2.Note

Please read these operating instructions before unpacking and putting the unit

into operation. Follow the instructions precisely as described herein.

The instruction manuals on our website www.kobold.com are always for currently

manufactured version of our products. Due to technical changes, the instruction

manuals available online may not always correspond to the product version you

have purchased. If you need an instruction manual that corresponds to the

purchased product version, you can request it from us free of charge by email

([email protected]) in PDF format, specifying the relevant invoice number and

serial number. If you wish, the operating instructions can also be sent to you by

post in paper form against an applicable postage fee.

The devices are only to be used, maintained and serviced by persons familiar

with these operating instructions and in accordance with local regulations

applying to Health & Safety and prevention of accidents.

When used in machines, the measuring unit should be used only when the

machines fulfil the EC-machine guidelines.

as per PED 2014/68/EU

In acc. with Article 4 Paragraph (3), "Sound Engineering Practice", of the

PED 2014/68/EU no CE mark.

3.Instrument Inspection

All instruments are inspected before shipping and sent out in perfect condition.

Should damage to a device be visible, we recommend a thorough inspection of

the delivery packaging. In case of damage, please inform your parcel service /

forwarding agent immediately, since they are responsible for damages during

transit.

Scope of delivery:

The standard delivery includes:

•Flow Restrictors model: REG

4.Regulation Use

Any use of the Flow Restrictor, model: REG, which exceeds the manufacturers

specification may invalidate its warranty. Therefore, any resulting damage is not

the responsibility of the manufacturer. The user assumes all risk for such usage.

5.Operating Principle

KOBOLD model REG flow restrictors serve to keep constant quantities of liquids

in pipework systems. The REG rate regulators are ideally suited for the simple

restriction of a preset value of throughputs of water or of liquids similar to water.

The flow restrictors ensure an equilibrium, particularly in systems with many

consumers and resulting pressure fluctuations caused by random flow conditions.

In other words, the desired throughput is not exceeded.

Constant flow is achieved by two stainless steel spring plates that are crosswise

mounted and riveted together. The gap between the spring-loaded stainless steel

plate and the seal-surface is continuously varied as the differential pressure

changes. As the differential pressure decreases, the gap widens, and it closes as

the pressure increases, thus maintaining a constant flow volume through the

device.

6.Mechanical Connection

Before installation:

•Remove all transport securing devices and make sure that there are no more

packaging parts left in the device.

•Make sure that the permitted maximum operating pressures and temperatures

for the device are not exceeded (see 7 Technical Information)

•Install the flow limiter into the piping without mechanical stress.

•Protect the measuring pipe against external damage.

•Avoid pressure surges in the measuring pipe e.g. by blocking the flow quickly.

•If possible, after mechanical installation, make sure that the connection

between screw connection and pipe is tight and does not leak.

•Inlet and outlet run: the flow restrictor generally does not require any inlet and

outlet runs.

However, if a significant diameter reduction is necessary directly before or after

the restrictor, an inlet and outlet section of ∼3x DN must be set up.

Note the direction of flow: Depending on the design, the REG are marked with a

direction arrow or a label e.g. "IN".

Maximum tightening torques for process connection:

G ½ 30 Nm

G ¾ 30 Nm

G1 38 Nm

Warning! The differential pressure must not exceed 10 bar.
