2. Note

Please read these operating instructions before unpacking and putting the unit
into operation. Follow the instructions precisely as described herein.
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
 Operating Instructions

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.

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.
