•If the valve in a system is operated with acidic

or alkaline media, your hands and fingers may

suffer chemical burns when disassembling the

valve.

•If the valve in a piping system is operated

with hot media, the surface temperature of

the valve can also reach this value.

•There is a risk of crushing due to moving

parts.

oFaults must be eliminated

immediately.

oUnintentional commissioning

must be prevented.

oMake sure that the piping system

pressure has been relieved.

oMake sure that the piping system

has been flushed and emptied.

oMake sure that the piping system

has cooled to a value below 50°C.

oNever reach into the switching

section of the valve.

3. Delivery and Performance, Storage

•Check the information on the delivery note for correctness and check the delivery for

completeness. Later complaints will not be accepted.

•Conduct a visual inspection for transport damage. The forwarding agent must be informed of any visible damages

immediately (comment on the waybill).

•Claims due to transport damage not visible right away must be made to the forwarding agent within a week.

•Store the delivery in dry rooms and, if possible, in the original packaging to protect it against external factors.

4. Function and Operation

4.1 Valve Description

These non-return valves are for low-bacteria/sterile processes in the beverage and food industry as well as in the

chemical-pharmaceutical sector

The non-return valve is equipped with a permanent magnet. Because the pressure spring was eliminated, other

components installed in the product area are also eliminated, which makes cleaning and sterilising considerably easier.

The valve types 12020 / 12021 are characterised by:

•open flow, gentle product handling

•flow with almost no pressure loss

•secure closing, no backflow

•hygienically designed shutter and product area

•patented, magnetic functional principle

4.2 Valve Operation

The conventional pressure spring has been replaced with an external magnetic field. If the flow of liquid is

interrupted, the shutter is pushed against the valve seat, thus preventing backflow.

If the liquid pressure exceeds the force of the magnetic field, the valve opens.

The liquid can then flow through the product area unhindered.

Risk of injuries!

See Chapter 2.2 - Safety Information

Note

Installation position of the valve or draining of the pipeline and flow direction in the valve.

Non-return valves should be cleaned within a defined time period (cleaning schedule).

Generally this is done during pipe cleaning / flow.

Note

Only use cleaning agents which are appropriate for stainless steel and the seals. Please

refer to the safety data sheets of the cleaning agents.

5. Assembly and Disassembly

5.1 Safety and Assembly Instructions

Risk of injuries!

Permanent magnet

•All electronic objects can be damaged by the magnetic field or their function can be

impaired.

This also applies to medical/electrical devices, for example heart pace makers,

hearing aids, etc.

•To exclude possible risks, the valves should only be maintained by personnel who are

instructed in devices of this type.

Risk of injuries!

See Chapter 2.2 - Safety Information

Caution – danger zone warning! (also see Chapter 2)

Please pay attention to the following prior to installation and commissioning:

•Check the valve for visible external and internal damage.

•Check the valve housing inside for residues.

•Check the current system status (pressure, temperature, medium).

Please pay attention to the following if malfunctions occur and prior to disassembly:

•The valve must be switched off in the case of malfunction.

•Check the current system status (pressure, temperature, medium).

Caution – functional impairment or material damage!

Installation instructions:

•Valves for welding in must be previously disassembled or the magnet and

seals must be removed. The housing cannot be welded in with a magnet installed!

•Weld the housing into the piping system free of tension with sufficient free space.

•Remove welding residue from the piping system.

•The welding work (TIG, welding gas) should only be carried out by qualified welders (EN

287-1).
