must be observed during commissioning, operation and main-
tenance. Non-compliance with these instructions may cause:
•Personal hazard due to electrical, mechanical and chemical
effects.
•Hazard to nearby equipment.
•Failure of important functions.
•Hazard to the environment due to the leakage of dangerous
materials.
The safety information does not take into account:
•Unexpected incidents and events, which may occur during
installation, operation and maintenance.
•Local safety regulations which must be adhered to by the
operator and by any additional installation personnel.
Prior to commissioning:
1. Transport and store the product correctly.
2. Do not paint the bolts and plastic parts of the product.
3. Carry out installation and commissioning using trained
personnel.
4. Provide adequate training for installation and operating
personnel.
5. Ensure that the contents of the document have been fully
understood by the responsible personnel.
6. Define the areas of responsibility.
7. Observe the safety data sheets.
8. Observe the safety regulations for the media used.
During operation:
9. Keep this document available at the place of use.
10. Observe the safety information.
11. Operate the product in accordance with this document.
12. Operate the product in accordance with the specifications.

6 Technical data
6.1 Medium
Working medium: Corrosive, inert, gaseous and liquid media which have no negative impact on the physical and
chemical properties of the body and diaphragm material.
The valve will seal in both flow directions up to full operating pressure (gauge pressure).
6.2 Temperature
Media temperature: Valve body material Media temperature
PVC-U, grey (code 1) 10 — 60 °C
ABS (code 4) 10 — 60 °C
PP, reinforced (code 5) 5 – 80 °C
PVDF (code 20) -10 — 80 °C
Inliner PP-H grey / outliner PP, reinforced (code
71)
5–80 °C
Inliner PVDF / outliner PP, reinforced (code 75) -10 — 80 °C
PP-H, natural (code N5) 5–80 °C
Ambient temperature: Valve body material Ambient temperature
PVC-U, grey (code 1) 10 — 50 °C
ABS (code 4) -10 — 50 °C
PP, reinforced (code 5) 5 — 50 °C
PVDF (code 20) 0 — 50 °C
Inliner PP-H grey / outliner PP, reinforced (code
71)
5 — 50 °C
Inliner PVDF / outliner PP, reinforced (code 75) -5 — 50 °C
PP-H, natural (code N5) 5 — 50 °C
If the emergency power module is used (control module code A1, A2), the maximum ambient tem-
perature is reduced to 40 °C.
6.3 Pressure
Operating pressure: 0 — 6 bar
All pressures are gauge pressures. Operating pressure values were determined with static operating pressure
applied on one side of a closed valve. Sealing at the valve seat and atmospheric sealing is ensured for the given
values.
Information on operating pressures applied on both sides and for high purity media on request.
The operating pressures apply at room temperature. In case of deviating temperatures, observe the pressure /
temperature correlation.

ature generate a combined temperature at the valve body which must not exceed the above values.

Kv values in m³/h
MG = diaphragm size
Kv values determined acc.to DIN EN 60534 standard, inlet pressure 5 bar, Δp 1 bar, PVC-U valve body and soft
elastomer diaphragm.
The Kv values for other product configurations (e.g. other diaphragm or body materials) may differ. In general,
all diaphragms are subject to the influences of pressure, temperature, the process and their tightening torques.
Therefore the Kv values may exceed the tolerance limits of the standard.
The Kv value curve (Kv value dependent on valve stroke) can vary depending on the diaphragm material and dur-
ation of use.
