3. Transport, storage, packaging
3.1. Transport inspection
Upon receipt check delivery for any damages caused
during transit.
Any damages must be reported immediately upon receipt.
3.2. Storage
The differential pressure regulator "Hycocon DTZ" must only
be stored under the following conditions:
– Do not store in open air, keep dry and free from dust.
– Do not expose to aggressive fluids or heat sources.
– Protect the regulator from direct sunlight and mechanical
agitation.
– Storage temperature: -20°C up to +55°C,
max. relative humidity of air: 95%
Attention:
– Please protect against external forces (e.g. im-
pacts, vibrations etc.).
– External components such as handwheels, pres-
sure test points, actuators should not be used as
lever points during installation.
– Suitable means of transport and fitting devices
have to be used.

The recommended application range is determined by the
minimum flow rate (q m min.) and the maximum flow rate
(q m max.).
Design of the regulator can be carried out with the help of
the charts illustrated above. Depending on the flow rate
and the differential pressure, the suitable regulator can be
determined. The curve q m max. constitutes the maximum
permissible flow through the valve. The curve q m nom. in-
dicates the condition where the system differential pres -
sure and the set nominal value are equal.
